This is a lightweight application to build Kanban CFD graph and shows Kanban item detail for analysis. It allows for extracting data from different provider. Currently it only supports Rally as our company is using it. :P
The graph is by designed to allow showing data grouping by different owner in different tab. The intention is to allow each owner to compare their graph to the overall or other owners' statistics to see where they can see the problem from. I think this encourage each owner to see same graph with different insight.
Below are some sample screens to illustrate its functionalities.
Shows item lead time by specifying the Start and End stage you defined in Kanban system with Median and Mean lead time calculated. You can further filter the items to show based on a lead time threshold.
When you mouse over an item, it will further tell how long it spends on one stage and even how long it's blocked for any particular reason.
Shows the comparison between estimate time, lead time and lead time without considering blocking duration.
This graph is showing blocked statistics grouped by Kanban stage and blocked reason. In order to not blowing the graph, the blocked reason is probably best to limit to particular category, say Priority Switched, Prod Support, Resource Limited, Env Down, etc.
Note:
-
Button "Load historical data starting from" only takes start date for initialization. It loads item detail & snapshot from that day to today.
-
Button "Reload Data" refresh graphs based on the start & end date from the data loaded before.
Cumulative Flow diagram is cumulative by its nature and most systems do not support directly. Even if some system has historical data query (like Rally), it wouldn't be efficient to query and build the graph fast enough using historical data especially the graph period is long.
This application runs a schedule job at configrable time daily to capture a snapshot of Kanban Item Status in the system (say, Rally). The snapshot data is the foundation of CFD graph.
File server\config.js presents all of the configrable options which is data provider independent.
All of them should be straightforward as comment is provided.
You should only need to change user account & project related setting in server\dataprovider\rally.js.
var rallyUser = ''; // Rally account name
var rallyPassword = ''; // Rally password
var lookbackPageSize = 2000; // Rally API page size
var wsPageSize = 100; // Max is 100
var workspace = 123456789; // Rally workspace id
var project = 987654321; // Rally project id in workspace
var kanbanFieldName = 'c_KanbanState'; // Your Kanban customized field nameYou have to write a customized data provider class yourself.
The data provider only need to provide below API:
- getHistoricalKanbanStatus
getHistoricalKanbanStatus is called when you want to extract data from your system to this app. It should normally be called once as later it will have schedule job to do the work for you.
It expects to have a single date string input. Its output expects to be a Promise which resolves to be an array of below object:
{
objectID: , // Unique Kanban item Id
type: , // Kanban item type matches the keys of kanbanItemTypes
name: , // Kanban item name to show in Item Detail graph
owner: , // Kanban item owner,
estimate: , // Esimated time used to mearure against lead time
statusChangeLog: [{
from: ,
to: , // from & to value should be ISO format date string
status: // Kanban status name matches the kanbanStatusNames
}], // List of object describes the Kanban status period
blockLog: [{
blocked: , // true or false to indicate it's blocked or not
stage: , // At what Kanban stage it is blocked
time: , // the time at which it's marked as blocked or unblocked
reason: // blocked reason
}],
kanbanizedOn: // Earliest time this item is in Kanban System
}$ bower install
$ npm install
$ node index.js
Check the Kanban CFD graph through the server URL and port as you configure in server\config.js. For example:
http://localhost:3000
