What's changed: Initial version (chapter 5, s1-s5)
5.3Project Management
Learn, on the foundation of the PMBOK body of knowledge, scope management via the WBS (work breakdown structure), schedule management via arrow diagrams, PERT, and the critical path, cost management via EVM (earned value management), and the management areas of quality, risk, and stakeholders.
Completing a project as planned requires the skill of quantitatively managing what to build, when it must finish, and how much it will cost. Among the body of knowledge that PMBOK organizes, the calculation-heavy areas of scope, schedule, and cost are especially important and carry into the Applied Information Technology exam--reading arrow diagrams and calculating EVM metrics are must-master skills.
5.3.1PMBOK and WBS
- PMBOK (Project Management Body of Knowledge) is an internationally recognized standard guide that systematizes project management knowledge. It is organized into multiple knowledge areas--scope, schedule, cost, quality, risk, stakeholders, and more--and forms the foundation for many project management methods and certifications.
- WBS (Work Breakdown Structure) is the technique of hierarchically decomposing a project's deliverables and work into manageable units (work packages). It is used to exhaustively surface the scope (the range of work the project will perform) and serves as the basis for estimation, progress tracking, and staff assignment. Decomposing too far raises management overhead, so stopping at an appropriate level of granularity matters.
