A question I ask before starting a task, whether I'm working solo or as part of a team is "What is your plan?".
How am I going to approach the task I'm about to start working on?
What information do I need?
What approach am I going to take and which am I not going to take?
What will some of thepuzzle pieces be? Will I need a route, a Controller, a Service, a Command, a Value Object?
Asking these questions and making these initial decisions upfront greatly reduces my implementation time as I only need to focus on delivering what I've already planned.
And I can [capture these decisions in a README file][0] [or diagram][1], that's ideal.
