how we work

The Assembly way: structured modernization for growth

Three clear steps keep risk low and momentum high.

phase 1: align

Start with clarity and confidence

Align on what matters - priorities, outcomes, and the path to execution.

✅ Modernize based on real business value, not just tech debt
✅ Get business and tech stakeholders on the same page
✅ Identify system friction that slows growth and agility

phase 2: build

Modernize with speed and structure

Scale delivery based on impact, not guesswork

✅ Break down legacy systems and fix what matters most
✅ Ship in small, trackable increments tied to business value
✅ Keep spend, performance, and governance in sync

phase 3: evolve

Evolve with momentum

Move from reactive fixes to continuous, business-led improvement.

✅ Optimize performance and resiliency based on real-world use
✅ Expand features and integrations aligned to growth goals
✅ Maintain governance and scale without adding complexity

FAQ

00

Absolutely. We slot in as an extension of your team—sharing code, pairing on pull requests, and handing off everything with full documentation.

01

Most projects start with a 4-6 week blueprint phase. From there, implementation timelines vary: a few months for focused updates, up to 6-12 months for large-scale transformations. We work in short, testable sprints - so you see progress in as little as 90 days.

02

That’s exactly what our Accelerators are designed for - short, focused engagements that tackle high-impact areas without a full rebuild. Whether it’s modernizing a backend service, refactoring a legacy feature, or setting up a new integration, we help you move quickly and deliberately.

Our broader modernization approach is modular by design, so we’re used to working with complex systems one piece at a time. We meet you where you are—prioritizing what matters most and helping you build momentum, not technical debt.

03

Most engagements start with a fixed-price Blueprint Phase, typically beginning at $60,000. During this phase, we assess your current application, align with stakeholders, and define a phased modernization roadmap that’s grounded in business goals.

From there, we move into sprint-based implementation, delivered by cross-functional pods. Build Phase sprints start at $25,000 per two-week increment. These pods scale in size and scope depending on your needs—from focused fixes to full-platform transformation. We match team investment to your goals—so you only commit to what’s needed, when it’s needed.

04

Quality is part of every phase of delivery - not an afterthought. We use automated testing as a baseline, including functional and regression tests, plus integrated security scanning (SAST, DAST, SCA) to catch vulnerabilities early.

Our teams apply test-driven development and behavior-driven specifications to ensure new features work as expected and meet user needs. Dedicated quality specialists work alongside engineers and product leads in every sprint, with continuous integration pipelines ensuring reliability across the board.

This tight integration means fewer surprises at launch - and a foundation you can build on confidently.

05

Yes. Post-launch support is built into our Evolve Phase, which focuses on helping your application continue to deliver value long after release.

We offer a range of services - from performance tuning and security updates to ongoing monitoring, light enhancements, and prep for future roadmap phases. Our support is tailored to your internal capacity and needs - so whether you need hands-on help or just a strategic safety net, we’re there.

Our goal isn’t to hand off and disappear—it’s to leave you with a modernized platform that continues to evolve with your business.

06

We’re a Microsoft partner, and much of our work is built around Azure-native services - .NET, App Services, Azure Kubernetes Service (AKS), SQL, Cosmos DB, and serverless functions.

On the front end, we specialize in modern SPAs like React and Angular, using tools like Cypress for test automation. We bring deep experience across cloud architecture, DevSecOps, system integration, and security. Our delivery toolchain includes GitHub Actions, Jenkins, TeamCity, and Octopus, and we follow strong DevSecOps practices with built-in SAST, DAST, and SCA.

Most importantly, we adapt to your existing tech stack and enterprise architecture - we don’t impose one-size-fits-all tools or frameworks.

07

We start in the Align Phase by bringing business and tech stakeholders together to define goals, success metrics, and constraints. Through working sessions and prioritization workshops, we ensure we’re solving the right problems first.

Throughout delivery, we stay aligned through business-facing specs, product ownership, and regular demos. Our cross-functional teams - spanning product, strategy, design, and engineering—make every decision in context of business value, not just code quality.
