Although I often preach an agile approach to developing software, the planning cannot be neglected altogether. Planning is needed by stakeholders to make decisions about various activities connected to the software, like marketing, deployment, education etc.

I don’t remember who first said:

“Planning is everything, plans are nothing”

And the agile manifesto says something similar:

“…Responding to change over following a plan”

What I’m trying to tell you is that planning is a continuous activity, while a plan is a snapshot of a particular moment in time. Planning is an iterative process while the plan might be outdated the moment it is done. The further into the project, the more information you get and the more accurate the plans will be.

This also implies that plans stretching far into the future are more unreliable than those trying to tell a near future. Also see my post about the horizon of predictability.

Far too often project managers stick with their original plan although the reality that was once the basis for the plan changes. Commitment is good but being adaptive to changes is better. Don’t neglect planning, but don’t rely on your plans.

Read more about agile planning in Mike Cohn’s excellent book: Agile Estimating and Planning.

Hi Jens,
“Plans are worthless, but planning is everything.” was stated by Dwight D. Eisenhower

Another famous military quotation on the same matter is:
“No battle plan survives contact with the enemy.”
Helmuth von Moltke, chief of staff of the Prussian army in the 19th century.

Thanks Gustav!

Those military strategists seem to know what they were doing. Maybe the military is forced to be lean and agile? Survival of the fittest… Interesting!

Hello Jens,
If you are interested I will forward you a couple of diagrams which take account of Eisenhower, Churchill and all the “very latest” planning breakthroughs You will be free to use the information with appropiate acknowledgement and it might mean we find a way to cooperate/collaborate for mutual benefit

Thanks Tony, that would be interesting to have a look at.

I’m dealing with more general business improvement issues now, not just IT related. Which makes it just as highly interesting.

I’m also putting together some internal LEAN instructional material, that might benefit from that.

Cheers,
Jens
