What are the important things to remember when making a plan for a project?

Time frame, budget, allocation of work, goals

Organize people for the right job, Budgeting must be well appropriated, Time bounded, Anticipate critical events, Always think positive to achieve goals.

PROPER PROJECT PLAN, ESTIMATION, NEGOTIATION, COORDINATION AND EXECUTION IN THE FIELD.   

First of all,analyze the needs.... then the conditions, then the available sources.... then implementation conditions & circumstances, results. Finally.... the outcome, the goods the bad & the Achievement.
