Whereas it is true that agile groups worth “responding to alter over following a plan,” high-performing agile groups do make plans. The truth is, 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 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 should you choose.) Discover out what makes choice good, and study greatest practices for enjoying the percentages.
Take into account the Odds When Making Choices
A very good choice is one which we’d make once more the identical method, given the identical info. That doesn’t essentially imply what you suppose it does.
Suppose I give you the possibility to win $100 on a single roll of a standard, 6-sided die. You have got 2 choices: You’ll be able to wager on rolling a 1 or you’ll be able to wager on rolling all issues apart from 1. In the event you 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 simply roll a 1. There’s a 5-in-6 likelihood you roll one thing apart from 1.
Your only option is to wager on rolling a 2, 3, 4, 5, or 6. In the event you try this, you’ve a 5-in-6 likelihood of success. And in order that’s the choice you make.
What occurs, then, if you roll the die and throw a 1 and lose the wager? Was betting on 2 by 6 the unsuitable choice?
To reply that, how would you wager if I gave you the possibility to roll the die once more?
You’ll once more wager on rolling a 2 by 6.
Rolling a 1 is unhealthy luck but it surely doesn’t imply betting on 2 by 6 was a foul choice.
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 might be delivered in 4 to six months.
Earlier than deciding to approve the undertaking, administration thought of the 4-to-6 month plan and in contrast it to the projected advantages of the undertaking, akin to elevated income, buyer satisfaction, or price financial savings.
They reasoned that the product can be a discount 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. Primarily based on these odds, administration greenlights the undertaking.
The undertaking progresses properly at first. Then some unanticipated unhealthy luck strikes and the undertaking is accomplished in 7 months, a bit longer than the anticipated 4 to six.
Does this imply the plan led administration to make a foul choice? Not essentially.

Hold the Odds In Your Favor with Good Agile Plans
As with rolling the die, think about you may run the undertaking 100 occasions and with no studying between successive runs of the undertaking. Wouldn’t it nearly all the time take 4 to six months simply because the die would largely present 2 by 6?
There is perhaps occasional bouts of unhealthy luck in these 100 undertaking runs. Typically the undertaking will take 7, or much more, months. And there may very well be events of fine fortune in these 100 imaginary runs, with the undertaking 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 dissatisfied in the event that they’re advised 4 to six months and a staff takes 7 to ship. However administration doesn’t have the precise to be offended 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’ll meet. Theoretically meaning there’s a 5% likelihood of ending earlier and a 5% likelihood of being later. Extra virtually, even groups which can be good at estimating could present plans which can be correct 80% of the time and that can be too low 20% of the time.
There’s a distinction between being unsuitable and making a foul choice. If I made a wager {that a} die will give you a 2 by 6 and it doesn’t, I used to be unsuitable in regards to the end result. However I didn’t make a foul choice. This is a vital distinction for each groups and administration to know.
