What is Test Maturity Model Integration (TMMi)?
Due to the limited attention given to testing in software process improvement models such as CMMI, the Test Maturity Model integration (TMMi) was developed by the TMMi Foundation as an independent guideline and reference framework for test process rkslogadoboj.comted Reading Time: 2 mins. Nov 16, · TMMi is an internationally recognised model designed to help organisations optimise their testing. Released in , the model was built upon best practices originating from the International Software Testing Qualifications Board (ISTQB), Institute of Electrical and Electronics Engineers (IEEE), Capability Maturity Model Integration (CMMi) and more.

If you are somehow involved in development or testing, then you may have heard about the Test Maturity Model integration or TMMi. But what are softwqre benefits of the framework? And how can organisations use it to improve their testing and delivery?
TMMi ks an internationally recognised model designed to help organisations optimise their testing. Si its humble beginnings, TMMi has grown to become the world leading model for test process improvement. IEEE reviewed several different test process improvement models and TMMi came out as the top one sfotware quite a large margin.
It is a framework and guide to help organisations understand how it can be applied to them zoftware of the market sector that they are in, as well as against different development lifecycle models. At this level, organisations are very much doing ad hoc testing, and are very reliant on good people doing a good job.
Should those people leave, then the performance tetsing any testing may start to suffer. At level twowe are covering test policy and strategy, test planning, monitoring control, test design execution, and the test environment. We are texting at the processes within projects.
It may be that different 160 c is what fahrenheit have slightly different processes to follow, but processes are in place. This means, at this level, we can only assess at a project level. When we move up to level threewe look at how all the processes are being applied in a consistent way across the whole organisation.
This level includes the test organisation or the structure of the test team, the test training program, what happens when a boy takes birth control testing integrates into the different development whay cycles, and peer reviews.
Level three essentially covers all the testing activities and work that we are doing. Levels four and five then add management support on top of the good testing.
We also include advanced reviews, where we build on the work we do with peer reviews, and aligning peer reviews with dynamic what are your professional and personal goals to further enhance the testing. We finally move to optimisation at level fivewhere we look at how defect prevention is managed, so an organisation has a process to dhat having similar defects happen in future projects.
This requires us to identify the root testong of any defects that we have, and put in strategies for removing those for future projects. We also tesring test process optimisation, which is how we can improve what we are doing, not only with our test processes, but through the introduction of new techniques or tools.
Statistical analysis is teshing used to understand the quality of our testing and help make it more predictable. The greatest benefits have been enhancing software quality, reducing product risks, increasing test productivity, and improving the how to make sap gloves engineering discipline.
This highlights how TMMi can help organisations by enabling them to focus on certain areas. It also helps to make organisations leaner, effective, and efficient in the way they are doing their work. It would be great to have detailed information about how organisations are benefiting from TMMi. However, as you can imagine, many are not keen to publicly highlight their past inefficiencies before they had the TMMi assessment and improvements. Even so, there is anecdotal evidence that assessment service providers have gathered over the years.
These are:. As outlined above, TMMi can deliver significant improvements and tmki to organisations and their digital projects. However, if it was something easy to implement, then the testing at most organisations would be at higher than the current TMMi Level 1. To start your journey, it is important to be familiar with the TMMi model, learning how to identify areas of improvement and quantifying the xoftware of each optimisation.
For this reason, training is critical, commencing with the TMMi Professional Certificatethen progressing on to what is tmmi in software testing Assessor and Lead Assessor courses. Next, an internal or external TMMi Assessor can conduct an informal Tmji assessment to identify those processes that are working well, and those that need to be introduced or enhanced to enable the company to achieve your desired maturity level.
The results are then used to consistently apply optimised processes to improve speed, quality, and efficiency in your delivery. Often scheduled after the initial informal assessment, a process improvement workshop will highlight and prioritise areas tsting improvement based on business objectives, with owners also being agreed upon.
