PMBOK Overview (nine knowledge systems and five specific stages)

Early project management mainly focused on cost, progress (time), and later expanded to quality. Over the past decade, project management has gradually evolved into a separate branch covering nine major knowledge systems and five specific stages. The nine major knowledge systems include:

In project analysis, project management personnel must integrate and coordinate various capabilities.

Time management requires training of planning skills. Experienced project management personnel should know how to bring the project back to planning when there is a deviation from planning.
Cost management requires the project management personnel to develop business skills, such as cost estimation, planned budget, cost control, capital budget and basic financial settlement.
Human resource management focuses on personnel management capabilities, including conflict handling, employee motivation promotion, efficient organizational structure Planning, team work and team formation, and interpersonal skills.
Risk management requires the management personnel to make decisions when the information is incomplete. The risk management model consists of three steps: risk identification, risk impact analysis, and risk response plan.
Quality management requires project management personnel to be familiar with basic quality management technologies. For example, make and describe the Quality Control Chart, implement rules 80: 20, and try to achieve zero defects.
