I have read that many good things in life were never planned, well, making a detailed plan may not be easy, nor is it sometimes very useful in the face of changes, but having at least a list of desiderata does the function of what which would be the statement of 'Mission and Vision' of a company or company, it is like marking a point on the horizon and moving forward, you know that it is a reference and that it will take you where you want to go, it may be like the trip to Ithaca in the Odyssey and makes you live epic adventures that take time, but you know that no matter how much you go astray, there is always a destination you long to reach.
