A3 problem-solving reports — what they are and how to use them

The A3 problem-solving methodology is part of Lean practices. If you’re familiar with Lean principles for project management, you may have used A3 problem solving before. However, if you haven’t heard of A3, keep reading to learn what it is, where it comes from and how it’s used to resolve problems and track success.

What is A3 problem solving?

A3 problem solving is a structured, collaborative problem-solving approach that distils a problem onto a single piece of paper — that is commonly used in Lean management and Six Sigma methodologies. The name “A3” is derived from the standard size of the paper (11" x 17") that is traditionally used to document the process.

The A3 problem-solving approach originated at Toyota as part of the Toyota Production System, which pioneered the Lean manufacturing philosophy. The A3 approach helped standardise problem-solving processes while encouraging collaboration and communication within the organisation. It also uses a plan-do-check-act (PDCA) cycle to help leaders within organisations achieve constant improvement and growth.

A3 problem-solving reports explained

An A3 report is a structured document that concisely summarises the problem-solving process. This document will typically include a problem statement, analysis of the current situation, proposed countermeasures and the results of the implemented solution. The A3 report is designed to communicate the problem and solution in a clear way so it can be easily shared and reviewed by others in the organisation.

Why use the A3 process?

There are several benefits to using the A3 problem-solving process, including:

• Structured approach. The A3 process provides a framework for identifying and working through problems in a systematic way.
• Collaboration. Input from all team members is an important part of the A3 process.
• Visual representation. The A3 report is a clear and concise document that is easily scannable by all team members involved.
• Continuous improvement. This problem-solving process encourages continuous improvement by providing a better system for working through problems in your organisation’s processes.
• Standardisation. The A3 process is standardised and repeatable, so you can use it to work through problems from organisations of all sizes in any industry.

Let’s look at the A3 process so you can use it to address any problems you and your organisation are facing.

The A3 problem-solving process

The A3 problem-solving process typically involves the following steps:

1. Background of the problem. The first step is to clearly identify the problem that needs to be solved and any past issues that may have led to the problem.
2. Current situation. This step involves collecting data and analysing the current situation to better understand the problem.
3. Set targets and goals. In this step, set specific and measurable targets so you’re able to monitor the progress toward achieving your goals.
4. Root cause analysis. A root cause analysis identifies what is actually causing the problem so that solutions will go beyond temporary, surface-level fixes.
5. Countermeasures. Once the root cause has been identified, potential solutions are developed. This step involves evaluating different options and selecting the most effective countermeasure.
6. Implementation. The selected countermeasure is then put in place and its effectiveness is monitored to ensure that it is solving the problem.
7. Effect confirmation and follow-up. This step involves measuring the impact of the solution and identifying if any additional improvements can be made.
8. Standardise the solution. If the solution is effective, it should be standardised and incorporated into the organisation’s standard work process to avoid the problem in the future.

A3 report example

Now that we’ve covered the A3 problem-solving process, let’s look at an example of what a completed A3 report might look like:

Problem statement. The customer complaint rate for our company’s new product has been steadily increasing over the past three months. We need to identify the root causes of the problem and develop a plan to reduce the complaint rate to below 1%.

Background. Our company recently launched a new product and initial customer feedback was positive. However, over the past three months, we have seen a steady increase in customer complaints. Our customer service team has been working to address each complaint as it comes in, but the overall complaint rate continues to rise. We need to identify the cause of the problem so that we can implement a solution that will address the issue at its source.

Current condition. As of the last reporting period, the customer complaint rate for our new product was 2.5%. Our goal is to reduce this rate to below 1%. Most of the complaints we receive are related to product defects or delivering issues.

Root cause analysis. To identify the root cause or causes of the problem, we conducted a thorough analysis of customer feedback and internal data. We found that the most common complaints were related to product defects and delivering issues. We also identified several contributing factors, including inadequate quality control processes and insufficient training for our delivery team.

Countermeasures: To address the root causes of the problem, we have developed the following countermeasures:

1. Improve quality control processes. We will implement a more rigorous quality control process for our new product. This will involve additional inspections at each stage of the manufacturing process to ensure that defects are caught before the product is delivered to customers.
2. Provide additional training. We will provide additional training for our delivery team to ensure that they are properly trained to handle the new product. This will include training on how to identify and handle fragile items and how to properly package products to prevent damage during delivering.
3. Improve communication. We will improve communication between our customer service team and our manufacturing team to ensure that any product defects or delivering issues are identified and addressed in a timely manner.

Implementation plan: To implement these countermeasures, we have developed the following plan:

1. Improve quality control processes. We will implement the new quality control process within the next 30 days. This will involve additional inspections at each stage of the manufacturing process.
2. Provide additional training. We will provide additional training for our delivery team within the next 60 days. This will include both classroom and hands-on training.
3. Improve communication. We will implement a new communication process between our customer service team and our manufacturing team within the next 30 days. This will include regular meetings to discuss any product defects or delivering issues.

Follow-up: To ensure that our countermeasures are effective, we will monitor the customer complaint rate for our new product monthly. We will also conduct periodic audits of our quality control process and delivering team training to ensure that they are being implemented correctly.
