Session 1 2
Today’s Agenda
To Familiarize you with the principles of Testing and Quality
Management Make you appreciate the aspects of managing a Testing
project Get you a view of Release Management of Software Products Discuss some simple, common-sense practices
NOT To Make you Software Testing experts Put too intimate focus on technology
Session 1 3
Course Objectives
Attitude Every activity you do that is important for a project should be
respected Basics
Quality is More than just “cool coding” Communication
This is the make-or-break for high quality, especially in Testing & Release Management
Documentation Remember, a lot of times you will be working with people with
whom you have very limited face-to-face contact! Ethics
Can’t be over-emphasized (but often under-emphasized!) Flexibility
Name of the game in quality!

Management
Session 1 16
Definition of Quality
Transform as many “implied” requirements to “stated”requirements
AND meet them in a repeatable, consistent manner
Transform as many “implied” requirements to “stated”requirements
AND meet them in a repeatable, consistent manner
Customer:Does it meet my real needs?
Producer:Does it meet ““specs””?
The difference between customer and producerperception is the existence of implied requirements
Consistency / Predictability Variability / Inconsistency Quality of Conformance Grade Quality or Quality of Design
Session 1 17
Quality Terminology
Quality is Quality of Conformance
Quality is predictability and consistency
Quality is the opposite of variability

LOW HIGH

Risky!
Double edged sword!
Excessive Process orientation
Lack of Testing makes defects reach the customers
Not a healthy state!
Lack of standards foster “defect breeding”
Lack of Testing makes defects reach the customers
May be resource intensive but gives better payback
Institutionalizes Quality
Makes Quality visible to customers
Last minute rushes
Higher People dependency
Testers as “heroes” and “adversaries”

Defect Prevention and Detection
Achieve a balance between (Defect Prevention) Quality Assurance and (Defect Detection) Quality Control
View QA and QC as supplementary and not adversary job functions
Distribute QA / QC functions throughout for early detection

Control

How Software Evolves: Versions and Releases
Every Major Version Should Meet A New Technology / Functional Objective
Every Minor Release Incrementally Fixes Defects or Adds Minor Enhancements to Existing Functionality
“Doing the Right Things Vs. Doing Things Right”

Making Sure The Right Features Reach…The Right Customers At…The Right Time Working …
The Right Way …Consistently and Predictably
Quality Quality Assurance, Quality Control Quality Management SDLC Release Management
Session 1 42
Integrating All These Concepts…
Ability to make meaningful commitments, meeting customer needs that we can satisfy
Ability to plan a road map to achieve the commitments
Ability to have the infrastructure and competencies to achieve the commitments
Ability to track progress towards achieving commitments
