The CHAOS study published in 1995 by The Standish Group found that although the U.S spent over $250 billion on IT projects, approximately… 31% were cancelled before completion 53% were completed but over budget, over schedule, and did not meet original specifications. For mid-size companies, average cost overruns were 182%, while average schedule overruns were 202%!สรุปแล้ว Project มูลค่า 1 ล้านเหรียญที่ตั้งใจให้เสร็จใน 1 ปี จะใช้เงินจริง $1,820,000 และใช้เวลา 2 ปี โดยได้ function มาเพียง 65 %
Larger projects have the lowest success rate and appear to be more risky than medium and smaller projectsTechnology, business models and markets change so rapidly that a project that takes more than a year can be obsolete before they are completed.The Chaos study also provides some insight as to the factors that influence project success.

Project Life Cycle (PLC)A collection of logical stages or phases that maps the life of a project from its beginning to its end in order to define, build and deliver the product of the project – i.e., the information systemProjects are divided into phases to increase manageability and reduce riskPhase exits, stage gates, or kill points are decision points at the end of each phase to evaluate performance, correct problems or cancel the projectFast tracking is the overlapping of phases to reduce the project’s scheduleCan be risky!
Represents the sequential phases or stages an information system follows throughout its useful lifeUseful for understanding the development of the project’s largest work product – the application systemPhases/StagesPlanning Analysis Design Implementation Maintenance and Support
The systems development life cycle (SDLC) becomes part of the project life cycle (PLC).The PLC focuses on the project management phases, processes, tools and techniques for effectively managing the project.The SDLC focuses on the software engineering phases, processes, tools and techniques for building and/or implementing the IT solution.
