Many teams get stuck choosing between massive rewrites (unrealistic) or good intentions (unsustainable). There's a better way that gives you concrete answers while making the work genuinely satisfying. 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!

Software problems are human problems in action 🛠️

Gabriel helped a client turn observability from weakness to strength. The technical wins were important—structured logging, easier queries, stakeholder dashboards.

But the lasting impact came from treating it as a team capability, not just tooling. Extensive docs, demos, knowledge transfer sessions. Because the best technical solution is worthless if it leaves with the consultant.

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 đź’š

From "don't make mistakes" to "let's manage them better" is a journey. One mindset leads to burnout and blame. The other leads to automation, better processes, and actually sustainable software delivery. Guess which one works? https://link.testdouble.com/9a7f27

Product transformations stall when organizations try to change behaviors without first naming them. Product Consultant Michael Toland reminds us: you can't transform culture without codifying what it means in practice.

Principles codified into daily decisions. Not posters. Tools.

Real codification means principles that constrain + trade-offs that acknowledge tension.

Without this foundation, autonomy becomes chaos. https://link.testdouble.com/4613ca

Being a founder is hard—getting to a validated MVP as a non-technical founder can be confounding. Find out how we helped a resource-constrained physical therapy startup iteratively test and learn:
- idea validation
- feature discovery & prioritization
- efficient development cycles

When you're weighing a legacy app rewrite vs refactor decision, think about what stays and what no longer serves the business.

Not everything needs to move forward into a new or updated system. Staff Consultant Steve Jackson points to considerations on cutting scope as one big factor that could align with a rewrite. Careful consideration with your product team could open up possibilities.

Still think C# is just for enterprisey Windows software? 🤔

The .NET ecosystem has reached that sweet spot where you can find well-maintained libraries for most common use cases, but it's not so fragmented that every project requires 50+ dependencies.

Mature ecosystems let you focus on business problems instead of reinventing wheels. Sometimes boring and stable beats cutting-edge and chaotic.
