Integrate Costs and Issues into CodeScene¶
CodeScene provides an optional integration to Project Management tools like Jira. The integration has the following pre-requisites:
Issue numbers are included/referenced in the commit messages or pull requests/branch names.
You use labels and/or issue types to distinguish different kinds of work (e.g. Bugs, Features).
When present, CodeScene’s Project managment s integrations let you measure:
Accumulated costs per hotspot and sub-system.
Trends by work type, such as “Planned” versus “Unplanned” work.
CodeScene’s cost analyses let you reason about the technical and organizational findings from a financial perspective. For example, how much time do you spend on defects in your top hotspots? What amount of work is unplanned? And what happens over time?
CodeScene supports multiple cost models depending on the data you have available such as cycle times, story points, or time spent. CodeScene can deduce costs automatically based on your development history, so you don’t even need to have developers reporting their time to be able to get a detailed view of your development costs. We cover all options and provide our recommended setup in this guide. Let’s start by looking at the overall model.
CodeScene’s Cost Model¶
CodeScene offers a breakdown of the development costs on three separate levels: file-, architecture-, and system-level. The file level corresponds to the hotspots, the architecture level accumulates costs on a component/service/module level, whereas the system level presents the cost trend as aggregated for all application code.
Fig. 159 CodeScene calculates cost trends on a file-, architecture-, and system-level.¶
Using CodeScene’s cost model, you get the specific development costs on each hotspot. Use this data to inform re-work decisions and to communicate the costs of technical debt to the business:
Fig. 160 CodeScene calculates cost per hotspot, including both feature and defect data.¶
Calculating Development Costs: the four options¶
There are four strategies, and you need to select one of them depending on what data you have in your project management tool:
Estimated development time: calculate a cycle time for the number of hours from the time an issue entered a specific state until the last commit is done on this issue. The cycle time is then adjusted for the number of hours in a typical work day. That is, a cycle time of 3 days has a cost of 3 * 8 hours. In addition, CodeScene distributes the total costs proportional to the change impact when multiple modules/files are modified for the same issue. This cost model lets CodeScene calculate costs as opposed to rely on time reported in the project management tool, which is often incorrect, incomplete, or both.
Issues: the number of issues associated with a given file or architectural component. Use Issues to get a summary and inspect general trends, but without assessing actual time spent.
Points: the cost of an Issue in /Story points/. Use this option if you keep track of story points and use them to communicate within the organization.
Minutes: the cost expressed in time. This method requires that time has been reported on the specified cost-field in the project managment tool. Use this option if you have accurate data on how much time you have spent on each issue.
Export Cost Data to Excel/CSV¶
All cost trends in CodeScene provides a button that lets you export to a CSV file and explore further details in a spreadsheet application.
NOTE: The exported data use the internal cost units. For issues and story points, this unit is always the unit of presentation in the graphs. However, for time-based cost units like Estimated development time or Minutes, the exported cost is in minutes. This typically differs from the values presented in the graphs since CodeScene converts them to more suitable visual presentations (e.g. hours, days).

Specify the Detailed Configuration Options¶
Fig. 166 Configure the information you want to retrieve from Jira.¶
External Projects: Select one or more Jira projects that CodeScene will use as data sources.
Cost Field: is used for he cost models Points and Minutes, Select the Jira field that has your cost estimates. If you use Issues or Estimated development time as cost model, then it is not necessary to configure Cost Field and you can leave it as is.
Work In Progress Transition Name: Specify the name of the Jira status that indicates that the development work has started. Often, this is the “In Progress” or “In Development” state.
The Work In Progress Transition Name is relevant for two analyses: 1. If you use Estimated development time as cost model, then this field is mandatory. 2. Delivery Performance: if you have enabled the delivery performance module, then this config option is needed to calculate lead times.
Supported Work Types should correspond to the different kinds of issue labels defined in your Jira project.
Defect Work Types: specify the JIRA labels or JIRA Issue Types that will be regarded as defects. This configuration is used to calculate defect densities and work type trends.
The Rename Work Types field allows the work types to be mapped to different analytical categories that you can define yourself. How you do this depends on the type of analysis you wish to perform.
Tip: Rename Work Types to distinguish Planned and Unplanned work¶
When looking at cost trends, the most interesting distinction is typically between Planned- versus Unplanned Work.
By specifying Rename Work Types option, the Jira labels are translated to the specified label before being sent to CodeScene. For example, if your Jira project contains Feature and Documentation labels, like in the illustration above, these can be categorized together as Planned Work, while Bug and Defect are treated as Unplanned Work; the Refactoring label – which doesn’t have a translation – will be sent as is. Mapping labels this way can allow you to see more meaningful trends. You are free to map labels however you like depending on your analytical needs.
Advanced Information¶
Measures to reduce bias in the trends¶
Let’s face it: Project management data can be noisy. CodeScene reduces as much of this noise as possible via its data cleaning:
Cycle time in development: improve the precision by identifying issues that have a transition to “In progress” _after_ the last commit related to that issue. CodeScene then fall back on using the date of the first commit as starting point to recover part of the cycle time.
Issues that lack a cycle time: even with the previously mentioned fallback mechanisms, some issues might be implemented with just a single commit. Hence, there’s no way of measuring the actual time in development. To avoid losing valuable data, CodeScene applies a default cycle time of one working day (8 hours).
