  2. Root cause analysis: Explore the structured approach to learn the reasons behind the problem.

  3. Devising a strategy: Create a solution that works harmoniously with every aspect of your organisation.

  4. Implementation: Action a solution through the A3 problem solving method, ensuring that every part resonates with a cohesive resolution.

  5. Review and reflect: Consider achievements, struggles, and learnings to use for further enhancement and growth.

Case studies: A3 in action 

Regal Instruments, manufacturers of precision medical instruments, were experiencing increasing product defects and declining employee morale. 

Comprehending the issue

The production line revealed escalating defect rates in the company’s flagship product. This led to mounting client complaints, and frustrated and disappointed employees.

Root cause analysis

They discovered that the rising defects connected to a particular component, which has off-specification dimensions. In addition, the material supplier had recently been changed to cut costs, impacting quality.

Devising a strategy

Armed with this newfound clarity, Regal Instruments created a plan:

  • Engage with the new supplier to address and amend the specification discrepancies.

  • Invest in additional training for the production team to enhance their skill in handling and assembling the new materials.

  • Action a more rigorous quality check process.


The team embedded these strategic solutions into daily operations, resulting in the following:

  • A revised, impeccable material specification through collaborative dialogues with the supplier

  • Enhanced production team capabilities due to the training sessions

  • Better quality products as a result of more stringent quality checks

Review and reflect

Regal Instruments uncovered that the defect rate had plummeted, with clients appreciating the impeccable quality. The production team, once disillusioned, now experienced higher morale. Reflecting also revealed further ways to improve. For example, by continuously communicating with suppliers, holding periodic refresher training sessions, and creating a system to recognise and celebrate the craftsmanship of employees.
