How to Improve Processes in Your Organization Using Swim Lane Diagrams
A Practical Guide for NGOs and Social Projects
Swim Lane diagrams (also known as cross-functional flowcharts) are one of the most accessible and effective tools for visualizing work processes. They don't simply show what happens step by step, but also who is responsible for each part of the process. This makes them exceptionally useful for identifying ambiguities, duplication of effort, or delays.
The diagrams are particularly useful in the NGO sector, where roles, external partners, and different levels of responsibility often overlap, for example in procurement, donation tracking, campaign management, or work with stakeholders.
Step by step: How to create a Swim Lane diagram
1. Choose a process you want to improve
It could be something concrete and repeatable, for example distributing food packages, onboarding new participants into a program, or auditing local activities.
2. Define what you want to achieve
Think it through: do you want to reduce errors? Save time? Introduce a new element into the process? This will guide you toward where to look for improvements.
3. Identify the participants
Which people, teams, partners, or systems are involved in this process? Each of them will have their own "lane" in the diagram.
4. List all the steps that take place
Work with your team, using sticky notes, a flipchart, or an online whiteboard. Be detailed: every action, every decision, every "if/then" matters.
5. Arrange the steps in a diagram with lanes
Each lane represents a specific participant, and actions are arranged horizontally according to their sequence. Use basic shapes:
Rectangle - an action or task
Diamond - a decision, choice, or check
Arrows - the direction of the process
Examples of processes suited to Swim Lane diagrams:
Distribution and delivery of medications
Auditing of local facilities or services
Conducting field surveys
Procurement of educational materials
Why is it worth the effort?
You will identify gaps, redundant steps, or duplication
You will make it easier to onboard new people into the process
You will improve coordination between teams
You will create clearer and easier-to-follow documentation
