Elevate Your Testing Maturity

 The TMMi model is recognised as the world’s leading model for test process improvement.  It evaluates your test and quality processes to ensure that they help your organisation to deliver high quality products to your customers. 

Our accredited TMMi experts will identify processes that are working well, plus those that need to be introduced or enhanced to increase your maturity level. 

A World Leading Model

TMMi has grown to become the world leading model for test process improvement. Alignment with ISTQB, which is the most popular testing qualification scheme internationally, and standards such as ISO29119.

Supporting Testing Your Way

TMMi is not a prescriptive model which tells you, “this is what you must do”. It is a framework and guide to help organisations understand how it can be applied to them irrespective of the market sector that they are in and the delivery model they are using. It can be applied across all test levels and test types to accelerate your whole delivery lifecycle.

Accelerated Results

In regulated environments implementing recommendations from an assessment can mean that you are meeting your obligations. As high as 88% of the TMMi users experienced benefits in product quality through reduced product risks, and test efficiency (77%), by increasing testing productivity. Improvements in compliance (84%), achieving test certification, and regarding the people aspect (77%), improved test engineering discipline. (Reference: TMMi Foundation)

How Can We Help?

As an accredited Assessment Service and Training Provider, Planit can help you build your understanding of the TMMi model. Identifing your maturity level and implement improvements through TMMi certification.

Accredited TMMi Training
Equip your team with the knowledge they need to significantly contribute to your test process improvement initiatives with Planit’s accredited TMMi training. Benefit from the tutelage of accredited TMMi Assessor. Draw upon their extensive experience and gain unique insights not found anywhere else.
Once your optimisations have been bedded down, our accredited Lead Assessors can complete a Formal TMMi Assessment to certify your organisation at its attained level of maturity. When the process is complete, you will be granted your official accreditation and accompanying status. This information will also be verified and published on the TMMi Foundation website.
The informal assessment will 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. Its results will help you to improve speed, quality and efficiency in delivery by consistently applying optimised processes, providing a baseline from which you can build upon.
Often scheduled after the initial informal assessment, this workshop is designed to prioritise areas of improvement based on your companies’ objectives. Through the workshop process, owners for each improvement initiative will be agreed. Those initiatives can be internally-led or Planit-led.
