Profiling a project correctly requires a system that is relatively easy to use but that includes enough attributes to capture all the most important characteristics of a complex project. The Darnall-Preston Complexity Index (DPCI™) achieves this objective by grouping eleven attributes into four broad categories: internal attributes, external attributes, technological complexity, and environmental attributes.
Projects are more likely to fail in the beginning, not in the end. This generalized statement reflects the importance of understanding the environment in which a project will be executed and the importance of developing an execution plan that can be successfully implemented within this environment. Recovery costs can be extremely high for projects where the environment is misread or the execution plan does not address critical issues of the project environment. In addition to cost overruns and delays in the project, execution plans that are not aligned with the project environment can create barriers that make recovery difficult, and in some cases, the business purpose of the project cannot be met. The DPCI is a tool to assist project stakeholders in developing a comprehensive analysis of the project environment and a project execution plan more aligned with that environment. Understanding and aligning a project with the project’s environment increase the likelihood of achieving project success.
The foundation of a sound project execution plan is an assessment of the project environment. This assessment provides the information on which the execution plan is built. In the absence of an accurate assessment of the project environment, the project leadership makes assumptions and develops the execution plan around those assumptions. The quantity and quality of those assumptions will significantly influence the effectiveness of the project execution plan. The amount of information available to the project manager will increase over time and assumptions will be replaced with better information and better estimates. As better tools are developed for evaluating the project environment, better information will become available to the project manager.
The project environment includes all the conditions that can influence the outcome or success of the project. Project size, technological complexity, cultural and language barriers, the political landscape, and resource constraints are some of the components of the project environment that can influence the project success. Understanding these influences and developing a project profile creates a foundation for building an effective project execution plan.
The DPCI is one model for understanding and profiling projects. This index assesses the complexity level of key components of a project and produces a unique project profile. The profile indicates the project complexity level, which provides a benchmark for comparing projects and provides information about the characteristics of a project that can then be addressed in the project execution plan.
The DPCI provides project stakeholders with information about the project to define the experience, knowledge, skills, and abilities needed by the project manager. The DPCI also has implications for the composition, organization, and skills needed by the project leadership team. The DPCI provides information and a context for developing the project execution plan and for assessing the probability of success.
KEY TAKEAWAYS
- Complex systems have many different parts that interact with each other in different and often unpredictable ways. They adapt to changes in their external and internal environments.
- The Darnall-Preston Complexity Index (DPCI) groups project attributes into four categories: external attributes, internal attributes, technological complexity, and environmental attributes.
