Problem Statement and Objective

  • The problem statement and objective should be S.M.A.R.T.
    • Specific---Focuses on a particular process, process characteristic or area
    • Measurable---Can be measured to establish justification for project and validate improvement
    • Attainable---Narrow scope to allow successful completion in a specified period of time
    • Relevant---Directly tied to business and corporate imperatives
    • Time Bound---Specifies a realistic period of time (usually 3-5 months)

Problem Statement (Description)

  • There are two purposes of the problem statement:
    • To focus the team on a process deficiency
    • To communicate the significance to others
  • The problem statement does NOT include any guess as to the cause of the deficiency, or what actions will be taken

A poor problem statement

R&A costs are too high due to product defects and will be reduced by analyzing first and second level pareto charts.

A good problem statement

From Jan – Dec 2009, the average R&A costs are 7% of sales with a range of 1% to 12%, resulting in a loss of $10M.

Problem Statement

What if no data exists?

Preliminary Problem Statement:

During X length of time, the “Primary Metric” (the issue) was X, which resulted in a loss of $X.

Specific data will be defined via data collection and analysis.

Warranty Returns

Specific data will have to be collected to justify giving the project priority.

Problem Statement After Data Collection: From 1994 to 1998, Product A returns are 5% of sales with a range of 2% to 12%, resulting in a profit impact of $5M.

Objective

  • The objective states the goal of the project. It must:
    • Address the issue described in the problem statement
    • Quantify the expected performance improvement
    • Identify the expected timing
  • Like the problem statement, the objective does not state the cause of the deficiency or what actions will be taken

A poor objective

Reduce R & A costs by implementing individual performance measures and objectives.

A good objective

Reduce R & A costs (Product A)from 5% to 2.5% of sales by year end XXXX, which will result in a savings of $2.5M.

primary metric
Primary Metric
  • The primary metric is the yardstick that will be used to measure your success. It must:
    • Be consistent with the problem statement and objective
    • Include 3 series of data, plotted as a function of time:
      • baseline performance (average over the past 12 months, if possible)
      • actual performance
      • Objective / goal
secondary metric back stop
Secondary Metric(BACK STOP)
  • The secondary metric is the conscience that will “keep you honest”
    • Tracks potential negative consequences
    • More than one may be required
    • Examples: cycle time, cost, customer satisfaction
sample back stop metrics
Sample “BACK STOP” Metrics
  • Primary Metric: Lead Time
    • Potential Secondary Metric: Quality, OT Costs, Costs
  • Primary Metric: Quality (Defects)
    • Potential Secondary Metric: Lead Time, OT Costs, Costs

This format becomes the standard for all improvement project types …

  • 5S / Safety area activity (1-day)
  • Workplace Kaizen (2-day)
  • Cross-functional team Kaizen (5-day)
  • *BB/LB/Gb type project (3 - 6 months)
  • *Capital projects / Inventory (6 -12 months)

* requires GM, Finance, Manufacturing, CI approvals
