Title

Time Constraints Hamper Inner Source Progress

Patlet

TBD

Problem

Project management believes that timeline pressures and feature content commitments do not allow Developers to spend the time needed to develop shareable, reusable code and provide support. As a result, there is currently no code available for reuse, and Developers are writing redundant code.

Context

Customer deadlines and delivery commitments for feature content do not change.

Forces

  • Aggressive roadmaps for delivery
  • Project management concern that engagement will lead to missed deadlines
  • Project management concern that Code contribution and/or mentoring may lead to dilution of subject matter expert time spent on their own projects (other teams may require their time).
  • Elimination of rewriting common code saves time (write once, use many times)
  • Crowd-based testing and debugging saves time (and improves quality)
  • The collaboration and synergy of inner sourcing can generate new, innovative features .
  • Test Driven Development could mitigate some of the above forces

Solutions

  • Known pattern: temporary fork by product team, merging changes back later to component team
  • Known anti-pattern: surreptitious temporary fork, no communication
  • New Pattern: Pre-pull request (prior to release), to ensure component team has buy-in, to avoid breakage for temporary fork
  • Allocate time into Development sprint/release schedules to allow for inner sourcing
  • Provide education to product owners and Development leads regarding time saving benefits of Inner Source

Resulting Context

Time is allotted in the schedule for inner sourcing. Less duplicative development due to availability of reusable code. (No negative impact on customer deadlines or content delivery commitments.)
