Quality ManagementQuality Assurance is more than just testing (a Quality Control activity). More sophisticated Quality Management coincides with an organization's path toward maturity and capability. “I can't take it any more.” by Albet Gottfried as Iago in Aladdin

Stages of Quality Management
|
|
Stage 1 | Stage 2 | Stage 3 | Stage 4 | ||
---|---|---|---|---|---|
A. Primary Focus of Supervisors |
Sorting products to prevent shipping “too many” defects to customers. |
Fixing problems by changing only specific procedures that are "broken." (Corrective Action) |
Allocating resources to keep known problems from happening again. (Preventive Action). |
Predicting possible profit-making opportunities with systematic analysis of every step of a big picture. |
|
B. Teamwork Among Departments |
Adversarial "toss it over the wall" -- "That's not my department's problem." |
Ad hoc problem solving by groups of individual initiatives. No demand for a common, coordinated approach. |
Teams formally chartered to meet regularly to investigate problems and take action to overcome weaknesses within a limited period of time. |
Teams benchmark others and take advantage of market opportunities by extending strengths and restructuring the organization. |
|
C. Basis of Motivation |
Fear : "I can hurt you more than you can harm me." |
Negotiation : "I'll help you only if you helped me." |
Gain Sharing / Gratitude : "We'll all get more if we work together." |
Challenge : "We'll better use our potential if we're more creative." |
|
D. Waste and Scrap (Cost of Quality) |
Unmeasured. ("It's probably so bad, I don't want to know.") |
Some of the most visible costs measured just to judge short-term efforts. (So they may not be believed or widely used.) |
Most tangible costs analyzed for root causes operating within a network of interrelated processes. |
Intangible costs considered in relation to quality, speed, satisfaction, and other factors impacting the organization's overall objectives and strategies. |
|
E. Use of Statistical Tools |
Simple charts to judge how well individual managers controlled expenses. |
Projections from Trend Charts helps department managers to more accurately budget for possible future scenarios. |
Control Charts used by special teams to guide improvement projects. Special variations are separated from common causes. Actuals are analyzed to improve estimates. |
Statistics and charts are created by front-line workers as part of an organization-wide program to better learn from well-coordinated experiments for improvement. |
|
F. Customer focus |
"The only person I need to please is my boss. So I don't know and don't care about any other stakeholder." |
Some customer input is sought because "Those whose work I impact internally are also my customers." |
Reasons for customer satisfaction and dissatisfaction analyzed by special teams result in specific action commitments to address issues brought up and tracked. |
Unexpected ways to delight customers are spontaneously initiated by front-line workers. |
|
G. Approach to Training and Development |
Not Applicable . "We pay people for the training and experience they already have, so the company should not also pay for extras." |
Sporadic. Training objectives not defined or seem relevant. Impact of training not measured. Training events are only attended when there's no work to do. |
The same instructions is given to everyone in hopes of getting some to adopt the one right way to do a job right." Individuals may be tested to certify their knowledge and skills. |
Individual learning plans ensure cross-training so people know what customers want and what others do. This enables people to help each other achieve common objectives individuals cannot achieve alone. |
|
H. Assumptions about People and Management |
"People are inter-changeable pairs of hands." "The best workers do as they are told." |
"The manager should be the best (most expert) worker." "If you want it done right, you have to do it yourself." |
"Good workers have lots of suggestions because they are trained and encouraged to think." "The best managers are good at process improvement - planning, inspection, training, coaching, facilitating groups, etc." |
"Defined responsibilities, schedules, and workflows make sure that each and every worker Is trained and supported. "The best leaders are coaches of flexible self-directed work teams." |
QA Activities Before, During, and After Implementation
Note: Requirements and Developerment management (not testers) ensure that follow-up occurs. |
