Operational and strategic risks on projects
Introduction
Risk management is an important component of all project management frameworks and methodologies, so most project managers are well aware of the need to manage risks on their projects. However, most books and training courses offer little or no guidance about the relative importance of different categories of risks. One useful way to look at risks is by whether they pose operational or strategic threats. The former category includes risks that impact project execution and the latter those that affect project goals. A recent paper entitled, Categorising Risks in Seven Large Projects – Which Risks do the Projects Focus On?, looks at how strategic and operational risks are treated in typical, real-life projects. This post is a summary and review of the paper.
Operational and strategic risks
For the purpose of their study, the authors of the paper categorise risks as follows:
- Operational risk: A risk that affects a project deliverable.
- Short term strategic risk: A risk that impacts an expected outcome of the project. That is, the results expected directly from a deliverable. For example, an order processing system (deliverable) might be expected to reduce processing time by 50% on average (outcome).
- Long term strategic risk: A risk that affects the strategic goal that the project is intended to address. For example, an expected strategic outcome of a new order processing system might be to boost sales by 25% over the next 2 years.
It is also necessary to define unambiguous criteria by which risks can be assigned to one of the above categories. The authors use the following criteria to classify risks:
- A risk is an operational risk if it can impact a deliverable that is set out in the project definition (scope document, charter etc.) or delivery contract.
- A risk is a short-term strategic if it can have an effect on functionality that is not clearly mentioned in the project documentation, but is required in order to achieve the project objectives.
- A risk is considered to be a long-term strategic if it affects the long-term goals of the project and does not fall into the prior two categories.
The authors use the third category as a catch-all bucket for risks that do not fall into the first two categories.
Methodology
The authors collected data from the risk registers of seven large projects. Prior to data collection, the conducted interviews with relevant project personnel to get an understanding of the goals and context of the project. Further interviews were conducted, as needed, mainly to clarify points that came up in the analysis.
A point to note is that the projects studied were all in progress, but in different phases ranging from initiation to closure.
Results and discussion
The authors’ findings can be summed up in a line: the overwhelming majority of risks were operational. The fraction of risks that were classified as long-term strategic was less than 0.5 % of the total (with over 1300 risks were classified in all).
Why is the number of strategic risks so low? The authors offer the following reasons:
- Strategic risks do not occur while a project is in progress: The authors argue that this is plausible because strategic risks are (or should be) handled prior to a project being given the go-ahead. This makes sense, so in a well-vetted project strategic risks will occur only if there are substantial changes in the hosting organisation and/or its environment.
- Long term strategic risks are not the project’s responsibility: This is a view taken by most project management methodologies: a project exists only to achieve its stated objectives; its long-term impact is irrelevant. Put another way, the focus is on efficiency, not (organisational) effectiveness (I’ll say more about this in a future post). The authors recommend that project risk managers need to be aware of strategic issues, even though these are traditionally out of the purview of the project. Why? Well, because such issues can have a major impact on how the project is perceived by the organisation.
- Strategic risks are mainly the asset owner’s (or sponsor’s) responsibility: According to conventional management wisdom strategic risks are the responsibility of management, not the project team. In contrast, the authors suggest that the project team is perhaps better placed to identify some strategic risks long before they come to management’s attention. From personal experience I can vouch that this is true, but would add that it can be difficult to raise awareness of these risks in a politically acceptable way.
Conclusion
The main point that the article makes is that strategic risks, though often ignored, can have a huge effect on projects and how they are viewed by the larger organisation. It is therefore in important that these risks are identified and escalated to sponsors and other decision makers in a timely manner. This is a message that organisations would do well to heed, particularly those that have a “shoot the messenger” culture which discourages honest and open communication about such risks.
On the relationship between projects and organisations
Introduction
Most of the research and practice literature on project management tends to view projects as being isolated from their environment. It is obvious to anyone who has worked on a project that this isn’t so. In view of this, it is useful to look at the relationship between projects and the organisations that host them. This post looks at this issue, drawing on a paper by Gernot Grabher entitled, Cool Projects, Boring Institutions: Temporary Collaboration in Social Context.
