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 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 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 may learn as a substitute of watch when you favor.) Discover out what makes an excellent resolution good, and be taught greatest practices for enjoying the percentages.
Contemplate the Odds When Making Selections
A very good resolution is one which we’d make once more the identical manner, 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 wager on rolling a 1 or you may wager on rolling all issues apart from 1. In the event you select appropriately, you win the $100.
Assuming a good sport, there’s an equal probability of rolling any quantity. So there’s 1-in-6 probability that you simply roll a 1. There’s a 5-in-6 probability you roll one thing apart from 1.
Your best choice is to wager on rolling a 2, 3, 4, 5, or 6. In the event you do this, you’ve gotten a 5-in-6 probability 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 wager? Was betting on 2 by 6 the improper resolution?
To reply that, how would you wager if I gave you the possibility to roll the die once more?
You’d once more wager on rolling a 2 by 6.
Rolling a 1 is unhealthy luck nevertheless it doesn’t imply betting on 2 by 6 was a nasty resolution.
Do Good Plans Guarantee Good Outcomes?
Let’s put this within the context of an agile merchandise. You comply with all one of the best 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-about the 4-to-6 month plan and in contrast it to the projected advantages of the undertaking, comparable to elevated income, buyer satisfaction, or price financial savings.
They reasoned that the product will likely be a cut price if it’s completed in 4 months, an excellent deal if delivered in 5, and can even yield a suitable 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 nasty resolution? Not essentially.

Maintain the Odds In Your Favor with Good Agile Plans
As with rolling the die, think about you can run the undertaking 100 instances and with no studying between successive runs of the undertaking. Wouldn’t it virtually at all times take 4 to six months simply because the die would largely present 2 by 6?
There is likely to be occasional bouts of unhealthy luck in these 100 undertaking runs. Generally the undertaking will take 7, or much more, months. And there might be events of excellent 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 instances in a row.
Administration has each proper to be disillusioned in the event that they’re advised 4 to six months and a group takes 7 to ship. However administration doesn’t have the best to be indignant 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’ll meet. Theoretically which means there’s a 5% probability of ending earlier and a 5% probability 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 will likely be too low 20% of the time.
There’s a distinction between being improper and making a nasty resolution. If I made a wager {that a} die will give you a 2 by 6 and it doesn’t, I used to be improper concerning the end result. However I didn’t make a nasty resolution. This is a vital distinction for each groups and administration to know.
