User characteristics

  • DHIS 2 related users that want to query a moving average (monthly) for occurrence of different indicators
  • The typical user is already familiar with general statistical functionality

Functional requirements

Statistical functionality:

  • Moving average (monthly)
  • Comparison of two datasets (I.e. same time interval for different years)

Performance requirements

  • Requirements for statistical computation: test front-end computation on monthly datasets for two different years.

Group presentation

How you are dividing tasks within the group

We started with a group meeting, to discuss suggestions for user experience, system architecture and functionality. At the end of the meeting we divided tasks between group members to complete within the next group meeting.

We decided to have a second meeting where we presented the completed tasks, prepare for the costumer meeting and setup this wiki.

We are using kanban development methodology. The iterative development process is as follows:

  1. Pending activities/tasks
  2. Analysis
  3. Development
  4. Testing
  5. Deployment

See "technical discussions" under screenshots/ screen flows below for overview of weekly technical group meetings.

Documented learning during project

Until the 11.11.2016 we focused on the understanding of the Angular2 architecture, Typescript, and the DHIS2 API. We split up into two groups; each group came up with an architecture proposal for the project, which we merged/choose the best parts of both. One group followed the TUTORIAL: TOUR OF HEROES, the other group followed different tutorials on Mean Expert

For further documented learning/ technologies involved during project, see section "System overview"

Suggested improvements to APIs etc

Very good API endpoints and documentation. No further improvements suggested.

The app is deployed at DHIS2 test server: The Group Inc - Moving Average Statistics

Tip: search for organisation unit "Bo" and indicator "Complicated deliveries total" (contains data on test server)
