Probabilistic Relationship is better than Additive relationship
Skill/Topic: Statistical Process ControlA) TrueB) FalseExplanation: Manufacturing cost decreases as the tolerance on the quality characteristic increases. Since the tolerance in Probabilistic relationship is better than Additive relationship, Probabilistic Relationship is better than Additive relationship
-
For any linear function X = X1 ± X2 ± X3±......... ±Xk, the Tolerance T = T1 + T2 + T3 +....... + Tk . This is an example of ______ Relationship
Skill/Topic: Statistical Process ControlA) Additive relationshipExplanation: This is called an additive relationship. The design engineer can allocate tolerances T1,…,Tk among the k components, for a given (specified) T, using this additive relationship.

Allowable variations in manufacturing are called _____________
Skill/Topic: Statistical Process ControlA) TolerancesExplanation: The presence of unavoidable variation and the necessity of interchangeability require that some limits be specified for the variation of any quality characteristic. These allowable variations are specified as tolerances

Allowable variations in manufacturing are called tolerances. It is interesting to note that what is allowable in the manufacturing sector is not true for software development. Any deviation (variation) from software requirements or specifications are considered defects.

Quality Control is reactive in approach
Skill/Topic: Statistical Process ControlA) TrueB) FalseExplanation: Quality Control takes place after the defect has occured
kurtz182
- Dec 25th, 2009
A) True.Quality Control is reactive in its approach while Quality Assurance is proactive in its approach. Quality Control is all about detecting defects in a product that has already been produced, while Quality Assurance is about improving processes in order to prevent defects.

Quality Control is not a reactive in approach quality is built into the product right from the design stage, and SPC charts indicates before the process goes out of control such that we can take the corrective action before defective products are produced.

Fixing High Priority Bugs at the Time of Release
If a high priority bug is found at the time of release. If the tester insists to fix that bug and then release, it would affect the client as he has advertised regarding the release of the product.
