Project Life Cycle and Project Phases Part 1

 Phase is collection of logically related project activities that culminate in the completion of one or more deliverables

every project is made up of one or more phases

A system to ensure Project work get performed at right time and sequence

eg : ERP,MS projects, Files etc

•  Executes one phase at a time
•  More time taking , as each phase wait for previous to complete
•  Eg : Phase 2 after completion of phase 1

• Phases will not wait for previous one to complete
• Saves time but need more care
• More risky and prone to error

• Starting the project
• Organizing and preparing
• Carrying out the work
• Ending the project

• Predictive
• Iterative
• Incremental
• Adaptive
• Hybrid

• Water flow model ,fully plan driven
• Definite and accurate life cycle and takes more time
• Time and cost are determined at the early stage of life cycle

• Only scope is determined early
• Time and cost updated constantly through the life cycle
• Series of iterations are done, each iteration will have all the phases done on previous iteration
• Gets chance to better define requirement on start of each cycle

• develops a product through the implementation of incremental steps
• each increment have which have predetermined timeframes
• each increment  delivers additional functionality for the product 
• customers sign off at each exit point

• rapid development process (like agile) to execute a project fast
• good when you are developing a first of its kind application
• The customer must be intimately involved in the process
• must be able to define incremental requirements at the start of each iteration

1. Combination of predictive and Adaptive approach
2. accept the fluidity of projects and allow for a more nimble
3. and nuanced approach to work
