4) capture the central thought or theme that each grouping of ideas represents and write this on a bigger sticky note (of different color, if possible), which will serve as the header card of the grouping; the central theme should be arrived at through consensus; post each header card at the top of the group it represents;

5) draw the final affinity diagram (see Figure 2); the problem or issue statement should be in a large box at the top of the diagram; the groupings of ideas must be below this problem statement box; the ideas in each grouping must be clustered within a box that is topped by the header card.

What steps and considerations are involved in setting up an early life failure monitor?

Analyze why an ELF Monitor needs to be set up

Define how the ELF Monitor will be implemented to meet its purpose

Define the manpower and logistical requirements of the ELF Monitor

Assess the costs of setting up and sustaining the ELF Monitor

15) the actual purpose of the ELF monitor

10) how the ELF monitor will integrate into the over-all Rel program of the company

13) what kind of data the ELF monitor must generate

4) failure mechanisms of interest

8) customer returns being received (that need to be prevented)

6) over-all procedure for the ELF monitor

7) components of a basic ELF monitor

18) procedures and rel tests needed for each component of the ELF monitor

21) reporting of the ELF monitor data

22) metrics for the ELF monitor

23) ownership for the ELF monitor

1) equipment needed

2) manpower available

3) equipment available

5) in-house reliability testing capability

9) failure analysis support for the monitor

24) test support for the ELF monitor

17) the utilities required by the monitor

16) the consummables needed for the monitor

12) levels of expertise of personnel

14) training needed for the personnel

11) cost of any new equipment needed

19) capital expense budget approved for the monitor

20) cost of sustaining the monitor per quarter

Figure 2. A Simple Affinity Diagram for the Problem Stated in Figure 1

In the affinity diagram above, the ideas were grouped into four general steps that need to be followed in order to understand what it takes to set up an ELF Monitor. These steps (the central themes of the groupings) were shown in the gray cells of the table, which represent the header cards of an actual affinity diagram construction session.
