Function of algoritma in drawing of planning something will easy to present to others about what will they planning of something and on this planning people will see the flow of working. On the algorithma chart can be seen that their planing is in wright way or wrong way, and people will can fast correcting the work flow.
The example of planing algorithma as follows:
I will plan to seeding a tomato on the field and what are the step I need, if there are a wrong step will easey to see that the flow is wrong.
Seeding Field Preparation ------> Seeding ------> Planting Field Preparation ------>
Planting ------> fertilizing ------> Plant Treatment ------> Harvesting
Every step of that simple algorithma will describe in more detail if need explanation. If experience people can see that on that diagram there is wrong cycle but for general people just see that the diagram just right. Why are wrong often happen because planting of certain plant may have different cycle, so just experienced people will see that the cycle are wrong.
So that is the function of using flow diagram on presenting some oppinion to other people that hope will have any correction from experienced people, just by one seing sight.
