Checklists
Checklists are used to determine how often an
event occurs over a designated period of time. Information may be
collected either for events as they happen or for events that have
already occurred.
Although the purpose of a checklist is to track data - not analyse it, checklists often help to indicate what the problem is.
Common items noted on checklist are;
- Number of times something takes place,
- Length of time it takes to get something done,
- Cost of a certain operation over a period of time,
- Frequency of Occurrence; by machine, by employee, by location, etc.

The general procedure is:
Step 1 - Design & Plan Collection
Team to agree on what event they are observing
- Decide on what data is to be collected.
- Decide on how long to collect the data for.
- Design the Checklist.
Step 2 - Organise Collection
- Brief all who have to record the data (perhaps put instructions on back of Checklists)
- Collect the information honestly and consistently
Step 3 - Collate & Analyse
- using Pareto or graphs etc.
