Tracking Technical Debt with TechDebtAttributes

Technical debt can build up over time, slows down development speed, and could increase the risk of defects.

If you work in situation where it’s not always possible to create clean code or you’ve inherited a legacy application you may wish to start cataloguing where and how painful tech debt is.

Introducing TechDebtAttributes

I just released an initial NuGet version of an open source project called TechDebtAttributes.

It allows attributes to be used to mark classes, methods, etc as containing technical debt.

When the [TechDebt] attribute is applied you need to specify 2 mandatory values: pain and effort to fix.

Pain is a relative measure of how painful the tech debt is; for example how much it slows you down when changing code, how unhappy you are with it, how many defects are caused by it, etc.

Effort to fix is also a relative measure of the ease, amount of effort/time it will take to fix and remove the debt.

Optionally a description of the debt can also be specified.

Once attributes have been applied, a (string) report can be generated:

***Start of Tech Debt Report - finding all [TechDebt] attribute usages

Benefit to fix: 4999.5  AnotherExampleUsageAssembly.Mango Pain:9999 Effort to fix:2
Benefit to fix: 1666.7  Void .ctor() Pain:5000 Effort to fix:3
Benefit to fix: 5 Quick fix to stop stupid stuff happening sometimes Void SomeMethod() Pain:5 Effort to fix:1
Benefit to fix: 2  ExampleUsage.SillyEnum Tomato Pain:47 Effort to fix:23
Benefit to fix: 0.5 What kind of cheese is this? ExampleUsage.Cheese Pain:3 Effort to fix:6
Benefit to fix: 0.4 What exactly is inner cheese ExampleUsage.Cheese+InnerCheese Pain:3 Effort to fix:8
Benefit to fix: 0.3 This really is silly ExampleUsage.SillyEnum Pain:2 Effort to fix:6
Benefit to fix: 0.2 This is dumb, we should remove it ExampleUsage.ISomeDumbInterface Pain:10 Effort to fix:44
Benefit to fix: 0.1 This should be moved to it's own interface Void Y() Pain:10 Effort to fix:100
Benefit to fix: 0 There's a lot of work to fix this whole class for not much gain ExampleUsage.SomeThing Pain:1 Effort to fix:200

***End of Tech Debt Report.

You can also use a method to specify the maximum total pain you’re willing to accept, if the total pain from all [TechDebt] attributes exceeds this an exception will be thrown and your test will fail.

    Great idea!
    Gonna try to integrate it into CI pipeline (TeamCity)

    Thanks for that.

    Good idea, but my boss would kill me if i'd mark everything with this "this is bad"-attribute...
