Client not being able to see what they are actually getting, only though documented models

Client not seeing the system in action until completion

Not keeping up with changes required as business environments change

Maintenance is usually required immediately when a TDLC developed project is implemented. 

Doesn't engage stakeholders

helps ensure that team members do not take the same tasks

easy to see break down of tasks

shows which tasks are ready to take

progress visible

shows who is doing what

are happy with any changes

have a project leader to allocate tasks

are self organising (no team leader)

are a complete team to get the project completed (with the client)

are self determining

do not let team members make decisions

As a shopper I want to view a list of products so I can select some to purchase story: 

Acceptance criteria

• See a thumbnail image for each product
• Click to view details for each product
• Add to cart from the detail page
• Search for a product by name or category
• View products by category

As a website user

According to the Given/When/Then template, the acceptance criteria would be the following:

1. Scenario: User searches for an item by its name
   “Given that I’m in a role of registered or guest user
   When I open the “Products” page
   Then the system shows me the list of all products
   And the system shows the “Search” section in the right top corner of the screen
   When I fill in the “Search” field with the name of existing item in the product list
   And I click the “Apply” button OR press the Enter key on keyboard
   Then the system shows products in the Search Results section with product names matching entered product name
   And the system shows the number of search results in the top of the Search Results section”

As an Administrator, I want to be able to create User Accounts so that I can grant users access to the system.  

1.    If I am an Administrator, I can create User Accounts.

2.    I can create a User Account by entering the following information about the User: a. Name, b. Email address, c. Phone Number d. License Number (Power/Basic/None), e. Account Status (Active/Inactive), f. Reports to (from a list of “Active” Users)

3.    I cannot assign a new User to report to an “Inactive” User

4.    I cannot assign a new User to report to a User if it creates a cyclical relationship (e.g., User 1 reports to User 2 who reports to User 1

5.    The system notifies me that it sent an email to the new User’s email address, containing a system-generated initial password and instructions for the person to log in and change their password.

6.    I am able to verify with the intended recipient of the email that it was received.

means the team can decide on priorities without the client

makes sure the client/product owner has considered what is most important to them

helps the development team understand which parts of the system need to be implemented first

because it's a method for showing how testing should be carried out.
