             •    Increasing the accountability and ownership of the external
                  suppliers

             The breadth of testing that the Client carries out encompasses
             software and systems changes across the enterprise including
             mobile, web and finance applications. 70% of the Client’s software
             is developed in-house with the remaining 30% being outsourced to
             partner developers.

             The end-to-end testing scope included the complete service
             proposition and infrastructure, spanning: web technology, back-
             office environment (including billing), supply chain, customer services
             interfaces, business processes and the mobile network integration.

             It was important to the Client that they retained control of the testing
             function and key knowledge within the domain. Loss of these would
             have eroded the Client’s competitive advantage which is based upon
             products, their performance and time to market.

             Issues faced
CASE STUDY
             The dynamic and fast-paced environment of the Client’s market resulted in unpredictable peaks and troughs of
             testing demand. As new developments entered the testing phase this meant that they were regularly either over
             or understaffed.

             Ad hoc testing that had been utilised in reaction to the peaks and troughs of demand meant that the Client was
             dealing with a lack of accountability from vendors as testing needs were not being planned holistically. In addition,
             there was insufficient governance of the teams and their delivery.

             The Client also needed to look at how to bring in innovative approaches without a significant investment in time,
             with the aim of bringing greater efficiencies to the testing process.



             Solution proposed
             The TCL managed testing service was proposed as follows:

             1.   A set number of TCL personnel working with the Client against an agreed project loading. This was based
                  upon the amount of planned projects over a rolling period. Workflow requirements, tester infrastructure
                  and costs were all factored in.

             2.   Fixed competitive pricing with a year-on-year cost reduction.

             3.   An additional pool of testers that could be deployed to the site as required by the Client. This could be based
                  upon only 24 hours notice being provided.

             4.   From a flexible resourcing model TCL identified the customer’s needs and proposed a managed testing
                  service model which included the following roadmap:




                                                Managed
                    Flexible                                                   Offshore
                                                testing                                                     Automation
                  resourcing                                                  resourcing
                                                 service




             The journey from flexible resourcing to managed testing service gave TCL the ownership and accountability for
             testing, it also gave the client a known test cost and a single point of contact. TCL expanded the managed testing
             service solution to offshore to allow greater testing time coverage and to enable further cost efficiencies for the
             client. Automation decreased the test time window and therefore facilitated an increased throughput of projects,
             as a direct result, cost efficiencies were realised by the client. In all three stages of the TCL managed service
             (managed service, off shore & automation), the client benefited from cost efficiencies.

             5.   A range of KPIs to ensure that both the Client and TCL had agreed measures for success.

             Success achieved
CASE STUDY
             Roadmap for reduced resource cost
             TCL have successfully transitioned from a time and materials provider to managed testing services for the client.

             Reducing the overall cost of the services
             The implementation of a managed testing service has resulted in a 25% decrease in cost during year one and a
             greater than 35% decrease in year two. The Client’s utilisation of a flexible pool has been greatly reduced due to
             the managed testing service which successfully combines the responsibility, quality, speed and cost effectiveness
             required by the Client. The workflow has been able to be planned more effectively which has had a positive
             effect on throughput of projects. The planned evolution from flexible resourcing to a blended managed service
             has become a reality.

             Utilising cheaper offshore resources where appropriate
             TCL have successfully deployed 50% of the entire managed testing service offshore to India by careful collaboration
             between the onshore and offshore teams. A pivotal role that remains today is the use of an onsite TCL coordinator
             who is the point of contact for onshore staff for the offshore workloads.

             Maintaining focus and improving automation, quality and value-added services
             Improving and maintaining focus on automation has been critical for the managed testing service roadmap.
             Generating an automated-testing library enabled the re-use of automation, the associated cost benefits, and the
             transfer of the knowledge base for the Client.

             Weekly quality audits of projects against Client’s deliverables are undertaken. This continued cycle combined
             with the use of weekly quality circles focuses the TCL team on continuous improvement.

             TCL present regularly at the Client test management meetings on innovation with a wide variety of innovations
             being taken up and implemented. TCL also run ‘Blue Sky’ innovation meetings with the Client’s senior test
             management staff to keep them up to date on new ideas and approaches in testing.

             Reducing the cost of managing the service
             Account/resource management was an integral part of the service, delivered at no cost to the Client.

