Effective Communication Strategies for Architecture Refactoring Projects

Architecture refactoring is a major, long‑lasting effort that consumes development and testing resources and inevitably impacts feature delivery, so launching such a project requires extensive lobbying and communication with stakeholders to build consensus and avoid unnecessary disputes.

The principle is simple, but the execution is critical.

Technical teams often cite terms like scalability, reliability, performance, coupling, and messy code, which non‑technical colleagues find incomprehensible, leading to miscommunication.

Examples include developers saying the system’s scalability is poor, product staff confusing “scalability” with unrelated concepts, reliability being described as “3 nines vs industry 4 nines,” and coupling being misunderstood as a metaphor rather than a design issue.

These examples illustrate that many technical terms are hard for cross‑functional audiences to grasp, making agreement difficult.

Another common problem is speaking based on feeling rather than data; for instance, claiming that coupling reduces development efficiency without supporting evidence.

The key is to translate technical language into plain language and back arguments with facts and data.

In the M system, “scalability” was reframed as “slow version development” and data was collected showing lengthy design phases, short development windows, and few releases, highlighting the bottleneck.

In the S system, instead of citing reliability in nines, incident counts, downtime duration, affected users, and customer feedback were gathered and compared with other systems to demonstrate reliability issues.

If these tactics still fail, escalation to higher management may be necessary, even issuing firm statements that lack of resources will lead to future failures.

Beyond upstream and downstream coordination, refactoring often requires collaboration with other systems; technical common language helps but resistance still arises from concerns about personal benefit and urgency.

Framing the request as selfish or using vague higher‑level benefits is ineffective; instead, adopt a strategy of empathy, win‑win outcomes, and long‑term focus.

For example, the M and C systems shared a database; the refactor proposed replacing direct DB writes with API calls, which addressed C’s pain points such as data errors, synchronization effort, and dual‑database maintenance, ultimately delivering clear benefits.

When a change benefits the company but not a specific team, higher‑level management may need to intervene.

Claims of “not urgent” are often excuses; applying the same benefit‑focused approach can help address them.

If another business truly takes priority, it’s acceptable to postpone the refactor but a concrete start date must be set (e.g., three months later) rather than vague timelines.

Flexibility in planning—such as postponing certain refactors and handling them in phases—allows better risk management and scheduling control.
