This is Part 5 in my series of posts on Event Discovery. The technique I present in this post is very effective in cases where you know little or nothing about the business area under study.
Using the methods presented in my prior posts, you are able to discover Entities (e.g. “Customer”, “Sale”, “Store”, etc.) for which you need to store persistent data. As you flesh out the data needs for each Entity, here are some powerful questions that enable you to discover more events:
- For new data elements (i.e. data that is not currently being captured in the existing system), ask “Why do you need this data? What will it enable you to do?”. The answers will be business processes that can be entered on the Event List. Once you have at least one cell of information for a row on the Event List, you can fill in the rest of the row with the relevant questions. For example, if the new piece of data is “Customer Mobile Phone #”, your business partners may say “We want to conduct text message marketing campaigns”. That answer leads you to the questions on the Event List such as “What Event starts a campaign”, “What is the input data and who/what provides it”, “What are the business processes”, “What are the outputs and who/what receives them”.
- For existing data elements (i.e. data that is currently captured by the existing system) ask “If I took this data away from you, what will it prevent you from doing?”. This is a question that will get your business partners to think deeply about the answer, as the thought of losing something usually heightens awareness. For example, if the data element in question is the Employee Address, this may prompt your business partners to reveal all of the direct mail items sent to an Employee (an example would be “Start or open enrollment for benefits), and these would have corresponding events that initiate them.
The Event Discovery series continues in the next post.
