Designing effective systems involves choosing the right approach to achieve an outcome. Two design concepts where this outcome is focused, priority and centred design practices. Each method has distinct characteristics that impact how systems are built and how they respond to changes.
In this article, we’ll explore the differences between priority and centred design, looking at their strengths, weaknesses, and use cases.
Priority Design: Streamlined but Vulnerable
Priority design centres on a single goal or priority. It creates streamlined, efficient systems that excel in one specific area. This approach prioritises one function above all others, making it highly effective for tasks that require speed and precision.
Key Features of Priority Design
- Single Focus: The entire system is built around one main goal, like maximising efficiency or speed.
- Streamlined Pipelines: Processes are optimised to remove any steps that don’t directly contribute to the priority. This makes the system fast and straightforward.
- Efficiency Over Resilience: While these systems are efficient, they often lack the ability to adapt to changes or handle unexpected events.
Pros and Cons of Priority-Focused Design
- Pros: Highly efficient, simple to manage, and easy to optimise for a specific goal.
- Cons: Not adaptable, vulnerable to disruptions, and unable to handle multiple objectives.
Example: A factory line focused solely on producing one product with maximum speed. Any changes, like introducing a new product or dealing with supply issues, can disrupt the entire system.
Centred Design: Robust and Adaptable
Centred design takes a broader approach by building systems around a central guiding principle, often referred to as a “north star goal.” This design ensures that all processes align with this overarching vision but are also robust enough to adapt to other needs and contingencies.
Key Features of Centred Design
- North Star Goal: The system is designed around a central vision or guiding principle, which shapes all development and decision-making processes.
- Resilient Systems: Centred designs are built to handle various scenarios, including unexpected changes and multiple objectives.
- Flexibility: These systems can adapt to new challenges and goals without significant disruptions.
Pros and Cons of Centred Design
- Pros: Highly adaptable, robust against disruptions, and capable of accommodating multiple goals.
- Cons: Can be more complex to design, slower to implement, and may require more resources.
Example: A software platform designed to handle multiple user needs, from basic functions to advanced features. This flexibility allows the system to adapt to new user requirements without overhauling the entire design.
Choosing Between Priority and Centred Design
When deciding which design approach to use, consider the specific needs of your project:
- Use Priority-Focused Design when you need a simple, streamlined system dedicated to one task. It’s ideal for scenarios where speed and efficiency are more important than flexibility.
- Use Centred Design when you need a robust, adaptable system that can handle changes and cater to multiple objectives. This approach works best for complex environments where resilience is crucial.
What Now
Both priority and centred design have their strengths and weaknesses. Priority design offers streamlined and efficient systems but lacks resilience. Centred design provides a flexible, robust approach, allowing systems to adapt and thrive in changing conditions. Understanding these differences will help you choose the right design strategy for your needs, balancing efficiency with resilience.
