1 Project Life Cycle

2 Project Life Cycle Project Life Cycle defines or tells:
The phases of the project (time) The work performed in each phase (work) The input and output of each phase (result) The milestone of each phase (end sign) Common Characteristics of Project Life Cycles: Cost and Staffing levels are low at start and move higher towards the end Probability of successfully completing project is low at beginning, higher towards the end as project continues

3 The Project Life Cycle Phases that all projects go through from inception to completion DEFINITION CONCEPTION PLANNING & ORGANISING CLEAN-UP IMPLEMENTATION

4 Project Life Cycle Effort Time Planning & Organizing Implementation

5 Conception Phase Conceptualization is the first stage in the project lifecycle. Conceptualization is the idea, thought, initial plan, first stage of thinking entrepreneur, manager or economic planner about his scheme, plan for elimination the existing problems in the existing operation or avail new opportunities prevailing. The concept may be to set up a new project or to expand the existing operation or modernize, replace with new concepts or technologies and to initiate action for quality of improvements.

6 Definition Phase The definition phase of a system is mainly refinements of the elements described in the conception phase. All the sub-systems and elements of the proposed system are scrutinized as defined. Fabrication of final system performance requirements Preparing detailed plans Estimating cost, schedule, and performance Spotting areas of high risks Identify and prepare the documents required to system, such as procedures, documents, budgets and finance

7 Planning Phase Core Planning Scope Planning – written statement
Scope Definition – subdividing major deliverables into more manageable units Activity Definition – determine specific tasks needed to produce project deliverables Activity Sequencing – plotting dependencies Activity Duration Estimating – determine amount of work needed to complete the activities (continued)

8 Planning Phase Core Planning
Schedule Development – analyze activity sequences, duration, and resource requirements Resource Planning – identify what and how many resources are needed to perform the activities Cost Estimating – develop resource and total project costs Cost Budgeting – allocating project estimates to individual work items Project Plan Development – taking results from other planning processes into a collective document

9 Planning Phase Facilitating (Planning) Processes
Quality Planning – standards that are relevant to the project and determining how to meet standards Organizational Planning – identify, document, and assigning project roles and responsibilities Staff Acquisition – obtaining the human resources Communications Planning – determining rules and reporting methods to stakeholders (continued)

10 Planning Phase The order of planning events : Scope Statement
Create Project Team Work Breakdown Structure Finalize the team Network Diagram Estimate Time and Cost Critical Path Schedule Budget (continued)

11 Planning Phase The order of planning events (continued) Purchase Plan
Quality Plan Risk Identification, quantification and response development Change Control Plan Communication Plan Management Plan Final Project Plan Project Plan Approval

12 Implementation Phase (continued)
Project Plan Execution – performing the activities Complete Work Packages Information Distribution Scope Verification – acceptance of project scope Quality Assurance – evaluating overall project performance on a regular basis; meeting standards Team Development – developing team and individual skill sets to enhance the project Progress Meetings (continued)

13 Implementation Phase Information Distribution – making project information available in a timely manner Source Selection – choosing appropriate suppliers Contract Administration – managing vendor relationships

14 Controlling Phase To regularly measure project performance and to adjust project plan Take preventive actions in anticipation of possible problems Overall Change Control – coordinating changes across the entire project plan Scope Change Control – controlling “scope creep” Schedule Control – adjusting time and project schedule of activities (continued)

15 Controlling Phase Cost Control – managing project budget
Quality Control – monitoring standards and specific project results; eliminating causes of unsatisfactory performance Performance Reporting – status, forecasting, and progress reporting schedule Risk Response Control – responding to changes in risk during the duration of the project

16 Clean-up Phase Administrative Closure – generating necessary information to formally recognize phase or project completion Contract Close-out – completion and delivery of project deliverables and resolving open issues Purchase Audits Product Verification Formal Acceptance Lessons Learned Update Records Archive Records Release Team
