Agentic RAG or classic RAG: when to let AI plan its research?
Letting an agent rephrase, search, verify, and start over can improve complex questions. This also increases variability, cost, and the safety surface.
Prioritizing AI use cases in business: value, feasibility, risk, and ROI
A good first AI project is not the most spectacular. It is the one whose value, data, limitations, and adoption method can be tested quickly.
Internal search engine: full-text, vector, or hybrid — how to design useful results?
Good research does not depend on a single algorithm. It combines the right index, business vocabulary, permissions, interface, and an evaluation method.
SaaS, low-code, open source or custom development: how to choose your business software?
The right solution is not the most modern or the most customizable. It is the one that covers business value with an appropriate level of control, cost, and risk.
GraphRAG, vector or hybrid search: which architecture to connect complex knowledge?
A graph is useful when the relationships carry an essential part of the meaning. It is costly when it artificially reconstructs what a good index already finds.
Preparing your data for generative AI: inventory, quality, rights, and traceability
Most of the difficulties of an AI project appear before the model: unavailable sources, outdated documents, implicit rights, and lack of an owner.
Human in the loop: designing human validation of an AI system without creating a false sense of control
An 'approve' button is not a control if the person has neither the time, nor the evidence, nor the power to refuse.
How much does a custom web application really cost? Calculating its TCO over five years
The initial quote is only part of the cost. A solid decision takes into account maintenance, operation, upgrades, incidents, licenses, and reversibility.
Headless CMS: the real use cases, hidden costs, and decision criteria
Separating the content from its rendering can free up several channels, but it shifts functions that the coupled CMS provided for free to the project team.
Modernizing a legacy application without rewriting everything: strategies, costs, and roadmap
A legacy application is not defined by its age, but by the difficulty of evolving it with confidence. The right strategy combines business value, risk, and transition capacity.
AI Governance: Building a Useful Policy and Registry, Not Another Bureaucracy
A charter without an inventory controls nothing, and a register without decisions quickly becomes obsolete. Useful governance links each use of AI to an owner, boundaries, evidence, and a review cycle.
