BA’s scope of work includes developing documentation of different levels: from business (high) level to software details of the development level. At the beginning of the new project development or separate epic task of the current project is comfortable and informative enough to apply such instruments as a user story and acceptance criteria. These short but informative ‘guides’ help to understand the main aim of the client`s requirements and true scenarios of their implementation. User story is a minimal unit of finite goal but not some variant of a possible scenario. A User story is a description of the functionality of the software in a simple, general description, written from the point of view of the end-user or customer. User Stories mostly used in flexible methodologies like Agile is.
The basic formula of the user story consists of the next coherent steps: “User-Action-Aim”.
Let`s discuss some examples.
User
(Actor of the definite functionality or system)
Action
(Action of User with the system)
Aim
(Goal or Business value, that User is going to get)
User of phone
Wants to click camera pictogram on the phone screen
To make a photo
User of web-store
Wants to look through available goods in the definite city store
To pick them up from the store
User of CRM system
Wants to click ‘Save’ button
To save data
Thus, User stories are:
It`s important to understand the appropriate result of the implementation of user stories. In this case, BA describes acceptance criteria for each user story - what should be done(system response).
The basic formula of acceptance criteria includes steps: “Given-When-Then”
Some examples of earlier described user stories.
Given
(Preconditions)
When
(User performs some action)
Then
(System`s response)
Phone screen is active
User clicks on the camera pictogram
Camera application is loaded
Web store page with goods is displayed
User clicks filter of city store availability
Goods list is filtered by the system according to city store availability parameter
Add fofm with populated data is displayed
User clicks ‘Save’ button
Data is saved and displayed on view page

Discussing positive points we can admit:
At the same time, we have to attribute to the disadvantages next details:
User story and acceptance criteria give the basic description of the client`s functional requirements. It`s a rather simple and easy for understandable method. At the same time, as it is a high level of description, the IT team should be experienced enough in the domain of the project to estimate requirements correctly. These instruments don't focus on details but on main functional results. After a basic main scenario is confirmed, BA continues work with UI, UX, and various details functional requirements.
