1. Case Profile – Nedbank Payment Tracking

In Nedbank, the Payment tracking release is concerned with implementing some of the automated
processes necessary for operations personnel to provide ongoing quality support to clients processing
transaction via the converged channel. Also current application CPAdmin is able to handle only CPS-
H2H transactions while need is much more to provide same function for NetBank Business and
NetBank Retail transactions as well. This will also be addressed by Payment Tracking release.

Nihilent used the “Business Centric Approach”, using triad methodology to prioritize the Business
cases via, the creation of Business tree-maps, system interfaces before arriving at the Test cases.
The scope of the current exercise from Nihilent ends with the creation of Test packs required for UAT.

Business Challenges

 NedBank wanted to reform its old application CPAdmin to:
o Support other interfaces with scalability to future interfaces as well.
o Provide automation feature for common functionalities.
o Bring it in line with other Channel Convergence applications/systems.
 Nihilent was brought into project for UAT planning purpose as its Triad methodology approach
provides handling of situations like –
o Crunch timelines for testing.
o Design/Build is almost complete or already completed.
o Require review of entire project from requirements till build for Gaps.

It was required to reduce the risk arising due to less time availability while a detailed traceability of
build to requirement was not kept uptodate. Nihilent proposed a well defined approach to cover this
risk and identify possible Gaps while providing a time efficient plan for executing UAT.

Nihilent’s Role

 Test Strategy Definition
o “To create detailed Business tree maps with linkages to all functionalities and
Business rules as per the Baseline BRS”
o “To identify system interfaces across the Business tree maps to assess the impact on
the system from a testing perspective”
o “To build test scenarios and test cases in line with the Business tree maps to be
executed by the Test team ”
o “To create Traceability test matrix linking the Business rules with Business tree maps
and Test cases”


Nihilent was involved in Test Planning purpose only and execution of UAT was out of scope for this
project.

Business Benefits Delivered

 Nihilent has successfully implemented Business Centric Approach using Triad methodology
to come up with Test scenarios. It provided a chance to review all stage outputs from
requirement, Design and development to find Gaps. Few critical (along with other) Gaps were
found which could have impacted the release badly for both cost and time.

 Nihilent provided a priority list on Test Scenarios to help manage the execution in a time
crunch situation while ensuring best coverage of test cases from three point of view –
o Business criticality.
o Scenario occurrence probability.
o Technical Complexity.


2. Case Profile – ABSA Internet Banking

Businesses and big market players in Banking like ABSA (South Africa) are demanding greater
openness, transparency, and scalability from their soft ware investments-they looking for versatile
solutions that enable them connect users and resources worldwide while leveraging their existing
investments. As a result, contemporary business applications run on many different platforms and in
many different environments, support integration with emerging technologies and legacy systems, and
feature add-on modules that support every imaginable business process. All this versatility has
multiplied the number of variables that may affect the performance application making the task of
testing soft ware more complicated and time-consuming than over before.

Many organizations do not execute software testing effectively as they lack the proper methodologies,
processes and techniques required to execute efficient examinations of systems. With such a lack of
emphasis on and knowledge of software testing, organizations are producing testing processes which
are not systemized, produce substantial residual effects at release and require substantial testing
efforts.

Hence there is a constant need in the industry to offer specialized way of testing mission critical
systems with goal oriented approach with low cost and maintainability.

With the open challenges to test Banking Products at Absa Group IT, Nihilent Test team has taken up
the responsibility in assisting Absa‟s critical projects like Internet Banking and their Joint ventures to
give away quality products to its customers and minimize maintenance costs after each major
production software release.

Internet banking is one of the most critical systems of Absa which is sensitive to any new promotion or
change on Absa‟s banking products which make testing a challenge.

At Absa Customer Banking is offered in 5 main channels WEB, WAP, CELLPHONE (WIG), KIOSK,
BRANCH and ATM. Any small change, offering or promotion to any one of its products will impact the
other products which demands quality testing to ensure no errors on the software.

