Case Study: How JCA Electronics uses Awesome Graphs for Bitbucket to Analyze Code Review Practices and more

This is a fantastic plugin, really useful to monitor individual repo activity or a developers activity across multiple repos. Looks and works great!

JCA Electronics specializes in designing and manufacturing electronic control systems, which are used by original equipment manufacturers (OEM). Their engineering team creates embedded drivers, embedded application software, mobile application libraries and mobile applications for many OEMs that are mainly agricultural and construction companies. The team uses Bitbucket Server for collaborating on code and extended the platform with the app Awesome Graphs for Bitbucket Server to:

  • get the history of developer activity across all projects and use it for filling in timesheets
  • browse commits of all branches of a repository
  • analyze project activity and the process of code review

Data for billing – a click away

JCA Electronics’ engineers can be working on many projects simultaneously. So to fill in timesheets for billing, the company needed an easy way to see a daily work log of each developer. They found Contributions in user profile invaluable for this purpose, as this page shows a developer calendar of the past year. When you click a day, the activity stream shows the list of commits and pull requests across all projects for that day.


Commits across all branches

JCA Electronics appreciates the capability to see the activity across all branches (‘Show all’ link) on the Commits page of a repository or project. Before, they could only view commits of each branch individually.

In addition, there’s a commit graph that gives a visual representation of the development flow and makes the commit log easy to read.

Project activity – at a glance

The team uses project graphs and reports to analyze project activity and monitor the number of contributors. Graphs’ Activity tab provides the charts that let you compare the input (number of commits and pull requests) from the most active developers. It also features the activity stream with the feed of commits and pull requests of the project.


Contributors tab captures the dynamics on two levels: team efforts (green graph) on the project and contributions of individual engineers (cards with red graphs).


Contributors page can show graphs in commits, lines of code added or lines of code deleted. So a project manager can analyze the progress of development from different perspectives.

JCA Electronics also uses Top Committers Report to see what developers worked on a project during a certain period of time, e.g. a sprint, a year, and compare the amount of commits each person contributed.

Insights about code review practices

The company has many projects and repositories to manage. So it is very important for them to make sure that pull requests and code reviews are utilized on each project. Activity in project graphs and Created vs Merged Pull Requests Report help the team ensure that the correct practices are being used.

Activity shows:

  • how many pull requests were created, merged and declined in the project within a chosen time period
  • who made those pull requests, including whose pull requests were declined
  • what developers were more active than others

Created vs Merged Pull Requests Report visualizes the dynamics of pull requests’ creation and merging, which tells the team:

  • pull requests are used a lot (the curve is rapidly heading away from the Time axis) or not
  • more pull requests are being created than merged (red parts of the graph) or vice versa
  • how many pull requests were created and merged in each period

Awesome Graphs app provides JCA Electronics with the capabilities that enrich and facilitate their experience with Bitbucket Server. The company benefits from graphs and reports that give insights into project activity and code review practices, and provide data for billing and evaluation of contributions made by teams and individual developers.
