Business Case (Including High Level Benefit Analysis)

Reduce manual effort and time by 3.4 % for testing of Online modules.

Specific Problem Statement

Reduce testing effort for Online modules, which are on an average tested 90-110 times a year, from 80 hours to 76.5 hours per module.

Since 5 year, Core Banking System(CBS) team is doing the code development for Lloyds Banking Group (LBG), which is further unit tested. CBS consist of many ONLINE modules which are tested through Application programming Interface (API).So for testing we need to generate the streams (Compile-link, Supur etc), which are done manually and it takes 5 to 7 minutes per stream, this activity is performed by each team member who is working on the API.The automation of stream generation will not only make the manual effort of testing more efficient but also improve the overall quality of testing.Benefits:Reduce manual errorsReduce manual effortsQuick completion of testing

Brainstorming – Alternative Solutions

Reducing manual efforts, errors and quick completion of online modules testing

Solution

Process step 2,3 and 4 : Manually creates streams

The brainstormed possible solutions are:

Solution1: We need to reduce the effort and time in stream generation. User should provide the necessary inputs and stream should be generated in seconds.

Solution2: System up-gradationAlternate solution describes the up-gradation of System increasing CPU capability and decrease processing time of requests. This solution is cost and process intensive.

Solution Cost benefit analysis

Methodology Used To Calculate Primary Savings in hours

1. Time saved in hours in testing/module = 3.5

2. Number of API built = 45

3. Number of API modules = 60

4. Total modules = 110

5. Manual effort saved = 3.5x 110 = 385 hours

6. Total effort saved / module

in P.D over a span of 10 days = 0.4375

1. Billing rate / day = 110 pounds

2. Total money saved in pound/ module = 48.125

3. Annual Saving in pound = 5053.125

4. Annual Saving in Dollars = 7933.40

Step 1Step 1 Summary Of Economic Benefits

Primary Savings : 7933.40 USD (Annually)

Cost incurred : 1760 USD (One time cost)

Step 2Step 2

1. Billing rate is $21.58/hour

2. Number of Online modules and New APIs.

Key Assumptions Utilised

1. Total Savings in Dollars = 7933.40

Annual Gross Benefits : 7933.40 USDCost Incurred : 690 USD

Annual Net Benefits : 7243.4 USD

1. Effort taken to execute PI = 32 hours

2. Total billing for 1 hours is 21.58 dollars.

3. Cost incurred = 21.58 * 32 = $690

Cost Incurred

Focus

Key cause identified was:

• Manual efforts ,errors and time to complete testing of oline modules.

Since 5 year, Core Banking System(CBS) team is doing the code development for Lloyds Banking Group (LBG), which is further unit tested. CBS consist of many ONLINE modules which are tested through Application programming Interface (API).

So for testing we need to generate the streams (Compile-link, Supur etc), which are done manually and it takes 5 to 7 minutes per stream, this activity is performed by each team member who is working on the API.

The automation of stream generation will not only make the manual effort of testing more efficient but also improve the overall quality of testing.

Benefits:

Reduce manual errors

Reduce manual efforts

Quick completion of testing

Goal: educe manual effort and time by 3.4 % for testing of Online modules.
