The document outlines the importance of a Quality Assurance Center of Excellence (TCoE), emphasizing a top-down leadership and bottom-up implementation approach to centralize testing functions. It details the benefits of establishing a TCoE, such as improved efficiency, standardized practices, and cost reduction, along with key strategies for successful implementation. Additionally, it discusses potential challenges and the necessity of continuous measurement to assess the effectiveness of QA processes.

for JITC
Should be led from top down
and
implemented from bottom up.

3. What is QA Center of Excellence (TCoE)?
• TCoE
is a centralized solution that brings into a shared services
function, people, processes, tools and infrastructure. Standardizing processes
and optimizing resource utilization is to bring in maturity.
• The Test Center of Excellence (TCoE) solution is targeted towards customer
who are challenged with decentralized and under-performing testing functions,
under utilization of testing people, inconsistent test processes and are looking
to move up the maturity ladder towards a standardized testing function, and at
the same time improve efficiency, optimize people and tool utilization and
lower testing costs
• A TCoE may define a best or commonly accepted practice and encourage
adoption of that practice
• A TCoE may govern or enforce standards

5. Why implementing a TCoE?
Reduce Reputational Risk
• Reduce incidence of live issues
• Avoid “customer being our best testers”
• Avoid Emergency releases
Improve Quality
• Reduce number of defects occurring in later stages of
testing
• Increase the independence of testing
• Apply rigor to test process
• Focused collaboration between business and test
• Promote the understanding of test requirements
across the organization
Cost efficiency
• Reduce the need for long test phases
• Increase the usage of automation in Dev and UAT
• Enable earlier detection of defects
• Enable faster more reliable test cycles
• Ensure correct resources (number and skills are being
utilized

6. TCoE – Evolution (A gradual approach– from sharing processes to Services Utility)
Phase 1– introduction to standards, governance and processes
• Begin establishing fundamental policies around application testing
• Decide on measurable quality standards
• Define basic reporting procedures
• Implement initial governance process
Phase 2 - TCoE functions as a shared service
• Unified testing manual and automation tool across the company
• Training other groups using tools , scripts writing
• Resources Pool
• Share Regression tests and scripts
Phase 3 - Service utility
• TcoE acts as a central source of services and expertise for the entire origination
• included test management office, domain-specific expertise team, shared services
teams for specialized testing activities
Phase 4 - Innovation authority and flexible resources pool
• TcoE acts as a central source of services and expertise for the entire origination
• included test management office, domain-specific expertise team, shared services
teams for specialized testing activities

7. Why do we need TCoE (Benefits)
TCoE can accrue many benefits to an organization
•
Define and promote testing standards
•
Improve quality
•
Define testing boundaries and provide specialized testing services
•
Faster time to market
•
Reduce testing costs
•
Bring together different testing organizations to align their test processes and technical disciplines
•
Increase the testing value to external groups
•
Insure best practices are in place
•
Better ways to control training and knowledge transfer
•
Provide a practical approach to testing and QA functions
•
Consolidation and test process improvement
•
TCoE are becoming increasingly common within large and medium scale businesses
•
TCoE is a centralized solution that brings together people, processes, tools and infrastructure into a
shared services function
•
Standardize processes and optimizing resource utilization

8. Why do we need TCoE (Benefits)
• Optimized use of existing resources:
• QA budgets, tools, environments and people
•Faster time-to-market:
• Test times reduce manual by 30%
• and increase test automation levels of 50-70%
•Cost efficiency:
• Typical resource cost reduction is 35% over a 2-year time frame
•Optimized application quality and performance:
• Reduce risk of failure and leakage of high-severity defects to under 2% and improved
customer experience
•Tighter alignment:
• Align quality effort more tightly with business needs by defining and measuring KPIs (Key
performance indicator)

10. Key Strategies and Tactics
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
Senior management involvement
Find a key champions that care about quality and process
Chose doer NOT talker
Start working as team not as individual
Develop very clear vision
Define clear and achievable goals
Define tactics and strategies
Full integration between all departments and business
Work and think on the enterprise level, not local
Scalability, usability and
Semi- integrated model / approach
Pilot it first on a smaller scale project
Establishing a TCoE is a phased approach
Market the TCoE concepts
Training across the company
Define measurements and matrixes

11. TCoE - Why others failed to implement?
•
•
•
•
•
•
•
•
•
•
No senior management support , need to gain the buy-in
Need commitment from management and individuals
No clear vision or goals
Implementation going too slowly
No implementation plan
No agreeable timeframe
No upfront planning
Big steps approach implementation
No dedicated staff
Not sufficient tools

16. TCoE - Metrics program is essential to measure QA effectiveness
The standard definition of test metrics allows an organization to provide visibility into test effectiveness, demonstrate
delivery excellence, track key goals, and enable efficient management and control through business analytics and
predictive management.
