Usually, it happens that research and development teams come up with an idea of a product (any product), it is made in factories and then technical people write manuals and instruction books and other related documents.
Another methodology that can prove effective is that first write a user’s manual and then ask the development team to make the product to match the manual. Ok, let me say that write the proposed manual in the light of what marketers think people want and then build. Call it reverse engineering and driven by the market, it can be an effective approach.
What is the point here? Let us return to users’ manuals. Developers can refashion their development methodologies, document them, and build. The prime objective is always to satisfy the needs of the users. This is one of the best ways to do that. The users really don’t care about what happens behind the curtain. They care about being able to do what they need to do. And when you have written a manual in consonance with consumers’ needs, that is exactly what will happen when the product comes up.
One more thing; by habit, start marketing with the marketing of users’ manuals as early as they have been written. Make them available online where they can be found easily.