The emergence of projects
Grabher begins his discussion with a sketch of the how projects emerged as a distinct work form. Projects – i.e. time bound, goal focused activities – have always been around. The modern notion of a project, however, arose from a development philosophy that came out of the US Department of Defense in the 1950s. He states,
…Instead of fragmenting and pre-specifying the development of military technologies along functional disciplines, these technologies were described in relation to their objectives, i.e. the military parameters of these weapons. The pacing of these concentrated efforts was crucial: parameters had to be met, goals had to be accomplished according to a grand scheme (program?) to win the armament race. Development processes that earlier were seen as separate activities were now conceptualized as an integrated entity called a program, system or project. The overwhelming scale of these projects in terms of financial and scientific resources as well as their ambitious timing created formidable problems of coordination and control. Experiments with various forms of organizational control ultimately lead to the professionalization of the role of the project manager…
From thereon the concepts of projects and project management were taken up (with much enthusiasm and optimism) by business and industry. The formalization of various project management methodologies, standards , qualifications and trade journals can be seen a culmination of this process.
Given the military-industrial origins of the profession, it is easy to see why a “command and control” philosophy dominates much of project management thought and practice. Many of the early projects that are paraded as textbook examples of successful projects operated outside normal organizational oversight. They were, to a large extent, deliberately shielded from external influences. I believe this is why isolation from the environment is seen as a Good Thing by project managers – problems of coordination and control become so much simpler when one does not have to manage relationships and politics that are (perceived as being) external to a project. This practice may be necessary and workable for classified projects that run on billion dollar budgets, but it doesn’t work so well in environments that most project managers work in. Projects don’t take place in a vacuum; they are born, live and die in real-world organizations. To forget that is to see the “tree of the project” and miss the “forest of the organization.” This is particularly so because, unlike those near-mythical mega-projects of the 1950s, the efforts that you and I work on are deeply entwined with their hosting organizations.
Organisation-related characteristics of projects
Grabher then notes some characteristics of projects. I summarize these in the next few paragraphs.
First, it is interesting that the original meaning of the word “project” referred to a “proposal” or “idea”, rather than a “directed, time-bound effort.” Grabher points out that this shift in meaning was accompanied by a shift in focus: from project as idea (or goal) to project as process (or means to achieving a goal). Projects are thus seen as vehicles for achieving organisational goals.
Second, Grabher notes that projects are often hard to decompose into constituent tasks, and that such a (commonly agreed) decomposition is only possible when stakeholders interrelate with each other continually. This underscores the importance of communication in projects.
Third, Grabher highlights the importance of the project manager (he uses the term contractor) as the “lynchpin on whom trust is focused.” The role of the manager is particularly important in projects on which team members do not have the time to get to know each other well.
Fourth, the project manager / contractor is also the wielder of organizational authority as far as the project is concerned. He or she is, in this sense, a representative of the organization – a person whose presence underlines the fact that the project exists to achieve specified organizational goals.
Finally, deadlines are a defining aspect of projects. They serve several functions. For example, they ensure that a sense of urgency for action and progress remains through the duration of the project. They also might serve to legitimize execution of project work without external interference (this argument was frequently used in the military-industrial projects of the 1950s). But above all, the final deadline, which culminates in the termination of the project, also serves as a connector to the rest of the organization. It is a time in which handoffs, documentation, team disbanding etc. occurs, thus enabling the results and experiences from the project disperse into the wider organization.
Projects in organisations
The characteristics noted above highlight the dual nature of projects: on the one hand, as noted earlier, projects are seen as semi-autonomous temporary organisations, but on the other they are also firmly embedded within the hosting organisation. An effect of the latter is particularly evident in consulting and software services firms (or even corporate IT shops), which tend to do similar projects over and over. As Grabher notes,
[projects] apparently operate in a milieu of recurrent collaboration that, after several project cycles, fills a pool of resources and gels into latent networks. Project organising is mostly directed towards the actual realization of a potential that is generated and reproduced by the practice of drawing on core members of (successful) prior projects to serve on derivative successor projects. Such chains of repeated co-operation are held together (or cut off ) by the reputation members gain (or lose) in previous collaborations…
Another aspect of embedded-ness is the co-location of team members within a larger organizational milieu. The standard benefits of co-location are well known. These are:
- Savings of transactional costs such as those incurred in communication, supervision of staff at remote locations etc. See my post on a transaction cost view of outsourcing for more on this.
- Co-location improves the efficacy of communication by encouraging face-to-face interactions.
