Transcript

  • 1. Seven Management and Planning Tools 1 Seven Management and Planning Tools The Seven Management and Planning Tools have their roots in Operations Research work done after World War II and the Japanese Total Quality Control (TQC) research. In 1979 the book Seven New Quality Tools for Managers and Staff was published and in 1983 was translated into English. The seven tools include: 1. Affinity Diagram (KJ Method) 2. Interrelationship Diagraph (ID) 3. Tree Diagram 4. Prioritization Matrix 5. Matrix Diagram 6. Process Decision Program Chart (PDPC) 7. Activity Network Diagram The seven tools Affinity Diagram This tool takes large amounts of disorganized data and information and enables one to organize it into groupings based on natural relationships. It was created in the 1960s by Japanese anthropologist Jiro Kawakita. Its also known as KJ diagram,after Jiro Kawakita. Affinity diagram is a special kind of brainstorming tool. Interrelationship Diagraph This tool displays all the interrelated cause-and-effect relationships and factors involved in a complex problem and describes desired outcomes. The process of creating an interrelationship diagraph helps a group analyze the natural links between different aspects of a complex situation.
  • 2. Seven Management and Planning Tools 2 Tree Diagram This tool is used to break down broad categories into finer and finer levels of detail. It can map levels of details of tasks that are required to accomplish a goal or task. It can be used to break down broad general subjects into finer and finer levels of detail. Developing the tree diagram helps one move their thinking from generalities to specifics. Prioritization Matrix This tool is used to prioritize items and describe them in terms of weighted criteria. It uses a combination of tree and matrix diagramming techniques to do a pair-wise evaluation of items and to narrow down options to the most desired or most effective. Matrix Diagram This tool shows the relationship between items. At each intersection a relationship is either absent or present. It then gives information about the relationship, such as its strength, the roles played by various individuals or measurements. Six differently shaped matrices are possible: L, T, Y, X, C, R and roof-shaped, depending on how many groups must be compared. Process Decision Program Chart (PDPC) A useful way of planning is to break down tasks into a hierarchy, using a Tree Diagram. The PDPC extends the tree diagram a couple of levels to identify risks and countermeasures for the bottom level tasks. Different shaped boxes are used to highlight risks and identify possible countermeasures (often shown as clouds to indicate their uncertain nature). The PDPC is similar to the Failure Modes and Effects Analysis (FMEA) in that both identify risks, consequences of failure, and contingency actions; the FMEA also rates relative risk levels for each potential failure point.
  • 3. Seven Management and Planning Tools 3 Activity Network Diagram This tool is used to plan the appropriate sequence or schedule for a set of tasks and related subtasks. It is used when subtasks must occur in parallel. The diagram enables one to determine the critical path (longest sequence of tasks). (See also PERT diagram.) Further reading • Brassard, M.
