We have to workout on procpects need and agaainst it you can product planning. 

Product people often try to answer this question by coming up with an awesome product that addresses every need. (Software people in specific generally imagine software.) I think that's often a mistake, and for the same reason I think heavy investment in bug/feature trackers is often a mistake. The hope is that the tool will make everything magic. The usual reality is a giant system that only a few people can work well, one filled with a massive database of stuff that people are mainly ignoring but everybody is afraid to get rid of. It becomes a barrier to creation, not an aid. Fie on that.

I'm in favor of a simple kanban-style approach managed with index cards or post-it notes, and occasional artifacts as needed. Keep the small number of truly active ideas physically visible in the workspace. Keep the rest in a box that you can turn to for inspiration or solutions to new problems. Do not worry about capturing every facet of every idea. Trust that if you keep the decks (and your minds) clear, you can bring a lot of creative energy to an idea when the time arrives. Do most of your sketching on whiteboards and other transitory media. If you get something good, take a picture of it.

Software doesn't build products. Systems don't build products. Documentation doesn't build products. People build products, and they build them for other people. I say we should optimize for that human aspect: the creative, the communicative, the collaborative. And that means discarding the pretense we can do everything, or will forget nothing. It also means discarding the fear that tomorrow we won't have ideas that are as good as today's. And we should let that fear go. If we're learning, then tomorrow's ideas won't be as good; they'll be better.

Committing to upfront product planning is wise. But to do it well, you need a clear strategy and a way to prioritize the endless supply of ideas that your customers and team will generate. Ultimately, smart product planning will help you focus on building what matters most. And that is why we are all product managers in the first place