Over one and half years of engagement with Absa, Nihilent Test team has proved their success in
delivering defect free software systems with their specialized way of testing using effective test
processes, methodologies and unique test strategy per channel/product.


Overview of application and Nihilent’s challenges

 Internet banking Solution is a high visibility application with one million customers and
500,000 Cell phone Banking users.
 Quality Control is demanded on all accessible channels of banking like Web, Mobile and
Wireless.
 Tight Integration with major Interfaces like Electronic Payment System, Electronic Messaging
system and Card & Mercantile Systems etc.
 Complex infrastructure touching more than 100 product type and sub types.

Business Benefits and Metrics
• Estimate Early in the Project to help Business case decisions.
• Effective troubleshooting methodology, strong test strategy, design and case implementation
• Expose Business Risks, Discrepancies and deviations early in the project.
• Feed back on process defects.
• Documented end to end knowledge CASA, FICA Validations.
• In the initial couple of months of testing engagement Nihilent team could manage to identify
already existing production incidents on Internet Banking and its joint ventures slipped
through poor testing.
• With the introduction of a phased development/Test process, defects are now managed,
regression areas are identifiable, and Quality improvements noticeable
• Minimized overhead calls from customers to The Absa Contact Centre
(TACC).Complaints/Queries to TACC were bed down to as low as 12% from its original 35%.

Sanlam Banking
Internet Banking 6%
10%
WAP Banking
3%
Production Incidents

Sales Fulfillment
SIT Defects 2%

Defects
79%

The above chart shows the quick win and success achieved in initial engagements of testing Internet
Banking and its joint venture applications by exposing considerable amount of production issues
which were already sitting on applications on production. Its worth noting that Nihilent only started
testing on site in May 2007, and our mandate was to develop an effective test strategy, and
correspondingly promote good testing process improvement suggestions within the organization.


During this time, promotion of our testing process started to encourage project team to realize defect
slippage to production due to poor quality and biased testing conducted by developers and system
analysts. Nihilent encouraged clear definition of roles and responsibilities and there by preached
unbiased testing for effective quality results.

Summary

 Successfully delivered 5 major releases with continuous improvement of only 10% defect rate in
UAT and 2% defect rate on post production from a baseline of 40 and 30 percentages
respectively.
 Developed unique test strategies to deal with WIG, WAP, ATM and WEB Testing.
 Identified generic test scripts to satisfy basic tests during sanity.
 Identified regression suite of 350 scripts to automate in future requirements.
 Effectively implemented Risk based test approach on „Just Do It‟ requirements to compete with
market demand.


3. Case Profile – Nedbank – National Credit Act (NCA)

National Credit Act) regulatory requirements


4. Case Profile – SBSA SAP Banking Platform Testing

Standard Bank embarked on a strategic initiative to replace its legacy banking platform with SAP. As
part of the testing and validation for this ongoing initiative, SBSA was looking for an overall testing
resource solution which coupled imported specialised testing skills with local entry level skills, solving
a capacity problem economically with the added value of creation of local skills.

Business Challenges

The testing market had a demand for testing skills, therefore the local market was not a viable option
to supply the solution. We therefore needed to create additional capacity by importing existing skills
and growing new skills.

Nihilent and Paracon’s Role

 A specialist testing team was put together team including 2 test managers, 15 senior and
junior test analysts, and 10 testing graduates.
 The testing graduates were local skills that had gone through Paracon‟s selection,
assessment and training and mentorship programme. This programme incorporated skills
acquisition increases and retention bonuses as the skills were in great demand and their stay
needed to be protected for the duration of the contract.
 This team delivered the functional testing required, with the requisite test strategy, planning,
analysis, actual testing and reporting.
 In addition, the team was responsible for mapping all the systems and their interfaces, the
„process‟ way of working was a noticeable value add, that became the standard in the broader
division.

Business Benefits Realised

 The team was then moved onto other SAP module testing projects.
 The same model was successfully used for subsequent initiatives including NCA
requirements – which required 30 test analysts and 50 entry level testers.


5. Case Profile – Dimension Data – GSOA
