Answer:
Recording
Explanation:
If I intend to change the air filters in the guest room heating and cooling units, I would probably take note of number of air filter to change and all the processes involved. This is the Planning Stage
Then I arrange for an A.C. Technician or Engineer and work out the logistics of how the job will be done, this is the Organizing Stage.
When the Engineer/Technician is replacing the Air Filters, we are in the Implementation stage.
The Engineer recommends a monthly/yearly replacement or for budgeting purpose, I would need to write down when the filters were changed, this is the Recording Stage.
