There are about a dozen quality theorists that you should be familiar with as far as the PMP exam is concerned. I have listed them down here along with the key things you should know about them for the exam.
- McLelland: Theory of Needs; States that people are motivated either by achievement, affiliation or power.
- Vroom: Expectancy Theory; People are motivated by positive outcomes, and expected rewards.
- Fledler: Contingency Theory; Leaders should adapt their management style to the situation.
- Ouchi: Theory Z; Provide a job for life for increasing employee loyalty.
- Tuckman: Tuckman’s Ladder; Forming, Storming, Norming and Performing.
- Juran: Quality by Design
- McGregor: Theory X and Y. X is people are lazy, and need to be micromanaged. Y is people are motivated, and need to be given more responsibility.
- Herzberg: Hygiene Theory; Hygiene factors (e.g. status, job security, salary, fringe benefits, work conditions, good pay, paid insurance, vacations) that do not give positive satisfaction or lead to higher motivation, though dissatisfaction results from their absence. The term “hygiene” is used in the sense that these are maintenance factors.
- Maslow: Hierarchy; People can only ascend to higher levels after fulfilling lower level needs.
- Deming: Plan-Do-Check-Act Cycle, Quality is management’s responsibility.
- Philip Crosby: Zero Defects: identify processes to remove defects, quality is built in to the processes
- Pareto: Pareto Principle – 80/20 Rule
- Ishikawa: Fishbone Diagram
I made flashcards for these as well which are a useful way to memorize this.
