Evolve your application at the pace of your business
New features, UX redesign, performance optimization, third-party integrations, a dedicated team that transforms your backlog into delivered value, sprint after sprint.
What is evolutionary maintenance ?
Evolutionary maintenance, also known as evolutionary AMS (Application Management Services) or application enhancement, involves evolving your existing application to meet new business needs, integrate new technologies, or improve the user experience.
Unlike corrective maintenance, which fixes what is broken, evolutionary maintenance builds what does not yet exist: new features, business modules, integrations, and UX redesigns. It is a growth investment, not an operating cost.
At TheCodingMachine, we organize it into 2-week agile sprints with a dedicated project manager who is also a developer to maintain momentum and technical relevance.
When do you need evolutionary maintenance ?
Your market is evolving and your application must keep up
Your users are demanding new features
You need to integrate a new tool (CRM, ERP, third-party API)
You are launching a new offer or a new segment
You need to scale to absorb growth
You want to modernize an aging stack
What evolutionary maintenance covers
New features
Design, development, and deployment of business modules that meet your new needs or those of your users.
Performance optimization
Reduction of loading times, SQL query optimization, caching, and refactoring of bottlenecks.
UX / UI Redesign
Interface modernization, user journey improvement, design systems, responsive redesign, and accessibility.
Technical modernization
Framework migration, major version updates, transition to the cloud, containerization, and strategic technical debt management.
From idea to production in 4 steps
An agile approach proven on 500+ projects, designed to minimize risk and maximize the value delivered in each sprint.
Scoping & backlog prioritization
We structure your needs into user stories, assess the effort and value, and define the roadmap for the next 3 to 6 months with you.
Development in 2-week sprints
Daily stand-ups, end-of-sprint demos, and incremental delivery. You see the value grow every 2 weeks.
Testing, acceptance & deployment
Automated testing, user acceptance testing, deployment via CI/CD pipeline with possible rollback. No surprises in production.
Measurement & iteration
Tracking of business KPIs, analytics, and user feedback. We continuously adjust the roadmap based on what we learn.

Questions about evolutionary maintenance
Can you take over an application you didn't develop ?
Yes, it’s actually quite common. We start with a code audit (quality, technical debt, security, performance) that typically lasts 5 to 10 days. This allows us to accurately estimate the onboarding effort and identify priority tasks before making any enhancements.
What is the minimum budget to get started ?
It all depends on the chosen model. In sprint capacity, the typical starting point is 10 to 15 person-days per sprint (i.e., 1 part-time developer). Under a fixed-price enhancement model, we handle projects starting from 30 person-days. We can also start small with an audit or an MVP to validate the collaboration.
How do you prioritize backlog enhancements ?
We use a value/effort matrix (like RICE or MoSCoW) co-built with you. At each quarterly review, we readjust based on user feedback, market changes, and business KPIs. Prioritization always remains in your hands; we provide the technical guidance.
Are you eligible for the Research Tax Credit (CIR) or Innovation Tax Credit (CII) ?
Yes, TheCodingMachine is CIR and CII certified. For enhancements with an innovative component (specific algorithms, AI, new architectures), you can recover a portion of the fees as a tax credit. We provide all the necessary technical documentation.
Can evolutionary and corrective maintenance be combined in the same contract ?
Absolutely, it is actually the most common format. This is referred to as full AMS (Application Management Services), covering corrective + evolutionary + preventive maintenance, with a budget envelope that can be adjusted between the types depending on the context. You remain in control of the allocation.
How do you guarantee the quality of the enhancements ?
Automated testing (unit + E2E), systematic code reviews, continuous integration, pre-production environments identical to production, and user acceptance testing. Each project manager is also a senior developer.
