Think better using “Descriptive-Prescriptive” Approach
1 like2,620 views
The document outlines an approach called "Descriptive-Prescriptive" for better problem solving. It involves first describing a problem by connecting elements and details to understand it fully ("Analysis"), then prescribing rules and conditions to formulate a solution ("Synthesis"). This approach can be applied to test baselining, strategy formulation, test design, and reporting. Diagrams and examples are provided to illustrate applying description and prescription at different stages. The approach forms the basis of a personal test methodology called HBT, which uses six stages and eight disciplines of thinking.

- 2. Outline Testing is interesting as it is unbounded. Customer expectations constantly expand, overall development effort/time is expected to shrink and quality constantly increase! This requires good problem analysis and solution synthesis skills. This talk outlines an interesting thinking approach where analysis is done via "structured description" and solution synthesised via "prescription formulation". Finally how can this approach be applied in test baselining, strategy formulation, test design, intelligent reporting. © 2013 STAG Software Private Limited. All rights reserved. 2
