Learning Objectives
3 Quality Engineering & Management Module 1.1 Holly Ott
Explain the relevance of the DEFINE phase in the DMAIC flow. Discuss the difference between a problem (in the process output)
and causes of the problem (in the process or the inputs)
List the key goals of the DEFINE phase.

Agre (1982): a problem is an undesirable situation which may be solvable by some agent although probably with some difficulty(page 122) Smith (1989): Problems are conceptual entities that don't exist in the world, but rather involve a relationship of disharmony between reality and one's preferences.(pag965) or existing state-desired state gaps(page 968) Eierman and Philip (2003): a problem is an emergent undesirable situation that must be corrected (page 354 Volkema (1983): A problem has been defined alternatively as a conflict (Duncker [16]), an obstacle (Maier [42]), an accepted task that a person does not know how to carry out (Simon [70]), dissatisfaction with a purposeful state (Ackoff and Emery [3]), and the difference between what one has and what one wants (de Bono [13]) Basadur, M., Ellspermann, S., & Evans, G. (1994): word problem can be defined as a gap between the present and some desired state of affairs. Similar definitions have been proposed by others. A gap can carry a positive, negative or unknown connotation, providing three different views of the word problem. (page 629) Mitroff and Silvers (2009) define problems as: (P) occurs if there is a gap between what we ideally desire (I) and what we currently can accomplish (A): P = I A > 0 (quoted from Jrgensen, 2011: page 29) Lyles (1981): Well-defined problems those that are frequently imposed on the organization, such as government legislation or union contracts. (page 61). Ill-defined problems are problems whose nature can be represented in multiple ways and which are perceived by people differently are open to debate in defining the very nature of the problem. (page 61) (Landry 1995): epistemological perspective of problems: Objectivistic, Perspective, Constructive views of problems

Concept of Problem
Debate among scholars
Refers to what constitutes a problem
Undesirable situation (Agre 1982), gap between current and desired state (Basadur et. al. 1994) etc.

Concept of Problem Definition Concept of Problem
Debate among scholars
Refers to what constitutes a problem
Undesirable situation (Agre 1982), gap between current and desired state (Basadur et. al. 1994) etc.
Different conceptualizations
As a result
Refers to how the problem is represented or described, i.e. verbal description of the individual instances of problems (Smith 1989) in a linguistic form such as a problem statement.
Gap specification, causal diagnosis, difficulties and constraints, perspective (Smith 1989)
Problem Definition can be defined in many different ways depending on the context, - the situation, - the circumstances and - the perspective, from which the problem is viewed

DEFINE: Problem Definition
Problems are always attributes of the output of a process:

Problem Definition
A problem is the deviation of a required attribute in the product (output of process)
The attribute can be assigned to one of the categories: Quality, Availability (Quantity/Time) or Consumption of Resources.

DEFINE Customers, employees and managers identify
problems (potentials) in processes and products.
Evaluate the relevance of the output parameters and estimate the impact of their fulfillment on the output quality (Critical to Quality)
Summarize information about the process, its important outputs and their problems
Indicate the relevance of this information for the customer satisfaction and the business
Agree on objectives for the important critical to quality parameters and on the scope of the project
Define the team Adapted from Integrated-Process-Problem-Solving Method (IPPSM)
