The systems Stimulus signals a new station.
At runtime.
System, presentation.
The user can view the new station / use it
within <1 second.
A user wants to detect the type of deviation (positive or negative) and to assess the amount of deviation easily
at runtime
Presentation, system
The user can view the variance and assess its nature of the deviation and / or amount of deviation
in which he can choose between at least two different presentations (e. g. highlighting values, diagrams, ...).
Update README.md and CONTRIBUTING.md file in order to make the project more accessible and easy to understand for new contributers and spectators.
A user adds a value
during normal operation with 200 users
System, GUI
The variance is presented
within < 0.5 seconds. All presentations are up to date.
As a developer, I want to be able to show and interact with the App without running it locally on the computer.
The developer or maintenance developer Stimulus wishes to create a new GUI
during implementation phase, maintenance phase.
Presentation and interaction
The new GUI is developed, documented, tested and ready
for use
without changing the logic within one day.
Use http-Client with observer pattern in order to receive records from the database on init as well as update data every time new data is stored inside the database
When open the app and new data is stored inside the database
Data is available inside database
List all assessment records inside a table
Observe database for new incoming records
As a developer I want to have different kinds of functionality inside different components in order to make it interchangeable.
Show all assessment records in a list
The system highlights the variance in red when it is 10% or more below the target, or in green when 5% or more above the target.
The system does not calculates no percentages but hard coded conditions.
When a new station was added to the system, this is indicated on the GUI.
A new station is available
The system is running in normal mode.
The new station will be displayed and values may be entered.
New station is integrated like any other station in the
overall system
A GUI has failed by operator, software errors or hardware failure
during normal operation
Presentation and interaction
GUI is available again
within one business day. The system continues to operate normally and other GUIs can be used.
Show all assessment records in a list
When open the app
There are records inside the data base
List all assessment records inside a table
It is possible to select one record in order to edit the data
The developer or maintenance developer wants to deploy a new GUI
at runtime
System
The new GUI can be used
within half an hour. The system continues to operate normally. There is no impact to other GUIs.
Add Behavior Subject to have a single point of truth. Whenever the GET records method is called, all subscribers of this subject will receive the new data.
Every so often staffers go out on an assessment where they go to various stations and note the actual ice-cream particulate concentrations.
Staff receives new particulate concentrations.
System and database are working
Record is updated in the app.
Database updated as well.
The developer or maintenance developer wants to implement and add a new functionality
during implementation phase, maintenance phase.
System logic
The new functionality is developed, documented, tested
and ready for use
within one day. There is no impact to the GUI or the other
functionalities of the system.
The system adds a new station
during normal operation with 200 users
System, GUI
All Users can see the new station
Within <2 seconds
The developer or maintenance developer wishes to test a new GUI
during implementation phase, maintenance phase.
GUI
The developer can develop unit tests for the GUI and run the tests
within one day. The tests can be run automatically.
After adding a new value a user wants to estimate the variance
at runtime
Presentation, system
Variance is highlighted so that.
The user can detect deviations and their type (positive or negative) in < 0.5 seconds.
The system has failed by operator, software errors or hardware failure.
during normal operation
Logic
The system is available again.
within half a day.
The developer or maintenance developer wishes to create a new GUI on a new device
during implementation phase, maintenance phase.
Presentation, device and interaction
The new GUI is developed, documented, tested and ready for use
without changing the logic of interfaces within two days.
