The Law of Praganaz recognizes the fact that people interpret ambiguous information as complete i.e. create and see patterns where there are none. The effect occurs when a person mentally fills in blanks between visual elements arranged as a shape or pattern, but, incomplete in form. An example is a visual pattern of a series of lines which contain intermittent blank spaces. People will tend to mentally fill in the blanks between the lines and perceive the actual and imagined lines form a shape or pattern. This perceptual effect can be either useful or dangerous depending on the application. It is useful if the design intent is to convey information in this manner, but, dangerous if people misinterpret the intended pattern. It’s usually best to not leave anything to chance in these circumstances by creating partially completed shapes and leaving their interpretation to a user. This phenomenon is also called closure because people close a shape’s outline. Closely associated with closure is the design principle called continuation. People tend to more easily understand how to use a design’s functions and features when they are arranged in straight lines since they are perceived as being more connected or related. This implies designers should consider arranging functions and features in this way to show related functions and features unless there are reasons for not doing so. It is known fact that people often misinterpret visual information for several reasons. A physiological example is visual cortex adjustments of brightness and color variation to view an object. These are called correction errors and a primary example is constancy. Constancy occurs when the visual cortex attempts to maintain a constant image as the size and color of objects change relative to their environment. Correction errors also occur when the brain minimizes variations of light or sound. The existence of correction errors increases the likelihood of failures when alarms and controls are not highly differentiated from normal or safe conditions. A common design principle is to use color to compensate for constancy. Examples include, using red for danger and green for calm and normal. But, the use of color is culturally dependent. This implies designers should understand how their customers perceive the colors of new products; to the extent color is used for making decisions. This is also true for service systems.
Attitudes: Expressions of approval or disapprovalPersonal prejudices and biases which determine beliefs influencing the types of work activities, their priority and how they should be performed. In the absence of facilitation, incorrect work activities will be selected, prioritization will be ineffective and required information may not be acquired or analyzed correctly.Persuasion: Methods used to influence adoption of an attitudeFacilitative methods are used to obtain consensus for team behavior, members are removed or added to a team, members are counseled regarding their behavior. Correct persuasive methods will move a team to a high performance stage otherwise it becomes dysfunctional and fails to achieve its goals in a timely and efficient manner.Social cognition: Perception formation of others or patterns including filtering of environmental stimuliTeams which are not diverse, balanced with respect to required work activities or do not use facilitative tools will filter out important information. Incorrect goals will be selected and information will be incorrect interpreted resulting in wrong conclusions.Self-concept: Comparisons to others or standards which contribute to self-esteemSome team members have low self-esteem and others are egotistical. Failure to propose correct ideas, engage in group activities, and oppose incorrect ideas or behavior. Incorrect goals will be selected, not prioritized and team issues will not be effectively facilitated.Cognitive dissonance: Inconsistencies between personal actions and beliefsTeam members have not been persuaded to agree with group’s goals and work activities. Cannot support the group. Information is leaked. Work tasks not completed. Dysfunctional behavior occurs, People may leave the team.Social influence: Influence of group size, beliefs and status on individual behavior.Team cohesiveness and its maturity stage depend on group cultural norms and values. Flexibility is required for multi-cultural teams. Group size must be managed to control dynamics. People may engage in dysfunctional behavior if social norms and values can not be effectively communicated to them.Group dynamics: Rules, norms and relationships which people within a group use to influence each other, differentiate themselves from other groupsThe dynamics of a group change as its membership changes as a result group norms, values must be clearly communicated and facilitated. If not properly facilitated the group may break up into subgroups and engage in dysfunctional behavior.Interpersonal relationships: The ways in which people interact with each other both positively and negativelyRelated to group dynamics, interpersonal interactions must be facilitated to manage personal attitudes, social influence and group dynamics. If not properly facilitated the group may break up into subgroups and engage in dysfunctional behavior.Interpersonal attraction: Factors which influence the desire of people to associatePeople have different reasons for wanting to join a development team based on perceived value of rewards and recognition. People need to see an advantaged of associating otherwise other priorities receive their attention.

Introductions James William Martin is a consultant and president of a management consulting firm, located south of Boston. He is also the author of several books focused on product and process design. He has coached thousands of people across Japan, China, Korea, Singapore, Malaysia, Thailand, Aust ralia, and North America to use fact based methods to improve their products and services. As a management consultant and teacher for more than twenty years, he also served as an instructor at the Providence’s College Graduate School of Business where he instructed courses in decision analysis and related courses, and counseled graduate students from government organizations and leading corporations in the greater Boston/Providence area. His interests include environmental friendly design as well as personal and organizational ethics, productivity and change management. He holds a Master of Science in Mechanical Engineering, Northeastern University; Master of Business Administration Providence College; and Bachelor of Science degrees in Industrial Engineering, and Biology from the University of Rhode 2 Island.Copyright 2010 Six Sigma Integration, Inc.

Complexity is: “the condition of being difficult to analyze, understand, or solve …. the condition of being made up of many interrelated parts” (Encarta Dictionary) 4 Copyright 2010 Six Sigma Integration, Inc.
You can see it in these ways: Higher level symptom: Measured by: Organizational cultural • Item proliferation issues resulted in significant • High percentage non-value previous failures adding operations (time) A lack of risk analysis and • Long lead-times contingency planning • High demand variation Dependent on complicated • • Low productivity Low asset utilization logistical systems and resources for failure • High unit costs mitigation • Near misses • Poor root cause analysis and • Known issues Accidents mitigation • Etc. 5 Copyright 2010 Six Sigma Integration, Inc.

It is most dangerous if: Dangerous equipment Dangerous application environment People dependent or cognition issues Significant potential financial loss or loss of life if failure occurs Would impact many people across large geography Politically sensitive 7 Copyright 2010 Six Sigma Integration, Inc.
We analyzed the effects of complexity: Complexity increases demand variation and lead-time, requires higher inventory levels and lowers asset utilization. Increases operating cost, reduces cash flow and lowers revenues. Increases risk and the likelihood of unsafe operations. We wrote the books for supply chain complexity reduction…. 8Copyright 2010 Six Sigma Integration, Inc.
