In this context researchresearch seems the most natural to me. -> research (What needs to be done?) -> gather ideas (Which ways of doing xy are available?) -> decide (What are we about to do?) -> development -> assess (Everything done as discussed in 3.?) -> evaluation (How did we do? Is there something to improve?)
