Brief Description of PI Tools
| Term | Definition |
|---|---|
| Ishikawa diagram | displays cause and effect for contributing causes |
| Gantt chart | timeline project management tool |
| Poka yoke | mistake proofing |
| Kanban method | lean tool for inventory management |
| Kanban method | visual of workflow in order to balance demand w/ capacity & see bottlenecks |
| fishbone | Ishikawa diagram |
| gap analysis | evaluation between current state and future state |
| frequency distribution | used to summarize data into categories |
| control chart | tool used to monitor data over time & visualize process variation |
| Lean | improvement process which targets elimination of waste |
| DMAIC | improvement process which targets eliminating variation |
| flow chart | visual of process steps in sequential order |
| scatter plot | visual of the relationship between 2 variables |
| Pareto chart | helps to prioritize (bars in descending order with a line graph of the cumulative totals) |
| run chart | line graph to display data over time; no control limits |
| force field analysis | lists forces for and against a proposed change |
| mean | average |
| median | midpoint of a ranked order set of data |
| mode | most frequently observed value(s) |
| affinity diagram | used to organize a lot of ideas into clustered groups of like items |
| measures of central tendency | mean, median, mode |
| measures of variability | standard deviation, range, variance |
| FMEA | preventive tool that evaluates processes/equipment for issues in relation to the likelihood of severity, occurrence, and detection |
| Phases of DMAIC | Define - Measure - Analyze - Improve - Control |
| range | difference between the largest and smallest values in a data set |
| standard deviation | average of the deviations from the mean |
| Matrix Diagram | Permits a team to methodically discover and analyze the relationships between 2 or more sets of information. A rating system is used. This visual tool helps a team to reach consensus by providing structure for decision making. |
| Regression Analysis | Statistical procedure to 'predict outcomes' based on how individual variables interact (jointly & individually) with the process being measured |
| Multiple Regression Analysis | Exercise that estimates the effects of 2 or more independent variables (x) on a dependent measure (y) |
| Nominal Group Technique | Group decision-making process for generating many ideas in which each member initially works by him/herself. Also known as brainwriting. |
| Plan-Do-Check-Act | Four-step process designed to continuously improve quality; originally conceived by Shewart |
| Plan-Do-Study-Act | Later adaptation by Deming of the Plan-Do-Check-Act; also referred to as the Deming Cycle or the Deming Wheel |
| Prioritization Matrix | Tools that organizes tasks, issues, or actions and prioritizes them based on agreed-upon criteria. Often displayed in the L-shaped diagram format. |
| SBAR | Evidence-based standardized communication tool; acronym for Situation, Background, Assessment, Recommendation |
| Six Sigma | Improvement methodology that uses statistical analysis & other methods to ELIMINATE DEFECTS and REDUCE VARIATION |
| Spaghetti Diagram | Layout diagram; graphic representation of the flow of traffic or movement. |
| SIPOC | Supplier-Input-Process-Output-Customer … tool used early to provide a broad overview of a process. It identifies key drivers of a process. |
| Tree Diagram | Method that maps out the full range of paths and tasks that are involved in a process; often used in the RCA process to visually display all the causes/process failures related to a specific issue; resembles an organizational chart in appearance. |
