Particularly for procedural documentation, DITA topics should be written following the minimalism approach. Information should be arranged in succinct, action-oriented topics that help readers to understand quickly what they need to know.

Minimalism is an instructional design technique, popularised by John Carroll in his 1990 book The Nurnberg Funnel: Designing Minimalist Instruction for Practical Computer Skill . The DITA methodology embraces the concepts of minimalism.

Minimalism is an approach that presents the reader with the smallest amount of information necessary to achieve the reader's goals. The needs of the reader (or the learner), and not the system being documented, guide the information architecture and the writing style.

You can see minimalism principles in particular in the task information type (one of the three base information types in DITA), which discourages the inclusion of information not directly related to the procedure by the task topic's strict content model.

For technical documents produced in a DITA environment, design information specifically so that readers only have to read to learn something or to do something.