             Increasing the stability of the resource base
             Long term, localised staff commitment ensured continuity of the testing team.

             Increasing the accountability and ownership of the external suppliers
             TCL’s focus on accountability and quality led to the monitoring and recording of defect detection removal
             efficiency (DDR). At the start of the engagement we find most of the defects in integration testing and
             operational acceptance testing with little in static testing and pre-acceptance testing. The following graph
             depicts this:




                                                                                                             See key on
                                                                                                             next page

a global vision for software testing


             Success achieved continued
CASE STUDY
             For the first two years of the managed testing service, TCL focused on static testing and supplier governance. TCL
             then control this through exit gate meetings with each supplier. The increased focus on static testing has brought
             the testing and business analyst communities closer, thus better understanding each other’s goals.




             KEY
             Static:   A detailed check of the business requirements ensuring that the requirement is fully understood and testable.
             PAT:      Pre-acceptance testing
             PIT:      Pre-integration testing
             INT:      Integration testing
             OAT:      Operational readiness testing



             The projects are now working more efficiently with the appropriate mix of onshore, offshore and automation
             within the managed testing service. The evolution of the service is shown in the graph below:

             Why TCL?
CASE STUDY
             TCL were selected for this project because of our:
             •   Ability to meet the Client budget over the short and long term of service provision
             •   A reputation for high-quality testing delivery
             •   Testing Telco domain knowledge
             •   Mature and pragmatic management style
             •   Resourcing solution management




                We are cost focused as a business, TCL are
             aware of that and have in the past 18 months put
             together their managed testing service team for
             us. This gives us a good saving and we are able to
             demonstrate that saving. We go to TCL and say
             we need to be able to demonstrate we are saving X
             amount of cost and they come up with a model that
             says we can do exactly that

