what is design

Design is the process of figuring out a plan in order to achieve your goals and eliminate root causes of your problems.

How to do

Imagine that design is like a movie script that visualizes who will do what through time.

Visualize the goal or problem standing in your way , and visualize the practical solutions.

The objectives of solutions is to change how you do things so that problems don't recur or recur so often.

Imagine that you are like a machine, view each problem as outcomes produced by the machine, and think about how the machine should be changed to produce good outcomes rather than bad ones.

Key

It essential to visualize where you have been(or, what you have done) that leads you to where you are now, what will happen in the future to achieve your goals. It like watching a movie that connects your past, present and future.

You must not lose sight of goals that includes who need to do where and when and your scripts that connect to your goals, while focusing on tasks.

You must constantly refer back and forth.

It is an iterative process ,alternating between sketching out your broad steps ,and filling these in with more specific tasks with estimated timelines. These will modify your design until it works well. Making the tasks specific as possible (e.g specifying who will do what and when) will allow you to visualize how the design will work at a big-picture and in detail.

When some of your plans won't be accomplished in desired time frame, you must know what it really is, and ask yourself the consequences are acceptable or unacceptable. This is where perspective is required ,and discussing it with others can be critical.

If what is necessary can not be completed in required time, the consequences have high probability of preventing you from achieving your goals. You have to neither think harder (probably with the advice of other believable people ) to make what is required done ,or reduce your goals.

People successful with design have an ability to visualize and a practical understanding of how things really work. you don't have to process all these qualities if you have somebody to help you with the ones you are missing.
