Obsolescence Page
With Kiuwan Insights, you can easily explore the versions of the components used by your
...
application.
For every external component, Kiuwan Insights clearly states the version used and provides
...
an Obsolescence Risk indicator.
Information on components’ Obsolescence is accessible through Insights >> Obsolescence tab.
Insights >> Obsolescence displays version-related information on components in several sections:To see this, go to Insights > Obsolescence. This page displays:
- Overall Information on Components – aggregated information on number and type of components
- List of Components – detailed listing of components
- Component detail – detailed information on the selected component
Before explaining the page contents, you should understand some basic concepts widely used throughout the Obsolescence page.
Obsolescence Risk
Any component has a lifecyclelife cycle. This means that at some date it was created and it evolved through different versions during its life time.
...
lifetime.
When Kiuwan Insight detects the use of a component, it displays its Used Version in your application, as well as the date when that version was released (Date).
Also, Kiuwan displays the Last Version (the latest released version of the component) and the date when the last version was released (Date).
...
With these values, Kiuwan Insights calculates two important periods
...
:
- Out of date: the elapsed time between the date of the used version and the date of the latest version (a measure of
...
- the antiquity of your version respect to the latest version)
- Inactivity time: the elapsed time between the date of the latest version and the current date (a measure
...
- of how active is the component)
As you may already guess, high High values for those periods of time are not desirable:
...
| Value | Consequence |
|---|---|
| High Out of date value |
...
| You are probably missing bugfixes and new functionalities that are in newer versions. |
...
| High Inactivity time value |
...
| The component is “dead” and you should |
...
| find some more active components |
...
| . |
| Info |
|---|
Out of Date and Inactivity Time values are converted to a yearly-scale ranging from 0 to 10 years (values higher than 10y are taken as 10). Obsolescence Risk is calculated as a weighted average of Out of Date and Inactivity Time values (converted to years):
|
...
Resulting values of Out of Date, Inactivity Time and Obsolescence Risk are considered as follows:
Value (years) | Label |
0 |  |
( 0, 2y ] |  |
( 2y, 5y ] |  |
( 5y, 10y ] |  |
...
Overall Information on Components
According to the above explanation of concepts, the Obsolescence tab displays the overall obsolecnce obsolescence information of your application.
Overall The overall section displays:
- Number The number of components falling in High-Med-Low categories for Obsolescence Risk, Out of Date and Inactivity Time
- Scatter A scatter plot of the components’ obsolescence
- Alerts on number of several components with High value of Obsolescence Risk, Out of Date and Inactivity Time
...
