Process Decision Program Chart (PDPC) P. 177

Tree diagram that identify all events (first three levels) that can go wrong (fourth level) and the appropriate countermeasures for these events (fifth level).

Often used when a plan is large and complex, must be on schedule, is being implemented for the first, and the cost of failing is high.


Interrelationship Digraph (ID) P. 179

Tools that displays the cause-and-effect relationships between ideas of factors in a complex situation.

AKA: relations diagram, circle diagram or hand-off map.


Affinity Diagrams P. 181

Tool used to organize information and help achieve order out of the chaos that can develop in a brainstorming session.


Tree Diagrams P. 183

Tools that depicts the hierarchy of tasks and subtasks needed to complete an objective.


Matrix Diagram P. 186

Tool that identifies the relationships that exist between groups of data, or strength of those relationship as well.


Matrix Shape P. 186

C: Cube. Three dimensional (3 variables)
L: Most basic /common matrix format (2)
T: T-shape (3)
X: Extends the T into and X-shape (4)
Y: Shows relationship between variables (3)
Roof: Used with L or T matrix to show one groups of items relating to itself (1)


Prioritization Matrix P. 191

Tool used to choose between several options that have many useful benefits, but where not all of them are of equal value.


Developing Prioritization Matrix

-Create L-matrix with 1. relative importance weightings (sum 100%), 2. criteria, 3. options.
-Rank each option within a criterion, If equal use standard rank averaging.
-Create another prioritization matrix and cross-multiply for each option.
-Select the option with highest row total
-Conduct a sanity check to ensure the solution makes sense.


Activity Network Diagram P. 194

Tool used to illustrate a sequence of events or activities (nodes) and the inter-connectivity of such nodes.

Earliest Start = The largest EF leading into (before) this one
Latest Finish = The smallest LS following (after) this one.

Total Slack (whole project schedule) = LS- ES or LF- EF
Free Slack (next jobs) = Smallest ES after this one- EF
