A single task can be used by many users in the system for example a Time sheet Entry.By selecting roles , Users can be grouped by the interactions they have in the system, managers, employees, contractors.
Involve all possible stake holders together to develop user rolesUse Index Cards to write down roles.Identify usage by the roles to categorize. For example mobile searcher, geographic searcher, keyword searcher belong to same category whereas advertiser is not.
Come a group and discuss your choices.
Incomplete requirements makes you think If I could encourage people to “think out of the box”, then there is a chance of getting beyond essential requirements.When teams work with User stories they learn pretty quickly to identify the obvious requirements, however building for current market needs will leave the product vulnerable for low-cost, disruptive attacks.
Six MinutesWhat were the User Stories Like?How did this experience compare to previous experiences ?Was this a creative experience ?How can we improve Out of the box thinking in writing User Stories ?
The product may be static but our relationship to it changes based on how we use it.Interaction context switching happens based on lots of factors including when, where, age, experience etc.One of the most used change in context is when, aka time of the day.

Most teams try to split stories by architectural boundaries such as one for UI, one for DB, one for Backend, even though these stories are small they fail the Independent and Valuable step

User Roles User Roles are a best choice for aggregating individual users of a system. A User Role reflects the common interactions of a set of users have in the system.

Interaction Context Interaction Context is a an abstract place in your system that supports number of User tasks (Jeff Patton, Design Thinking) Normally when the goal of the user changes then an interaction context switching happens. Starting Point: give the user a clear starting point for starting a search for businesses in the site. Search Return: Evaluation: help the user decide if the searched for items were the items she was looking for or an easy way to reinitiate the search if not. R. Anantha Narayanan, CSPO, CSP 11
Time of the Day Imagine you are the Users of DLC. In pairs walk over to the Wall Board with Time Frames written down.

Go to each time frame in the wall board and repeat the exercise. R. Anantha Narayanan, CSPO, CSP 12

Investigate credit card processing. Implement credit card processing. R. Anantha Narayanan, CSPO, CSP 20