- It enables “near real-time” monitoring of the health of the project and its environment.
There’s more though. Grabher notes that in addition to the above “intentional” or “strategic” benefits, co-location also ensures that team members are exposed to the same organizational noise – which consists of a “concoction of rumours, impressions, recommendations, trade folklore and strategic misinformation (falsehoods!).” Co-location enables project teams to make collective sense of organisational noise – this shared understanding of the environment can contribute significantly to the creation of a team spirit.
A related notionis that of enculturation: that is, the process of becoming an accepted member of the group, or an insider. This has less to do with expertise and knowledge than learning the unspoken rules and norms of a community. Although becoming a member of a community has much to do with social interactions within the workplace, there is more: a lot of essential know-how and know-what is transferred through informal interactions between senior members of the team (who are often senior members of the organisation) and others.
Projects generally need to draw upon a range of organizational resources: people and physical infrastructure being the most obvious ones. Grabher notes that the increasing projectisation of organizations can be attributed to a perception that project-based management is an efficient way to allocate productive resources in a flexible manner (…whether this perception is correct, is another matter altogether). However, there are other less obvious influences that organisations exert too. For example, Grabher points out that organizational norms and rules provide the basis for the emergence of swift trust, which is trust based on roles and professional ability rather than individuals and personalities. Further, at a higher level, organizational culture plays a role in determining how a project is governed, managed and run. These explicit and implicit norms have a stabilising influence on projects.
In addition to the stabilizing influence of the hosting organisation, projects also offer opportunities to build and enhance links between organisations – for instance, strategic partnerships. This is, in effect, institution building aimed at leveraging the strengths of the participating organisations for a greater joint benefit. In such situations the participating organisations take on the role of “lynchpins” on whom trust is focused.
Grabher makes the point that firms (and institutions comprised of firms) not only provide resources that make projects possible, but also host a range of processes that are needed to organize and run projects. For one, projects are usually preceded by several organisational processes involving deliberation, selection and preparation. These activities have to occur for a project to happen, but they normally fall outside the purview of the project.
A somewhat paradoxical aspect of projects is although they offer the opportunity for enhancing organizational knowledge, this rarely happens in practice. The high pressure environment in projects leaves little time for formal training or informal learning, or even to capture knowledge in documents. To a large extent the hosting organisations are to blame: Grabher suggests that this paradox is a consequence of the lack of organizational redundancy in project-based organizing.
I’ll end this section with the observation that the social dimension of projects is often neglected. Projects are often hindered by organizational politics and inertia. Further, a large number of projects fail because of varying perceptions of project goals and the rationale behind them. Although it seems obvious that a project should not proceed unless all stakeholders have a shared understanding of objectives and the reasons for them, it is surprising how many projects drift along without it. Many project planners neglect this issue, and it invariably comes back to bite them.
Conclusions
In the conclusion to the paper, Grabher states:
The formation and operation of projects essentially relies on a societal infrastructure which is built on and around networks, localities, institutions and firms. Relations between temporary and permanent systems are not a matter of straightforward substitution but have to be regarded in terms of interdependence. ‘Cool’ projects, indeed, rely on ‘boring’ institutions…
This is unarguable, but it should also be kept in mind that projects are often subject to negative organisational influences which can slow them down, or even kill them altogether (which is perhaps why those early defence projects were set up as near-autonomous initiatives). So although it is true that projects are made possible and sustained by the organisations they’re embedded in, they are sometimes hindered by those very organisations .
To sum up in a line: Projects depend on organisations not only for material and human resources, but also draw sustenance from (and are affected by) the social environment and culture that exists within those organisations.
Relational factors in managing outsourced projects
Introduction
More often than not the success of an offshored IT initiative is measured using financial or operational metrics – client-side managers tend to focus on cost savings and vendor-side managers on achieving service level metrics. This is fine as it goes, but is a limited view of the business arrangement. It is far more important for both parties to to focus on building trust and commitment to a long-term relationship. In a paper entitled, Evaluating the Success in International Sourcing of Information Technology Projects: The Need for a Relational Client-Vendor Approach, Peter Haried and K. Ramamurthy look into the role of relational factors in internationally sourced projects. This post is a summary and review of the paper.
