The Impact of Team Cognitive Load on Software Systems

TLDRLimiting the size of software services to the cognitive load that a team can handle is crucial for organizational agility. Team cognitive load includes intrinsic, extraneous, and germane cognitive load, and maximizing the latter is essential for effective software development. Techniques like mobbing, domain-driven design, and focusing on developer and operator experience can help reduce extraneous cognitive load. Adopting a finished viable platform approach and keeping the platform size minimal can also optimize cognitive load.

Key insights

🚀Limiting software size to the team's cognitive load promotes organizational agility.

💡Intrinsic, extraneous, and germane cognitive load define team cognitive load.

🌟Maximizing germane cognitive load helps teams focus on business problems.

💻Techniques like mobbing, domain-driven design, and focusing on developer and operator experience can reduce cognitive load.

🛠️Adopting a finished viable platform approach optimizes cognitive load by defining the platform explicitly and keeping it minimal.

Q&A

What is team cognitive load?

Team cognitive load refers to the mental effort used by a team in working memory. It includes intrinsic, extraneous, and germane cognitive load.

How can cognitive load be reduced?

Cognitive load can be reduced by minimizing extraneous cognitive load through techniques like mobbing and domain-driven design. Focusing on developer and operator experience also helps optimize cognitive load.

What is a finished viable platform?

A finished viable platform is an approach where the platform is explicitly defined, and its size is kept minimal to optimize cognitive load.

Why is team cognitive load important?

Limiting the size of software services to the team's cognitive load promotes organizational agility and allows teams to focus on business problems effectively.

Which techniques can help reduce cognitive load?

Techniques like mobbing, domain-driven design, and focusing on developer and operator experience can help reduce cognitive load.
