Directions (Assignment description)
This assignment involves creating an app for DHIS2 that produces visualisations for logistics data, including the necessary calculations for producing these, including:
- For a selection of organisation units, produce a visualisation of the estimated months of stock left. There is usually a policy to keep the stock between a minimum and maximum levels. These should be configurable in the app, and organisation units above/below these levels should be highlighted.
- For one organisation unit, produce a visualisation of the time-trend in stock availability (e.g. for the last 12 months), with minimum and maximum thresholds for what is adequate levels of stock.
The estimated months of stock left is based on the average amount used in recent periods, compared with the stock available at the end of the period in question. For example, if 350 doses of BCG has been used on average Jan-March and 600 doses is available at the end of March, the current stock will last an estimated 1,7 months.
It should be possible for an administrator to set the default minimum and maximum thresholds (in months of stock availability) to be used, and for users to override this. Furthermore, because this app should be usable in different settings/ countries and thus different DHIS2 databases, there must be an interface for selecting what data elements/ indicators to use for analysis, i.e.. for each variable the stock used, ending/ starting balance etc (as needed).
Plating example (Mockup)
- Remaining stock status
- Graph visualisation
- Persistent storage of Min/Max thresholds
- Tree visualisation of organisation units
This is our projected time usage as of now. This is subject to change during development.
- Milestone 1: Wiki page is ready according to project description.
- Narrowing in on the assignment, getting the project more specific. Setting up Vue and ChartJS libraries.
- Working on Input and output from users. Show data from API in chart format.
- Polishing the User Experience. Functionality for saving Min/Max of stocks. Data for estimated stock and time stock will last.
- Final fixes. Getting ready for presentations.
- Since the program is supposed to be used in different settings/countries, we decided to include all data elements in one dropdown menu. This gives the user full access from one single menu.
- Min/max thresholds save the minimum/maximum allowed values.
- Users in the F_PROGRAM_DASHBOARD_CONFIG_ADMIN group are considered administrators. These users have extended rights to modify default thresholds.
To make the project we have ve decided to use these frameworks and external libraries:
Front end framework
As the front end framework we will use Vue. Vue is lightweight and easy to get started with. It also has a considerable amount of modules available for use.
We used vue-jstree for the organisation unit hierarchy view.
For managing dependencies with ease we will use Yarn. We're using Yarn because of ease of use. It's faster than NPM, and allows for good integration with the program itself. We've also added a license-checker package which helps us decide what licenses our dependencies use.
To manage the workload we are using Trello. Trello is great because it makes it easy to divide work between the team members.
For version control we will use git and github.
