PROJECT LIFE CYCLE






This is the collection of the sequential, overlapping and parallel project phases whose names and numbers are determined by the management and control the needs of the project.
The life cycle structure involves:
• Starting the project (Initiating)
• Organizing and Preparing (Planning)
• Carrying out the project work (Executing, Monitoring &Control)
• Closing the project

PROJECT PHASES
These are divisions within major deliverable where extra control is needed to effectively manage the completion of major deliverable. They help to achieve the primary deliverables for easy management, planning and control. The number of phases depends on the size, complexity and impact of the project.





Taking an example #1 of constructing a 2nd floor building:

Phase 1: Foundation stage: Design and planning, construction of ground floor
Phase 2: Construction of the 1st and 2nd floors
Phase 3: Plumbing
Phase 4: Electrical Installation
Phase 5: Finishing etc

Another example as #2 of electrical project in the village:

Phase 1: Introduction
Phase 2: Awareness and marketing
Phase 3: Surveying
Phase 4: Customer signups
Phase 5: Customer connections etc

Phase to Phase Relationship:

1. Sequential relationship whereby a phase starts only when the previous phase completes.
2. Overlapping relationship whereby a phase starts prior to completion of the previous phase.
3. Parallel relationship whereby two or more phases start at one time.



Phase Review is the process of reassessing the point (both the deliverable and project performance) to determine if

• The project can proceed on the next phase
• The project needs some corrections after detecting errors
For instance if it happens that one of the phases projects a greater risk of the project, then the phase can be closed to stop initiating other phases.

NOTE: Project life cycle can be:

• Predictive or plan-driven (meaning that the project whose scope, time and cost can be determined earlier, the product to be delivered is well understood and everything is planned). For example, construction projects
• Iterative and incremental (meaning that the project activities are repeated intentionally to increase the understanding of the project and add functionality of the product). For example, design projects
• Adaptive or change-driven (meaning that the project is responding to a change of environment and stakeholders’ involvement when scope and requirements are hard to be defined in advance). For example, Software projects
