DRY + KISS: Deliver Minimal, Valuable Solutions

Software and process design often drift toward feature bloat and complexity. Two simple guiding principles prevent that: DRY (Don't Repeat Yourself) and KISS (Keep It Simple, Silly). Used together they focus teams on delivering the minimal viable solution that solves the problem without unnecessary engineering or ongoing maintenance cost.

This short article explains the philosophy, why it matters for SMBs, and provides a pragmatic checklist for designing and delivering simple, effective solutions.

Why DRY + KISS matters

Cost: Simpler systems are cheaper to build, host, and maintain. Every extra layer of complexity increases cost exponentially.
Speed: Teams deliver value faster when they avoid reinvention and over-engineering.
Resilience: Smaller, well-scoped systems are easier to test, debug, and recover.
Future-proofing: Minimal, well-factored solutions are easier to change than large monoliths with duplicated logic.

Bloat is not just about extra features; it's duplicated logic, overlapping integrations, and customizations that could be handled by configuration or simple rules.

Practical rules (apply before building)

Define the smallest measurable outcome

Start with a clear, testable success metric. If you can't state the outcome in one sentence and a KPI, pare back the scope.
Ask: can this be solved with configuration or existing tooling?

Prefer configuration, templates, and SaaS connectors. Only build custom code when there is a clear, repeatable business need.
Don't copy-and-paste logic

If two places need the same behavior, centralize it — one source of truth. DRY reduces bugs and ongoing maintenance.
Keep interfaces and contracts tiny

Small, well-defined interfaces (APIs, data models) reduce coupling and make integration predictable.
Limit scope with intentional phases

Ship a single module or workflow first. Add another only after the first delivers measurable value.
Automate the repetitive but keep the complex human-driven initially

Automate high-frequency, low-variance tasks (notifications, routing). Keep rare, high-judgement tasks manual until data justifies automation.

Minimal design pattern (MVP approach)

Map the current process in one page.
Identify the one friction point with highest frequency/impact.
Implement the smallest change that removes that friction (a form, a template, a webhook).
Measure: collect simple metrics for 30–90 days.
Iterate: refine or extend modules only after you see measurable benefit.

Examples

Instead of building a full CRM integration, start with a form that writes to a shared sheet and triggers a webhook for the top 3 fields you need.
If reporting is required, begin with a simple dashboard using an off-the-shelf BI tool and a single canonical metric, rather than building a custom reporting engine.
Replace duplicated validation code in several modules with a shared validation library or a central API endpoint.

Checklist: ship a DRY + KISS solution

[ ] One-sentence outcome and one KPI defined
[ ] Scope limited to the smallest useful unit of work
[ ] Reuse existing tools/configuration where possible
[ ] Centralized logic for any behavior used in multiple places
[ ] Instrumentation in place to measure impact
[ ] A short feedback loop (30–90 days) to validate the change

Quick wins for SMBs

Replace duplication with a single template or shared validation function.
Use no-code connectors to prototype integrations before coding.
Convert one high-cost manual task into a simple automation and measure time saved.

Final thought

DRY + KISS is a mindset that values clarity over cleverness. It doesn’t mean never building or iterating — it means building less, but with intention. When teams commit to minimal viable solutions and iterate only on proven value, they save money, reduce risk, and deliver outcomes users actually need.
