Study Notes
Key Performance Indicators (KPIs)
- A KPI is a metric used to measure progress toward an objective
- It is a measurable performance objective
- Examples of KPIs: capacity, productivity
- KPIs help identify gaps between actual and expected system performance
- KPIs are used to assess system performance and identify problem areas
Identifying Problem Areas
- Analyze process flowcharts and metrics to reveal weaknesses and problem areas
- Look for disconnects in the system or process that make it less effective or efficient
- Disconnects can be an input, step, or output that is missing, unnecessary, or substandard
- Disconnects can occur at the wrong time or as an activity
Brainstorming and Process Improvement
- Break down a complex process into smaller components to identify areas for improvement
- Learn from organizations that have better processes and apply that knowledge to create a new system
- Use a simple tool, the impact-effort matrix, to rate solution options according to impact and effort required
- Plot the options on a chart to compare and prioritize them
Impact-Effort Matrix
- A tool used to choose among options, rating them according to potential impact and effort required
- Options are plotted on a chart with impact on the vertical axis and effort on the horizontal axis
- Quadrants help compare lower-impact, lower-effort options and higher-impact, higher-effort options
Cost-Benefit Analysis
- Calculate the costs and benefits of an improvement project at regular time intervals
- Consider financial costs and benefits, as well as intangible costs and benefits
- Intangible costs and benefits can be difficult to estimate, but should not be ignored
- The payback period or breakeven point is an important consideration, especially for big capital expenditures or borrowing
Theory of Constraints (TOC)
- Developed by Eliyahu M. Goldratt and introduced in his book The Goal (1984)
- The core principle of TOC is that every system is limited by a constraint, which keeps the system from achieving its goal more efficiently or completely
- There may be a few constraints, but not many, and they can be within the system or outside it