Project management methodologies and standards focus on the economic, contractual and operational aspects of projects; they have very little to say about how client-vendor relationships should be managed. Perhaps as a consequence, much of the research on offshored projects is based on agency theory or transaction cost economics, both of which focus on risk and opportunistic behaviour from perspective of clients (rather than vendors). However, it is clear that vendors would generally have a different view of what constitutes risk or opportunism – a risk for a client is not necessarily one for the vendor. Further, as Haried and Ramamurthy mention in their introduction, success is in the eye of the beholder; clients and vendors will differ on what constitutes success. This suggest that a view which emphasizes relationships rather than contracts and SLAs may provide a basis for a more inclusive approach to offshored initiatives.
Recent research has begun to look at the relational aspect of offshoring (see this paper or this one, for example). According to Haried and Ramamurthy, however, little work has been done on integrating the relationship perspective with the traditional outcome-focused view. Their work is an attempt to bridge this gap.
Theoretical Background
In a post entitled, To outsource or not to outsource, I discussed how transaction cost theory can provide organisations an insight into whether or not they should outsource work. According to transaction cost theory, the cost of completing a transaction (from the client perspective) depends critically on:
- The complexity of the transaction: for example, implementing an ERP system is more complex than implementing a new contract management application.
- Whether or not it involves assets that are worth more within a relationship between two parties than outside of it: for example, custom IT services, tailored to the requirements of a specific company have more value to the two parties – provider and client – than to anyone else. This is called asset specificity in economic theory.
These factors can help determine whether or not an organisation should outsource their work, but they neglect the social-relational aspects of the outsourcing relationship. For instance, if the relationship is strong, a firm may feel confident enough to offshore highly complex, organisation-specific work. Clearly, the relational aspect needs to be factored into in any offshoring decision.
The relational view is founded on the assumption that the relationship between the client and vendor is more important for success than a purely economic view. Haried and Ramamurthy use social exchange theory as the basis for their investigation. Quoting from Wikipedia, “Social exchange theory posits that all human relationships are formed by the use of a subjective cost-benefit analysis and the comparison of alternatives.” As such, it assumes that human relationships are based on an economic analysis, albeit a subjective one.
Research Model
Based on a survey of research literature, Haried and Ramamurthy identify the following as key variables that affect offshoring relationships:
- Information Sharing: this defines the degree to which the parties agree to share relevant information with each other. This is really just another term for effective communication, one of the key success factors of any project.
- Legal bonds: these are the legally binding agreements that are set out in the offshoring contract. The authors contend that many problems in offshoring deals can be traced back to the contract between the client and vendor. It is important for both parties to realise that the contracts are necessarily incomplete, and must be interpreted in a far-sighted manner.
- Client adaptations: adaptations made by the client to fit the processes and procedures of the vendor.
- Vendor adaptations: adaptations made by the vendor to fit the processes and procedures of the client.
- Mutual obligations: beliefs that each party hold about their obligations to each other. These generally refer to items that have not been (or could not be) contractualised. Mutual obligations are a form of psychological contract.
- Intercultural competence: The ability to develop good interpersonal and working relationships with people from other cultures, and to resolve any conflicts or misunderstandings that may arise due to cultural differences. Traditionally, intercultural differences have been viewed as a major obstacle in international sourcing arrangements. However, research seems to be somewhat equivocal on this point.
In my opinion, the selection of these factors is arbitrary: the authors do not offer any justification for choosing these six factors rather than others. For example, anecdotal evidence suggests that offshoring clients often complain about the high turnover of vendor staff -the rationale being that it becomes difficult to build good working relationships when key contacts on the vendor-side change often. Given this, continuity (of relahionships) could have been considered a separate variable in much the same way as information sharing has been factored out of mutual obligations (information sharing is a mutual obligation). Although this is just an example, it begs the question as to which other important relational variables might have been omitted from the study.
Haried and Ramamurthy identify the following factors as being measures of the relational success of an offshoring arrangement. In their model these factors are assumed to be caused (or driven) by the above mentioned variables.
- Trust: In most cases the client and vendor are located in different countries, so there’s plenty of scope for (negative) opportunistic behaviour on both sides. Given this, it is important that the two parties trust each other. As such, the degree of trust developed is a good measure of the relational success of a project.
