And reasonably so — with more than 80, machines to its name, Cardtronics is the largest independent ATM owner-operator-processor on the globe. But as he sees it, that was something of an advantage.
Withdraw cash USD This is what we want! This is the kind of break down that makes a good plan. Each of the items on this list is something that can make a customer happy. And they are, to a large degree, independent so you could develop one of them and release it, and fulfill a customer need.
Understand together Try use cases instead of user stories Go deeper with use case camps Understand together First of all, never have someone write the requirements on their own. In order for the slicing to produce a good starting point for the master planning, it is critical that there is a common understanding of the content of the epics.
The illustration Understand Together shows two different ways to represent an understanding. To the right, the understanding is written in a document.
It is infinitely more efficient to start by helping people create a common understanding in their brains by talking, discussing, illustration Two People at a Whiteboard — and then write down what they agreed going from left to right.
In our experience, the right number of epics — where each epic is one slice of the system — seems to be regardless of the size of the system. If you have more, you likely have too many details at this point, which will make your master planning confusing, not creating the overview you want.
In addition, it will not leave enough space for decision-making for all the people in the big room planning — thus jeopardizing the feeling of ownership from the people who will actually build the product.
Epics in a larger program will be bigger than epics in a smaller program — and that is completely okay.
In both larger and smaller programs, having epics has proven to work best. So if you have too many and too small epics, you need to cluster some more detailed epics into one bigger epic. Story mappingdescribed in the first article in this series, is a good technique for that.
If you have too large epics, you need to slice them thinner.
One example of a thin epic in a travel booking system is a limited early epic that only allows you to book travel if you want: In the above example, we would actually build and release the solution specified, with a very small amount of potential business, but with a potential goldmine of learning opportunities via feedback loops from the actual use of our system.
Try use cases instead of user stories Agile and Scrum brought a different format for writing requirements: As a bank customer, I want to withdraw cash from my account, so that I can buy things from people who only accept cash.
Seen in isolation, this is a nice and brief way to write a requirement. Now, consider this user story: As a bank customer, I want to key in my own personal 4digit pin code, so others cannot get access to my account.
Suddenly we are very detailed, and now have two overlapping user stories on two very different levels.
And while there are guidelines to prevent this — including INVEST stories should be Independent, Negotiable, Valuable, Estimable, Small and TestableI quite often see people end up with stories that are overlapping and very different in the level of detail, which leads to a sometimes serious lack of overview.
This challenges the common understanding and often leads to programs with no predictability or transparency. What can we do about that?
It will bring back the predictability and the overview, and it will help you slice right. Use cases sound very similar to user stories, and while they have similarities they also have big differences.This dictionary decodes abbreviations and acronyms found in various publications including maps and websites.
