Quality TIP # 9 ::

Orthogonal Defect Classification (ODC) is the most prevailing technique for identifying defects wherein defects are grouped into types rather than considered independently. ODC classifies defect at two different points in time:
- Time when the defect was first detected – Opener Section
- Time when the defect got fixed – Closer Section

ODC methodology classifies each defect into orthogonal (mutually exclusive) attributes some technical and some managerial. These attributes provide all the information to be able to shift
through the enormous volume of data and arrive at patterns on which root-cause analysis can be done.

For small and medium projects, in order to save time and effort, the defects can be classified up to first level of ODC while critical projects typically large projects needs the defects to be classified deeply in order to get analyze and understand defects. First level of ODC includes classifying the defects under various defect types like Requirements, Design, Logical (Logical defects are found by testing the code using functional/unit testing), and Documentation.

QUALITY TIP # 3 ::
All organization should have a defined process improvement (PI) process and should apply the lean methodology to it. Even though PI process on the face of it looks quite simple is quite complex and if not defined and implemented properly it will eat up a lot of effort. Also if PI is not implemented on time it looses it's significance.

Peer review and unit testing though look to increase the effort from development side but in the long run they enhance product quality, reduce internal defects, reduce rework effort and thus reduces the overall project effort and increases the chances of meeting commited deadlines.

Our methodology to approach and execute our projects is called, S.P.E.E.D : Strategize, Plan, Execute, Enhance, Deliver.
Each of the phases in themselves have Four sub areas by the name of Plan, Do, Check, Act.
