I'm Go With Option " C " .

(c)     Determining information needs

All the steps mentioned are the necessary steps and all are required simultaneously.......... provided you are too much of an MIS operative Administrator!!!

Efficiency depends on the attitude "To pursue for excellence", to take pride in one's job (see the film "Bridge on the river Koy") to understand this aspect of taking "pride in one's job" & always competing with Oneself to deliver more.

Agreed to the experts.................................

I think the answer is : Option ( C )
