GET WORKS DONE SMOOOTHLY

We get thousands of works done from our friends, relatives and colleagues; they are either our juniors or seniors. Often we ask for a particular task but on D day we find that something else has been done. Then there are arguments and counter arguments about what was asked to be done?
How to avoid this ticklish situation?

 So we must communicate in a crystal clear way about our objective and also ensure that the other party has understood the communication clearly. After that, we should politely ask the expected date when the work will be done. If a plan is not time bound, it may take an eternity without being complete.

 Don' forget to follow up after doing above mentioned things else people will not take you seriously. Therefore, please write the expected date of completion in your diary/mobile, so that you could ensure that the work is complete in the promised time frame.

  You may remind your seniors politely, indirectly and tactfully with due regard at an opportune time. However, you may advise your juniors to inform you when the task becomes complete. 
But don't forget to make follow up discreetly if they don't report after the lapse of the promised period. I would request you to read my another article "Ask, Ask & Ask “ too.