- Commitment: This refers to the effort that each side is willing to put in to maintaining the relationship. Very often this entails going beyond the contract. The ideal situation as far as commitment is concerned is when both parties have an exclusive arrangement to work with each other. Clearly, the degree of commitment is another measure of relational success. However, it isn’t clear to me that it is an independent factor because commitment depends on trust.
- Conflict: All relationships are prone to conflict, outsourcing arrangements are no exception. However, working through and resolving conflicts in a mutually acceptable manner can strengthen the relationship. Conflict can be quantified (sort of) via the overall level of disagreement between the two parties over matters such as goals, procedures, timelines etc. Clearly, the level of conflict is also a good measure of the relational success of the offshoring arrangement.
Again, these three success factors are chosen without justification, omitting other possibly significant ones. For example, longevity of the relationship might also be a good indicator of the success of the relationship. Further, the causal connection between variables and success factors is far from clear; the authors hypothesise a cause-effect relationship between the six relational dimensions and the three measures, but there is no justification offered.
Research Methodology
The authors gathered qualitative data through interviewing a number of offshoring client/vendor pairs about the relational aspects of the outsourcing arrangement. Vendors were contacted through the client – this is an important point which I’ll return to later. The clients were asked to provide information on two projects – one that had been completed recently and the other ongoing. The authors asked for permission to interview multiple stakeholders from both the client and vendor organisations. This provided diverse perspectives on the all questions that were asked. The questions asked pertained to the model discussed in the previous section, in the context of the project that the interviewees had worked on. The questions were open-ended so the interviewees had to think through their answers, not just tick a box.
The authors surveyed five US-headquartered firms from the areas of financial service and manufacturing. These were the clients. The outsourcing partners (vendors) – six in all – are all India-based outsourcing majors. The gathered data covered eight projects across the surveyed organisations.
Analysis
Below are the conclusions the authors drew from an analysis of their data. The findings are listed by each of the model variables.
Information exchange
Client Perspective
Most of the client-side interviewees indicated that communication (information exchange) was a key determinant of the success of the relationship. In many projects the vendor had a on-site team with whom client-side stakeholders could communicate directly. This was highlighted by clients as being an effective means to communicate. It placed the onus of communicating with the offshore team on the on-site vendor team.
Vendor Perspective
The vendor perspective matched that of the client. All vendors agreed that having an onsite team is critical to the success of the project. Although some of the reasons offered by vendor-side stakeholders differed in detail from that of those on the client-side, this indicates that communication is indeed a key relational success factor.
Based on the above, the authors formulate the following proposition:
Proposition 1: Intense, open, and timely information exchange is crucial for relational success for both client and vendor stakeholders.
Vendor Adaptations
Client Perspective
Clients viewed adaptations made by the vendor as critical to the success of the outsourcing relationship. Typically, the adaptations cited by clients included, working hours, processes and procedures, investments made in training staff and placing personnel on site.
Vendor Perspective
Most vendor-side interviewees agreed that the vendor needed to adapt to the client rather than the other way round. Further, many vendors recognized that this was a key to continuing the relationship. As one vendor-side analyst put it, “Up to a certain level, no matter what, we will accommodate because they know if we do not accommodate we will be out.”
The authors point out that these findings are consistent with transaction cost theory in that vendor adaptations are, in effect, a type of asset specificity. They give the vendor an advantage over other vendors who may want to compete for the client’s business because they indicate that the vendor is serious about maintaining and enhancing the relationship with the client.
Based on the above, the authors hypothesise the following:
Proposition 2. Adaptations by vendors are vital for relational sourcing success evaluations by client and vendor stakeholders. These are even more important for client stakeholders than for vendor stakeholders.
I’m not sure I agree with the statement, “[vendor adaptations are] even more important for client stakeholders than for vendor stakeholders”. I’d say they’re at least equally important to vendors because the client could walk away from the relationship if the vendor is not willing to make adaptations.
Client Adaptations
Client Perspective
The responses here were a bit mixed. Clients-side managers believed that some adaptations would have to be made, and were worthy of making too. For example, one manager stated that offshoring would entail more rigorous documentation and adherence to internal processes– which he perceived as a Good Thing. On the other hand, one of the business analyst’s interviewed thought it odd that they (the client) should be making adaptations when they were the customer in the relationship. The perception seemed to be that the vendor should make adaptations, not the client.
