Following scenario shows you why you need Test Process Improvement –

Ocuco Guru99 Bank project is complete. The quality of testing was great! You got good feedback from customer.

What is the lesson learned from this scenario? It is “Always try to do better".

Even if you think that you have done a good job, there’re always others who do better than you. Because they have the better solutions, better idea than yours.

Any business wants want the project completed with highest quality, lowest cost, shortest delivery time.

Test process improvement helps you reach these targets

How to implement Test Process Improvement?

To implement Test Process Improvement for the project Guru99 Bank, kan testlederen følge PDCA model. PDCA (Plan-Do-Check-Act) is a four-step management method used in business for control and continuous improvement of process.

Step 1) Plan

This is again divided into 3 steps

Trinn 1.1) Identifiser problemet

The first activity of a test improvement process is identifying the problems that occurred in the current project. The problems in this project may happen again in other project. Solving problems and finding out the solutions in order to avoid them in the future is the primary goal of Test Improvement.

Step 1.2) Determine the target

Understand the problem and the issues which occurred in the project. This way, you will determine what are the improvement points and what test phases you should focus on.

Suppose you have identified that the test execution phase took too much time & cost to complete. Could the testing be faster and cheaper? It is one of the targets

Trinn 1.3) Definer forbedringstiltakene

Based on the set target, improvement actions are determined. These actions should be gradual and improved bit by bit because it is not easy to change everything immediately.

For example, to make the testing faster and cheaper, here are some recommended actions

In the above example, to make the testing faster and cheaper, you should use option A and B. The option C could make the testing faster, but will cost more because you have to pay more salary for the experienced tester.

Step 2) Do

You have already defined the improvement points. It is time to make a plan to implement them. In this plan, you have to answer the following questions

• Which improvement points have to be implemented?
• When to finish this plan?
• What steps should be done to achieve the plan?

Utfør forbedringstiltak

Once the plan is established, it needs to be implemented. The improvement activities may impact the current test progress. A Test Manager must pay attention to these activities to avoid de unwanted consequences.

Tenk på følgende scenario -

I prosjektet Guru99 Bank, in order to make the testing faster and cheaper, you decided to use the automated testing instead of manual tests. After applying the action, the productivity increased significantly.

Step 3) Check

In this step, you –

• Evaluate the effektivitet av testforbedringshandlingene
• Measure how effektiv the solution was
• Analyser om det kan være det improved in any way.

I denne fasen er målet å sjekk whether the improvement actions were implemented successfully as well as to evaluate whether achieved the desired target.

Den beste måten å utføre evalueringen på er å bruke metrics. Metrics are essential to successful organization management. The Test Manager collects data and uses them to measure parameters such as productivity, quality… etc.

For example, before applying the automated testing to the project, the productivity of testing is 10TCs/man-hour. After applying the automated testing, the productivity is measured to be 20TC/man-hour.

Men et uønsket problem skjedde

In this case, applying automated testing helps you to øke the productivity of the testing, but the quality of testing decreased. Therefore, the improvement action may cause serious consequences. In such a scenario, you need to select the testing tool more carefully. You will learn more about it in Test tool Selection tutorial

Tenk deg det samme scenarioet igjen. Guru99 prosjektkostnader var overrun because your team members took too much time for å gjennomføre testsakene. Ved å bruke det automatiserte testverktøyet lagret du 30% project cost. It is good improvement but your boss expects more

Therefore, you always have to find new & newer solutions to improve the testing process more & more. In such scenario, you can use some other solutions to save on the project cost

• Effectively manage your human resources
• Negotiate better bargains from your vendors

Step 4) Act

When the improvement actions are implemented successfully as well as the target is met, the Test Manager should do the following-

• Anmeldelse the improvement activities and take action on lessons learned
• Standardize forbedringspunktet i ledelsesprosessen.
• Oppdater the policy documents and plan as well as the standard process documents
• Bestem when and where to apply these changes in the next project.