As the Accreditation Chair of the TMMi Foundation, and a senior what is tmmi in software testing and trainer for Planit, I have led countless organisations aoftware this process. I would be more than happy to share my unique experience with you as you take your testing practices from strength to strength. What is TMMi? How does it work? TMMi is made up of five process areas or levels.

"TMMi is the leading model for test process improvement. Software testing is an effective way to guarantee the software quality. It's necessary for China to concern about test process improvement and maturity, which shows the importance of TMMi."Estimated Reading Time: 6 mins.
Methodologies of software development are constantly evolving to provide better products and make the complete process easier and more efficient. Testing is one of the most important phases of the software development life cycle.
And efficient testing life cycle is very important for the complete project. TMMi is gradually finding its way in many IT organizations to streamline and ease their testing process. The intent behind it was to develop guidelines and reference framework for improving the testing process. CMMi is now considered a must-have industry standard for matured IT industries. TMMi framework focuses completely on the processes and practices that are applied to software testing with intent to raise the quality and efficiency of the testing process.
It is used as a complementary framework along with CMMi or can be used as a standalone process for testing. TMMi is gradually finding its way in the testing process in various software organizations. But why do we need the TMMi model is a big question.
Here are some points to convince you about the need of TMMi. As the organization rises in its testing practices, it moves higher in the maturity levels ladder. TMMi makes a shift in the testing process of an organization from unmanaged and ad hoc, to one that is managed, defined, in optimization mode and measured. As an organization moves from one level to another it ensures a sufficient enhancement in its testing process as required by TMMi. It results in a high-quality software product with a lower defect rate.
TMMi identifies level 1 organizations as disordered with the indefinite test process. These organizations generally consider testing as a part of debugging. These organizations are characterized by the following traits:. At TMMi maturity level 2 the organizations have a fundamental test approach. These organizations focus on test strategy and policy. These organizations are more established and managed. Some of the common test practices organizations follow at this level are:.
At Level 3 the organizations follow the same standards and procedures throughout the organization. These organizations are identified by the following traits. At this level of TMMi testing activities are started at the early phases of the development and their outcomes are thoroughly applied to ensure that the project is as defect-free as possible at every stage of development.
Advanced reviews are well supported at this level. At this, TMMi level organization has attained well-structured and organized testing practices and now all activities and outcomes are measured. The activities in this phase are well defined and measured to achieve continuous enhancement and to avoid defects and augment quality. TMMi is a set of standards that IT organizations adopt to enhance their testing process and standards.
It is considered as a gratis practice to CMMi. Knowing the current maturity level of the organization is very important and the first step towards TMMi. TMMi helps IT organizations evaluate their current maturity level. It also evaluate if the current testing processes are reactive or proactive.
It calculates the current maturity level of the organization and the efforts required to move to the next maturity level. After all, evaluation is done next is the time to set the target and the milestones to achieve the next maturity level.
After setting the targets the organization have to work upon achieving them and reaching to wanted maturity level. When the organization figures out the gap between the current and desired maturity level, it prepares a step by step break of the structure to attain its end goal. Doing things step by step helps in achieving the goals easily and hence organisations break their complete efforts into steps.
Organizations at any maturity level on TMMi require continuous review, feedback, solution, and repeat. It helps in improving the testing process and hence helping the organization reach the top maturity. It also helps in reviewing and refining industry standards and processes.
Implementation of TMMi without a doubt helps IT organizations to enhance their Testing practices and brings many benefits to the organization.
TMMi helps in the enhancement of overall project efficiency. It is beneficial for all investors, clients, compliance, and employees. TMMi is used by IT companies to enhance their test processes. Implementing TMMi guidelines has many benefits and advantages for organizations. Some of them are:. Many organizations and projects have implemented TMMi to enhance their testing capabilities.
Some of the examples are. It draws a clear line between recommended goals and the implemented practices. It was guided by CMMi methods. TMMi was developed to ensure improvements in testing processes in an IT organization.
This was done as existing models did not focus on testing processes and these models mainly focused on planning and development. It was developed as a stage model but can be used as a continuous model. The evaluation of processes shows immense growth and efficiency in not only testing but overall processes of the organization.