Vendor Perspective
Some vendor-side interviewees indicated that clients would need to make adaptations to get the most out of offshoring. Two areas singled out were: 1) adjusting to distributed teams and 2) adapting to cultural differences. That said, vendors valued whatever adaptations their clients made, and realised that these adaptations indicated the seriousness of the client about the relationship.
Based on their findings, the authors propose the following regarding client-side adaptations:
Proposition 3. Adaptations by clients are essential for relational sourcing success evaluations by client and vendor stakeholders. These are even more important for vendor stakeholders than for client stakeholders.
Legal Bonds
Client Perspective
Most client stakeholders considered the offshoring contract to be of limited importance. In most cases, clients viewed the contract as a basis for the relationship, but not a comprehensive document containing last detail of the business agreement. Client-side managers emphasized that the contract was intended to be flexible.
Vendor Perspective
The vendor, quite naturally, placed more emphasis on the contract. That said, most vendor managers noted that the contract described only the high-level goals, not how they would be achieved. Most vendors saw the contract as a means to engender trust and reduce conflict. Based on interviewee responses, the authors make the following hypothesis:
Proposition 4. Legal bonds are considered key to relational sourcing success for vendor stakeholders to a greater degree than for client stakeholders.
Although the authors claim that these findings are consistent with social exchange theory, I suspect that the respondents may have glossed over difficulties – see my post on some pitfalls of contracts for more on why.
Mutual Obligations
Client Perspective
Many clients did not acknowledge that mutual obligations played a role in the relationship. However, some client-side stakeholders acknowledged that many vendor personnel went above and beyond the call of duty (and the contract). On the other hand, some senior managers felt they weren’t getting value for the large sums money they were spending.
Vendor Perspective
Vendor stakeholders were consistent in their belief that the contract could not capture everything, and that mutual obligations were an important determinant of the success of the relationship. Many vendor-side personnel claimed that they were doing several tasks that were not in the contract.
The authors suggest that the differences in perceptions of mutual obligations may be because many client-side personnel were simply not aware of what was written in the contract. In contrast, most vendor stakeholders had a good idea of what was contracted. Based on this, the authors make the following hypothesis:
Proposition 5. Mutual obligations are viewed by vendor stakeholders as essential for relational sourcing success, but not necessarily by client stakeholders.
Intercultural Competence
Client Perspective
Clients acknowledged the importance of intercultural understanding to the success of the relationship. However, most clients displayed a good awareness of cultural differences and what needed to be done to address issues arising from them.
Vendor Perspective
Like clients, all vendors acknowledged the importance of cultural differences. Like clients, they did not believe these presented any major problems.
The authors emphasise that their findings are not consistent with previous research (see this paper for example). Based on their findings they propose the following:
Proposition 6. Intercultural competence is not a key determinant of relational sourcing success valuations by client and vendor stakeholders.
Summary results and conclusions
Based on their findings, the authors make the following points:
- Success of the relationship depends on many factors (in particular, those listed above), and any analysis must include both client and vendor perspectives. Many earlier studies included only the client perspective.
- Information exchange (communication) is acknowledged as a key factor by both clients and vendors.
- The clients expected vendors to make adaptations to the clients’ processes, but did not necessarily believe that they (the clients) needed to make any adaptations. The authors point out that this finding is inconsistent with transaction cost theory
- Clients did not always acknowledge the importance of contract, but the vendor always did. The same was true of the role of mutual obligations. The authors speculate that this may be because client stakeholders weren’t always aware of what was contracted whereas vendor stakeholders invariably were.
- Neither clients or vendors believed that cultural differences were an unmanageable issue. The authors suggest that this may be because offshoring is now a well-accepted practice and that client firms have a better understanding of the potential problems that intercultural issues can cause.
- They acknowledge the limitations of their research: sample size, location of clients and vendors. However, they do not acknowledge that clients and (especially!) vendors may not have been open in their responses. This is a particular concern because vendors were contacted through the client.
- They believe that their work may be useful to project managers who work on internationally sourced projects because it provides a set of key relationship dimensions that managers should focus on. Maybe so, but readers should be aware that there could be other key dimensions as I’ve noted earlier in the review.
To conclude: although the conceptual model presented by the authors has some shortcomings, project managers will find the paper a worthwhile read because it highlights the importance of relational factors in managing outsourced projects.
