2 – ORGANIZATIONAL INFLUENCES AND PROJECT LIFE CYCLE
There is no single ideal structure that will apply to all projects. Although industry common practices will often lead to the use of a preferred structure, projects in the same industry—or even in
the same organization—may have significant variation. Some will have only one phase, as shown in Figure 2-10. Other projects may have two or more phases.

Figure 2-10. Example of a Single-Phase Project Some organizations have established policies that standardize all projects, while others allow the project team to choose and tailor the most
appropriate approach for their individual project. For instance, one organization may treat a feasibility study as routine pre-project work, another may treat it as the first phase of a project,
and a third may treat the feasibility study as a separate, stand-alone project. Likewise, one project team may divide a project into two phases whereas another project team may choose to
manage all the work as a single phase. Much depends on the nature of the specific project and the style of the project team or organization.
2.4.2.1 Phase-to-Phase Relationships
When projects have more than one phase, the phases are part of a generally sequential process designed to ensure proper control of the project and attain the desired product, service, or
result. However, there are situations when a project might benefit from overlapping or concurrent phases. There are two basic types of phase-to-phase relationships: • Sequential relationship.
In a sequential relationship, a phase starts only when the previous phase is complete. Figure 2-11 shows an example of a project with three entirely sequential phases. The stepby-step nature of
this approach reduces uncertainty, but may eliminate options for reducing the overall schedule.
