Your velocity problem isn't a headcount problem. It's an unclear requirements problem. A technical debt problem. A tooling problem. Hiring more developers to work around broken processes just amplifies the chaos. https://link.testdouble.com/904ed5

Principal Software Consultant Dave Mosher talks about identifying the legacy modernization strategy that's right for you and your codebase. Sometimes a seams path makes sense, and in other cases following a value path is better suited. youtu.be/CMqfSFIUiDU

You need to fight for feedback. We often front-load discovery to feel confident before building—but that's not real agility. Continuous learning reduces risk better than perfect plans ever could. https://link.testdouble.com/5b3945

"I was elated when another engineer mentioned deploying a new dashboard without my involvement."
We don't focus only on the technical solution—we also build team capabilities.
Our approach to observability, and why the human element matters most: https://link.testdouble.com/a882ec
When a wide range of things aren't working or didn't scale effectively, you hit trade off decisions. To make an effective business case for budgeting you need to ensure you're advocating for the right things. Our pragmatic and actionable assessments help you do just that.

The critical things that ensure your software application is maintainable now and in the future are seemingly simple.
Brian Hughes shares two key truths about automated tests and legacy software applications.

Slow delivery isn't usually about your people—it's about your system. Shifting focus to incremental improvements in the system helps change not just processes but behaviors for lasting change. https://link.testdouble.com/09fc66

Healthcare tech teams keep launching features. Tech debt keeps growing. The problem isn't your developers—it's solving symptoms instead of root causes. This report points to possible reasons why. https://link.testdouble.com/389f5e

Many teams get stuck choosing between massive rewrites (unrealistic) or good intentions (unsustainable). There's a better way. An incremental, ratcheting approach can give you more leverage for lasting impact. We offer assessments that can help you find the seams and map out a plan to get started.

The problems most worth solving are often the slippery ones. The problems that are hard to define the edges of. Many thanks to Mike Berkman for contributing insights to our report on healthcare challenges, Symptoms to Sources!

Python type safety lightbulb moment: mypy = compile-time safety Pydantic = runtime safety
Helped a client shift domain knowledge from heads → codebase with this combo. https://link.testdouble.com/769eb9
No more "wait, what does this field contain?" moments 🎯

Staff Consultant Brian Hughes shares why a seams approach to legacy modernization can be even more complicated when seams are crossed.
This introduces multiple possible paths. Luckily for you, we've encountered that before 💚

50+ microservices. Lean team. Daily fires.
The fix:
- Custom logging library
- API gateway architecture
- Structured learning via katas
- Improved Collaboration
50% faster deployments, resolutions in minutes. Software problems are human problems. We speak human. https://link.testdouble.com/1bd181
Product transformations fail when you try to change behaviors without naming them first.
Not taglines. Real principles that constrain decisions. Trade-offs that acknowledge tension.
Example: Quality even over speed.
Without this autonomy becomes chaos. https://link.testdouble.com/e34baf
Increasingly software problems are data problems, and this is especially true in healthcare. Many thanks to Andrew Warner for contributing to our report, Symptoms to Sources!

Complex systems are usually complex for incidental reasons. It's counter-intuitive, but purposefully simplifying can be huge for scaling.

When you're weighing a legacy rewrite vs refactor, consider what stays and what doesn't.
You don't need everything in a new or updated system. Staff Consultant Steve Jackson says cutting scope can align with a rewrite, and deserves review with your product team.

Code is a means, not an end. The code itself is ephemeral. What endures is the solved problem, the working system, the user who can now do their job better.
That's why, while we use AI to solve interesting challenges, we say software problems are human problems.
In healthcare there are so many areas you could choose to solve problems and improve inefficiencies. When you focus on the voice of the customer and improving patient outcomes, that's when you get to bigger impact. Many thanks to Sara Saldoff for sharing insights for our report, Symptoms to Sources.

Product teams at a $6.5B retailer were missing deadlines, engineers quit, and funding was cut 40%.
Focus for the win: 12 initiatives to 5, decision framework, and data-driven culture. Product releases went from 1x/quarter to 2x/month. https://link.testdouble.com/1f52f2

We don't mind working in legacy codebases. In fact, legacy rescues are super rewarding to our folks—because we start by respecting the legacy of that legacy code. More from Dave Mosher on what makes for a good software consultant: https://link.testdouble.com/82e8d1

You can turn observability from team complaint to competitive advantage without ripping out the entire logging infrastructure.
Our approach? Fix the next most painful thing. Build momentum. Transfer knowledge.
