Software delivery’s inner and outer loops

How focusing narrowly on developer productivity derailed enterprise software delivery – and how organisations can re-align their inner and outer loops.

DevOps' broken promise

Software delivery is in crisis, as delayed releases and quality failures block enterprise innovation.

Common symptoms like slow testing, unclear requirements, and data bottlenecks undermine productivity and quality. Enterprises struggle to fix the root cause of these challenges. They instead opt for quick-fix solutions, growing reliant on painkillers that provide temporary relief, but do not offer sustainable solutions.

To diagnose and solve poor productivity and software quality, enterprises must understand how their DevOps lifecycle has split into “inner” and “outer” loops.

Inner and Outer Loop Overview - Curiosity Software Smaller
INNER LOOP QUALITY

What is the inner loop?

The inner loop refers to the high-value development tasks associated with creating software, such as coding, solving problems, reviewing and debugging. These activities are essential for the initial creation and refinement of the software code.

The evolution of inner loop productivity

This inner loop has enjoyed sustained investment and innovation, unlocking ever-greater developer productivity:

Code Completion and Software Delivery

1996

Code completion and “Intellisense” introduced to widely available IDEs.

Build automation in Software Delivery

2001

Apache Maven continues advancements in build automation.

Package Management and Software Delivery

2010s

New package managers and code libraries enable lightning-fast code changes.

Artificial Intelligence in Software Delivery

2020s

AI-powered Co-Pilots and Agents further accelerate development.

“92% of U.S.-based developers are already using AI coding tools both in and outside of work.”

The outer loop

What is the outer loop?

Whereas the inner loop is the domain of the developer, the outer loop is the world of the business analyst, product owner, tester and data engineer.

The outer loop drives the initial software ideation, feeds the inner loop with all the high-quality assets it requires, and ensures that software is well-developed, robust, reliable, and ready for real-world use. This involves tasks such as requirements engineering, test case design, test data management, and quality engineering.

 

Outer Loop - Curiosity Software

Inner/outer loop misalignment

Enterprises have invested heavily in inner loop productivity, often at the expense of the outer loop. Yet, a productive outer loop is equally important to the creation and delivery of high quality software.

High-quality assets delivered to the inner loop mean that developers can quickly implement features, fix bugs, and deploy new versions of the software, contributing to a rapid development cycle. A smoothly-operating outer loop enables rapid software delivery, with clear requirements, accurate test data and a reliable testing environment, alongside continuous feedback to ensure that software meets requirements.

When the outer loop becomes neglected and bottlenecked, it creates negative risk throughout software delivery.

Inner and Outer Loop Disparity - Curiosity Software

4 Common symptoms of misalignment

Delayed Releases - Curiosity Software

Delayed releases

Your outer loop relies on repetitive manual work and maintenance when reacting to inner loop changes. Technical debt and blockers mount.
Poor Quality - Broken Release - Curiosity Software

Poor release quality

Rapid development is not traceable to clear requirements. Unmeasured, repetitive tests cannot provide release readiness or confidence.

Misalinged Teams - Missing Piece - Curiosity Software

Misaligned teams

Unclear requirements, silos and miscommunication create rework, while teams must wait slowly for test data, testing and environments.

Talent Turnover - Curiosity Software

Talent turnover

Skilled practitioners want to collaborate on valuable software. Fighting fires, toil and a ”hero culture”, they seek new opportunities.

4 steps to rebalance your inner/outer loops

Where should enterprises start in eliminating inner/outer loop misalignment?

4 benefits of inner/outer loop alignment

kpi

Faster time to market

Traceability to inner loop changes focuses outer loop efforts and automates away toil. Outer loop productivity sky-rockets, focusing on value-added activity.
success

Release readiness

Requirements and quality engineering are measured against inner loop changes. Rigorous tests assure the bug-free delivery of requirements and code changes.

support

Collaboration

Inner and outer loop stakeholders work from a shared under-standing of systems, requirements and quality outcomes, without silos or cross-team constraints.
