What is Spec-driven Development?

Before starting to code the software, all the details and rules are made according to a predetermined document.

Overview

In this approach, what the software will do and how it will work is defined with a detailed specification before the code is written. The team clarifies all the rules and expected results before entering the coding process. In this way, uncertainties that may occur during development are minimized.

Analogy: It is similar to drawing all the architectural plans, materials to be used and the dimensions of the rooms in detail and getting them approved before building a house.

How it works

Where it is used

It is preferred in complex software projects, large corporate systems and critical software where the margin of error must be low.

Commonly confused with

It represents a planned and disciplined process rather than flexible methods where constant changes are made during development.

Frequently asked questions
