  1. Project Management Quadruple Constraint Jeffrey P. Landry, Ph.D.

  2. Project • Defined: “A temporary endeavor undertaken to create a unique product or service.”* • IS project: A temporary endeavor to develop or enhance an information system * Project Management Institute, Inc. A Guide to Project Management Body of Knowledge ISC-565

  3. Characteristics of Projects • Unique purpose (eg. to build or enhance an IS) • Temporary • Requires resources • Has a primary sponsor (customer) • Involves uncertainty (and unpredictability?) ISC-565

  4. Four Dimensions of Projects • Scope • Time • Cost • Quality ISC-565

  5. Quadruple Constraint Scope Quality Time Cost ISC-565

  6. Quadruple Constraint • A change in one dimension affects one or more of the others • Increasing scope increases both time and cost • Cutting quality reduced cost and time • Increasing cost decreases time ISC-565

  7. Quadruple Constraint • Deals with core areas of project performance • Each dimension is measurable • Project success and failure in terms of these dimensions ISC-565

  8. Brooks’ Law • Adding workers to a late project makes it later • Recognizes that adding new people to a project creates • The need for training and learning • Additional communication paths ISC-565

  9. Abdel-Hamid • Found that Brooks’ Law had a caveat • Increasing cost (adding people) early enough can reduce time • Adding more people to quality assurance activities has a greater impact on time while not sacrificing quality goals ISC-565
