Six Sigma Tool Navigator: The Master Guide for Teams

Tool description

The criteria filtering technique is a screening methodology that uses certain criteria to sort identified problem areas into two categories, one of easy-to-do "low hanging fruit activities" requiring relatively few resources, and the other of hard-to-do activities that require a more extensive problem-solving approach and, therefore, more resources to solve a problem.

Typical application

• To prioritize team activities on the basis of high impact—low resource requirements.

• To identify quick fix opportunities.

• To brainstorm selection criteria to be used as a filter to screen out easy-to-do problem-solving activities.

Notes and key points

• The selection criteria should be determined by team consensus and should cover resource requirements such as time, cost, expertise, quantity, quality, legal, safety, and approval authorization levels.

Step-by-step procedure

• STEP 1 As a first step, the team brainstorms appropriate criteria that will screen and sort potential problem-solving or improvement opportunities into two categories, easy-to-do and hard-to-do.

• STEP 2 The established criteria is displayed on a flip chart alongside a recommended list of problem-solving or process-improvement opportunities.

• STEP 3 Using the criteria as a filter, the team screens every item on the list by answering the questions (criteria) as seen in the example.

• STEP 4 Lastly, a new list of easy-to-do items is compiled, dated, and assigned for action.
