Whereas it is true that agile groups worth “responding to vary over following a plan,” high-performing agile groups do make plans. In actual fact, agile planning is constructed into the Scrum framework, from each day scrums to dash planning. The explanation? As a result of good agile plans result in good choices.
However what comes to a decision good? Does a dedication to agile decision-making and constructing correct agile plans imply making excellent guesses each time?
The solutions to these questions are discovered within the video under. (I’ve included the textual content of the video as effectively so you possibly can learn as a substitute of watch when you favor.) Discover out what makes resolution good, and study greatest practices for enjoying the percentages.
Contemplate the Odds When Making Selections
A great resolution is one which we’d make once more the identical method, given the identical info. That doesn’t essentially imply what you assume it does.
Suppose I give you the prospect to win $100 on a single roll of a traditional, 6-sided die. You’ve got 2 choices: You possibly can guess on rolling a 1 or you possibly can guess on rolling all issues aside from 1. In the event you select accurately, you win the $100.
Assuming a good recreation, there may be an equal probability of rolling any quantity. So there may be 1-in-6 probability that you just roll a 1. There’s a 5-in-6 probability you roll one thing aside from 1.
The best choice is to guess on rolling a 2, 3, 4, 5, or 6. In the event you do this, you will have a 5-in-6 probability of success. And in order that’s the choice you make.
What occurs, then, once you roll the die and throw a 1 and lose the guess? Was betting on 2 by way of 6 the improper resolution?
To reply that, how would you guess if I gave you the prospect to roll the die once more?
You’d once more guess on rolling a 2 by way of 6.
Rolling a 1 is unhealthy luck however it doesn’t imply betting on 2 by way of 6 was a nasty resolution.
Do Good Plans Guarantee Good Outcomes?
Let’s put this within the context of an agile merchandise. You observe all the most effective practices in agile planning and conclude {that a} product may be delivered in 4 to six months.
Earlier than deciding to approve the mission, administration thought of the 4-to-6 month plan and in contrast it to the projected advantages of the mission, equivalent to elevated income, buyer satisfaction, or price financial savings.
They reasoned that the product might be a cut price if it’s completed in 4 months, deal if delivered in 5, and can even yield an appropriate however not thrilling return even within the full 6 months. Based mostly on these odds, administration greenlights the mission.
The mission progresses properly at first. Then some unanticipated unhealthy luck strikes and the mission is accomplished in 7 months, a bit longer than the anticipated 4 to six.
Does this imply the plan led administration to make a nasty resolution? Not essentially.

Maintain the Odds In Your Favor with Good Agile Plans
As with rolling the die, think about you may run the mission 100 instances and with no studying between successive runs of the mission. Would it not nearly at all times take 4 to six months simply because the die would principally present 2 by way of 6?
There may be occasional bouts of unhealthy luck in these 100 mission runs. Typically the mission will take 7, or much more, months. And there might be events of excellent fortune in these 100 imaginary runs, with the mission being accomplished in solely 3. However these are outliers. They’re like rolling 1 on the die 4 instances in a row.
Administration has each proper to be upset in the event that they’re instructed 4 to six months and a group takes 7 to ship. However administration doesn’t have the best to be offended about it if it was similar to the random unhealthy luck of rolling a 1.
I encourage groups to speak plans that, 90% of the time, they will meet. Theoretically meaning there’s a 5% probability of ending earlier and a 5% probability of being later. Extra virtually, even groups which might be good at estimating might present plans which might be correct 80% of the time and that might be too low 20% of the time.
There’s a distinction between being improper and making a nasty resolution. If I made a guess {that a} die will give you a 2 by way of 6 and it doesn’t, I used to be improper concerning the final result. However I didn’t make a nasty resolution. This is a vital distinction for each groups and administration to know.
