Like waterfall, this includes developing repeatable processes for disciplines such as communications, governance, change control, risk and issue management, etc. Planning occurs continuously, though at a high level in the beginning of the project, to form a prioritized framework for what the project team sets out to achieve. Over the course of project execution, project variances identified must go through governance channels for analysis and approval prior to implementation significant changes may require project re-planning efforts.Īgile places more emphasis on the ability of the project team to react to change. For a period of time, prior to any system development activities, the project team documents the processes, procedures, and controls that will be carried out during the project that are intended to ensure that the entire project scope is delivered on time and within budget. Project management for waterfall requires detailed planning that begins after project initiation with the development of the Project Charter. Project management planning practices also vary between waterfall and agile, with the biggest difference being the depth and timing of project management activities. Another aspect of scope flexibility allows the project team to make the decision to shift delivery of functionality from iteration to iteration, as long as core or critical functionality is delivered before the project ends. Design features or functional elements that are not deemed core or critical to the project are flexible and are dependent upon the amount of time and resources available for the project. With time and resources being constant, scope that is not core or critical to achieving the project outcomes become the constraint that is most negotiable. Agile projects commit to delivering project outcomes within a fixed time frame with fixed resources. As the project goes through the development phases and new information identified necessitates a change to the scope, the project goes through a structured change control process and resources and time are adjusted accordingly.Īs shown in Figure 1-1, agile places emphasis on resources and time over scope. Resource and time estimates are generated based on the fixed scope and are tracked and managed throughout the project. With waterfall projects, requirements are developed and thoroughly documented in project planning in order to come up with a fixed scope.

To better describe the ends of this spectrum, the following sections will compare and contrast key characteristics of agile with the more familiar aspects of waterfall. There is a spectrum of project management and system development approaches available for projects to choose from, anchored on either ends by the predictive waterfall approach and the adaptive agile approach.