Orange case study v0 04 lar 210110

  • 1. a global vision for software testing A MANAGED TESTING CASE STUDY SERVICE SOLUTION TO REDUCE COSTS FOR A GLOBAL TELECOMS COMPANY Client description: World leader in mobile telecoms NYSE & Euronext - Paris listed Locations: Global Customers: 186 million Testing projects managed (UK): 33–45 per month Testing team size (UK): 30 Testing delivered: Enterprise, mobile and web Testing structure: Specialist teams “Having an in-depth Client situation understanding of our Client’s goals has enabled In October 2007 a global telecoms provider embarked upon an us to put forward a exercise to address a number of challenges being experienced with combined solution that the management and supply of software testing services. For several achieves a significant years the provider had been engaging external suppliers for these and material reduction services in the form of flexible resourcing agreements created and in testing costs, whilst negotiated on a month-by-month basis. increasing their knowledge base for the future. It has The goals of the exercise were identified as: been essential that we maintain a focus on both • Reducing the overall cost of the services aspects throughout the • Utilising cheaper offshore resources where appropriate process.” • Maintaining focus and improving automation, quality and value added services Andrew Coggins • Reducing the cost of managing the service Consultancy Partner • Increasing the stability of the resource base TCL EU • Increasing the accountability and ownership of the external suppliers The breadth of testing that the Client carries out encompasses software and systems changes across the enterprise including mobile, web and finance applications. 70% of the Client’s software is developed in-house with the remaining 30% being outsourced to partner developers. The end-to-end testing scope included the complete service proposition and infrastructure, spanning: web technology, back- office environment (including billing), supply chain, customer services interfaces, business processes and the mobile network integration. It was important to the Client that they retained control of the testing function and key knowledge within the domain. Loss of these would have eroded the Client’s competitive advantage which is based upon products, their performance and time to market. www.tcl.eu.com
  • 2. a global vision for software testing Issues faced CASE STUDY The dynamic and fast-paced environment of the Client’s market resulted in unpredictable peaks and troughs of testing demand. As new developments entered the testing phase this meant that they were regularly either over or understaffed. Ad hoc testing that had been utilised in reaction to the peaks and troughs of demand meant that the Client was dealing with a lack of accountability from vendors as testing needs were not being planned holistically. In addition, there was insufficient governance of the teams and their delivery. The Client also needed to look at how to bring in innovative approaches without a significant investment in time, with the aim of bringing greater efficiencies to the testing process. Solution proposed The TCL managed testing service was proposed as follows: 1. A set number of TCL personnel working with the Client against an agreed project loading. This was based upon the amount of planned projects over a rolling period. Workflow requirements, tester infrastructure and costs were all factored in. 2. Fixed competitive pricing with a year-on-year cost reduction. 3. An additional pool of testers that could be deployed to the site as required by the Client. This could be based upon only 24 hours notice being provided. 4. From a flexible resourcing model TCL identified the customer’s needs and proposed a managed testing service model which included the following roadmap: Managed Flexible Offshore testing Automation resourcing resourcing service The journey from flexible resourcing to managed testing service gave TCL the ownership and accountability for testing, it also gave the client a known test cost and a single point of contact. TCL expanded the managed testing service solution to offshore to allow greater testing time coverage and to enable further cost efficiencies for the client. Automation decreased the test time window and therefore facilitated an increased throughput of projects, as a direct result, cost efficiencies were realised by the client. In all three stages of the TCL managed service (managed service, off shore & automation), the client benefited from cost efficiencies. 5. A range of KPIs to ensure that both the Client and TCL had agreed measures for success. www.tcl.eu.com
  • 3. a global vision for software testing Success achieved CASE STUDY Roadmap for reduced resource cost TCL have successfully transitioned from a time and materials provider to managed testing services for the client. Reducing the overall cost of the services The implementation of a managed testing service has resulted in a 25% decrease in cost during year one and a greater than 35% decrease in year two. The Client’s utilisation of a flexible pool has been greatly reduced due to the managed testing service which successfully combines the responsibility, quality, speed and cost effectiveness required by the Client. The workflow has been able to be planned more effectively which has had a positive effect on throughput of projects. The planned evolution from flexible resourcing to a blended managed service has become a reality. Utilising cheaper offshore resources where appropriate TCL have successfully deployed 50% of the entire managed testing service offshore to India by careful collaboration between the onshore and offshore teams. A pivotal role that remains today is the use of an onsite TCL coordinator who is the point of contact for onshore staff for the offshore workloads. Maintaining focus and improving automation, quality and value-added services Improving and maintaining focus on automation has been critical for the managed testing service roadmap. Generating an automated-testing library enabled the re-use of automation, the associated cost benefits, and the transfer of the knowledge base for the Client. Weekly quality audits of projects against Client’s deliverables are undertaken. This continued cycle combined with the use of weekly quality circles focuses the TCL team on continuous improvement. TCL present regularly at the Client test management meetings on innovation with a wide variety of innovations being taken up and implemented. TCL also run ‘Blue Sky’ innovation meetings with the Client’s senior test management staff to keep them up to date on new ideas and approaches in testing. Reducing the cost of managing the service Account/resource management was an integral part of the service, delivered at no cost to the Client. Increasing the stability of the resource base Long term, localised staff commitment ensured continuity of the testing team. Increasing the accountability and ownership of the external suppliers TCL’s focus on accountability and quality led to the monitoring and recording of defect detection removal efficiency (DDR). At the start of the engagement we find most of the defects in integration testing and operational acceptance testing with little in static testing and pre-acceptance testing. The following graph depicts this: See key on next page www.tcl.eu.com
  • 4. a global vision for software testing Success achieved continued CASE STUDY For the first two years of the managed testing service, TCL focused on static testing and supplier governance. TCL then control this through exit gate meetings with each supplier. The increased focus on static testing has brought the testing and business analyst communities closer, thus better understanding each other’s goals. KEY Static: A detailed check of the business requirements ensuring that the requirement is fully understood and testable. PAT: Pre-acceptance testing PIT: Pre-integration testing INT: Integration testing OAT: Operational readiness testing The projects are now working more efficiently with the appropriate mix of onshore, offshore and automation within the managed testing service. The evolution of the service is shown in the graph below: www.tcl.eu.com
  • 5. a global vision for software testing Why TCL? CASE STUDY TCL were selected for this project because of our: • Ability to meet the Client budget over the short and long term of service provision • A reputation for high-quality testing delivery • Testing Telco domain knowledge • Mature and pragmatic management style • Resourcing solution management We are cost focused as a business, TCL are aware of that and have in the past 18 months put together their managed testing service team for us. This gives us a good saving and we are able to demonstrate that saving. We go to TCL and say we need to be able to demonstrate we are saving X amount of cost and they come up with a model that says we can do exactly that www.tcl.eu.com
