ITPEC FE Morning April 2018 Question 75

Collected information grouped by mutual relationship to clarify the problem — that is an affinity diagram (KJ method).

Facts, opinions and ideas are written one per card, cards that feel related are gathered into groups, each group gets a title, and the groups are arranged and linked. The structure that emerges from scattered, verbal information shows what the real problem is. It is one of the seven new QC tools, used when a situation is still vague.

Answer (c)

Why not others:

• •(a) — foreseeing the outcomes as a situation develops and planning the process that leads to the desired result is the PDPC (process decision program chart)
• •(b) — clarifying cause and effect among intertwined, complex factors is the relations diagram
• •(d) — breaking a purpose down step by step into means and measures to find the best one is the tree (systematic) diagram

Key rule: Among the new QC tools, affinity groups vague information, relations links causes, tree breaks goals into means, and PDPC plans for contingencies.
