Visial Web: simulating 50 years of financial and asset trajectories
TCM has been supporting Visial Développement since 2019 in migrating its legacy tool to a collaborative web platform, to manage the asset and financial planning of social housing.
Visial Développement, serving social housing
Representing the French social housing (HLM) movement (nearly 4.8 million homes), the client, Visial Web, needed to migrate obsolete single-user software to a collaborative web architecture, then integrate decision-making capabilities (Business Intelligence).
Three challenges to migrate without regressions
Documenting legacy code
Identifying complex dependencies between features and documenting legacy code with little or no documentation.
Migrating without regressions
Reproducing the existing tool's features identically from the launch of the new platform.
Securing and speeding up the tool
Reducing response times and fixing the existing tool's security vulnerabilities.
A faithful migration to a collaborative platform
The former application, reinvented for the web
TCM developed an application matching the former one but designed for the web, with decision-making capabilities for asset and financial management teams.
Financial and asset projection
Multi-year projection module.
Sharing projections
Features for sharing projections between platform users.
Scalable architecture
An architecture designed to absorb increased load and future developments.

Your questions about asset management in social housing
What you need to know before migrating a business tool to the web, with the example of the platform developed for Visial Développement.
By first documenting the dependencies between features in the existing code, then reproducing them identically before adding new capabilities. This is the approach TCM followed for Visial Développement.
By making it possible to simulate several years of financial trajectories and share these projections between users. For Visial Développement, that means 50 years of trajectories that can be simulated instantly.
TCM (The Coding Machine), a custom software development agency based in Paris, has been supporting Visial Développement, a social housing player continuing the work of the French HLM movement, since 2019 in migrating its asset management tool to the web, in PHP, Symfony and Vue.js.
