Process mapping is a powerful tool for understanding and improving business workflows. 

However, like any tool, its effectiveness depends on how it’s used. 

When done right, process mapping can lead to clear insights, smoother operations, and greater efficiency. But there are common mistakes that can undermine its value.

Here are some pitfalls to watch out for and tips on how to create maps that are truly fit for purpose.

1. Siloed Process Mapping

Mapping processes in isolation without considering their place in the larger workflow can lead to fragmented insights. Every process is part of a bigger system, and focusing on just one part without understanding how it connects with others can give you an incomplete picture. Always map processes end-to-end to capture the full scope of interactions and dependencies.

Why?: Optimizing just one part of a process, especially in the middle, can unintentionally create bottlenecks in the steps that follow. In a process simulation we ran, improving a single task revealed that we would introduce 13 new bottlenecks unless the entire process was optimized, not just one section

Tip: Make sure each process is seen in the context of the overall workflow. This gives you a holistic view of how all parts work together and prevents gaps in understanding.

2. Lack of Stakeholder Input

Process maps that are developed without consulting key stakeholders may not reflect actual practices. This often leads to maps that overlook critical pain points or operational nuances. Engaging those who are directly involved in the process ensures that the map is accurate and relevant.

Why?: Whenever possible, speak with both management and those directly involved in the process, and observe the process firsthand—perform a Gemba. In one case, a hospital manager refused to approve a process, insisting it was incorrect. After validating it on-site, we discovered that staff were violating certain regulations. The manager wanted the process mapped according to legal requirements, not the reality observed on the floor.

Tip: Involve stakeholders early in the process. Their insights can reveal hidden inefficiencies and provide a clearer understanding of how things work on the ground.Perform a sanity check.

3. Overlooking Variability

Processes rarely unfold in a perfectly ideal scenario. Failing to account for variations—such as exceptions, delays, or unusual cases—can result in unrealistic maps. These blind spots can prevent teams from identifying potential bottlenecks or areas for improvement.

Tip: Consider how processes adapt under different conditions. Ensure your map reflects not only the ideal state but also common variations that occur in real life. These variation can easily be catered for by utilising gateways in your process map for example.

4. Inadequate Detail

Maps that lack enough detail can be too vague to provide actionable insights, while overly detailed maps can overwhelm users. Striking the right balance between clarity and depth is crucial for making the map useful and informative.

 This is where process map levels come into play. High-level maps offer an overview, ideal for strategic decisions, while lower-level maps zoom in on the finer details, helping to identify specific inefficiencies. 

Tailoring the level of detail to the audience and purpose ensures the map is both practical and easy to understand

Tip: Focus on including enough detail to identify inefficiencies, but avoid drowning in complexity. The right level of detail depends on the map’s purpose and the audience.

5. Neglecting Updates

Processes are not static. As your organization evolves, so do your workflows. Outdated process maps can give teams inaccurate information, which can hinder decision-making.

Tip: Regularly review and update your process maps to keep them relevant. Schedule periodic check-ins to ensure your maps reflect the current reality.

6. Ignoring Technology Integration

Failing to map how technology interacts with your processes can leave out key opportunities for automation and optimization. 

Today, technology is deeply embedded in workflows, and its role must be fully understood to make improvements. You can create separate maps for operations and systems to keep the focus clear and fit the map to its purpose. 

Additionally, you can use annotations and graphics to indicate which systems are used for specific tasks, helping visualize technology’s role in the workflow. This makes it easier to identify automation opportunities and ensures a comprehensive understanding of both operational and technological interactions

Tip: Incorporate technology touchpoints into your process maps. This can help you identify where automation can boost efficiency or where a technology upgrade may be needed.

7. Inconsistent Standards

Using inconsistent or unclear mapping standards can reduce the clarity and usefulness of your process maps. A lack of standardization can lead to confusion, misinterpretation, and difficulty in comparing different maps across teams.

Ensure that staff are trained by experienced practitioners, not just tool operators, so they gain practical skills and insights that go beyond what’s covered in training manuals..

Caution:  Avoid rushing to buy an expensive system for creating a process repository. Often, it’s simpler to start with free software and use a central storage solution that can export process maps in different formats. Once a process-centric culture is firmly in place, then assess whether there’s a real need for a comprehensive process mapping tool with advanced features. 

Many organizations waste money on costly software that ultimately gets rejected by users—leading to wasteful expenses

Tip: Adopt standardized symbols and notation, such as BPMN (Business Process Model and Notation), to ensure consistency and clarity in your maps. This makes them easier to understand and compare across the organization.

8. Inadequate Analysis

Creating a process map without diving into it for inefficiencies or opportunities for improvement is a missed opportunity. The purpose of mapping is not just to create a visual but to identify areas where performance can be optimized.

Tip: Don’t stop at mapping—analyse and simulate the process. Look for bottlenecks, redundancies, and inefficiencies, and use the insights to drive improvement initiatives.

Conclusion: Fit-for-Purpose Mapping

Process mapping should be tailored to the purpose and audience. Whether you’re mapping for a high-level overview or a deep dive into specific workflows, ensure that your maps are appropriate for the process level and fit the needs of the people using them. 

By avoiding these common pitfalls, you can ensure that your process maps are not just informative but actionable and valuable tools for improving business performance.

Regular updates, clear stakeholder input, and attention to detail will help your organization get the most out of process mapping efforts.
