The Project Life Cycle•The project life cycle is the accumulation of all phases in the project –All projects are divided into phases, and all projects, large or small, have a similar life cycle structure.: Starting the project , organizing and preparing , carrying out the project work and closing the project–At a minimum, project will have a beginning or initiation phase, an intermediate phase or phases, and an ending phase.•Each phase has a defined endpoint
Characteristics of Project Life Cycle•Cost and staffing levels are low at the start, peak as the work is carried out, and drop rapidly as the project draws to a close. •Stakeholder influences, risk, and uncertainty, are greatest at the start of the project. These factors decrease over the life of the project. •Ability to influence the final characteristics of the project’s product, without significantly impacting cost, is highest at the start of the project and decreases as the project progresses towards completion. …or…The cost of changes and correcting errorstypically increases substantially as the
Project Phases and the Project Life Cycle•A project life cycle is a collection of project phases that defines:–What work will be performed in each phase–What deliverables will be produced and when–Who is involved in each phase –How management will control and approve work produced in each phase•A deliverable is a product or service produced or provided as part of a project
Handoffs•Project phases evolve through the life cycle in a series of phase sequences called handoffs, or technical transfers. The end of one phase sequence typicallymarks the beginning of the next.
Phase-to-Phase Relationships •There are three basic types of phase–to–phase relationships :–A Sequential relationship : where a phase can only start once the previous phase is complete –An Overlapping relationship : where the phase starts prior to completion of the previous one (Fast tracking). Overlapping phase may increase risk and can result in rework .–An Iterative relationship : where only one phase is planned at any given time and the planning for the next is carried out as work progresses on the current phase and deliverables
Organizational Process Assets•Processes & Procedures–Organizational standard processes such as standards, policies–Standardized guidelines, work instruction, proposal evaluation criteria, and performance measurement criteria–Templates –Financial control procedures–Procedures for prioritizing, approving, and issuing work authorization–Etc.•Corporate Knowledge Base–Process measurement databases–Project files–Historical information & lesson learned knowledge bases–Issue and defect management databases–Configuration management knowledge bases–Financial databases–Etc.
Enterprise Environmental Factors•Refer to both internal & external environmental factors that surround or influence a project’s success•As an input in almost all project management process•May
