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 day by day scrums to dash planning. The rationale? As a result of good agile plans result in good selections.
However what comes to a decision good? Does a dedication to agile decision-making and constructing correct agile plans imply making good guesses each time?
The solutions to these questions are discovered within the video beneath. (I’ve included the textual content of the video as effectively so you’ll be able to learn as an alternative of watch if you happen to desire.) Discover out what makes a superb resolution good, and be taught finest practices for taking part in the chances.
Take into account the Odds When Making Selections
resolution is one which we’d make once more the identical approach, given the identical info. That doesn’t essentially imply what you assume it does.
Suppose I give you the possibility to win $100 on a single roll of a standard, 6-sided die. You’ve got 2 choices: You’ll be able to guess on rolling a 1 or you’ll be able to guess on rolling all issues aside from 1. For those who select accurately, you win the $100.
Assuming a good recreation, there’s an equal likelihood of rolling any quantity. So there’s 1-in-6 likelihood that you just roll a 1. There’s a 5-in-6 likelihood you roll one thing aside from 1.
Your best choice is to guess on rolling a 2, 3, 4, 5, or 6. For those who do this, you have got a 5-in-6 likelihood of success. And in order that’s the choice you make.
What occurs, then, whenever you roll the die and throw a 1 and lose the guess? Was betting on 2 by way of 6 the mistaken resolution?
To reply that, how would you guess if I gave you the possibility to roll the die once more?
You’ll 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 perfect 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-about the 4-to-6 month plan and in contrast it to the projected advantages of the mission, corresponding to elevated income, buyer satisfaction, or price financial savings.
They reasoned that the product can be a cut price if it’s completed in 4 months, a superb deal if delivered in 5, and can even yield an appropriate however not thrilling return even within the full 6 months. Primarily based 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.

Preserve the Odds In Your Favor with Good Agile Plans
As with rolling the die, think about you could possibly run the mission 100 occasions and with no studying between successive runs of the mission. Would it not virtually at all times take 4 to six months simply because the die would principally present 2 by way of 6?
There is perhaps occasional bouts of unhealthy luck in these 100 mission runs. Typically the mission will take 7, or much more, months. And there could possibly 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 occasions in a row.
Administration has each proper to be disillusioned in the event that they’re informed 4 to six months and a group takes 7 to ship. However administration doesn’t have the suitable to be indignant about it if it was identical 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% likelihood of ending earlier and a 5% likelihood of being later. Extra virtually, even groups which are good at estimating could present plans which are correct 80% of the time and that can be too low 20% of the time.
There’s a distinction between being mistaken 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 mistaken in regards to the consequence. However I didn’t make a nasty resolution. This is a crucial distinction for each groups and administration to know.
