From BI to S&OP and DDMRP: revisiting a 2019 Voxlog interview with Supplaï's Gilles Alais

A historical view of planning and decision support

On April 18, 2019, Voxlog published an interview signed by journalist Isabelle Gazzola with Gilles Alais, founder and CEO of Supplaï. The interview covered the recently launched company's approach to supply chain planning, business intelligence (BI) and decision-support technologies. This entry revisits the historical discussion; it does not report a new development in October 2026.

Planning as a decision process, not only a reporting exercise

In the interview, Alais argued that BI should not be restricted to retrospective reporting. He presented it as a component of planning itself, connecting supply chain information with wider financial, marketing and human-resources considerations. This was the interviewee's stated vision, not an independently demonstrated operating result.

Connecting operational planning domains

The discussion identified demand management, production planning, inventory optimization and DDMRP as connected planning activities. Alais also described S&OP as a higher-level process that could benefit from integrated decision-support technologies. The proposed value lay in making information understandable and usable across functions rather than isolating each planning process.

Shared KPIs, common data and simulation

Asked about good and bad practices, Alais cautioned against expecting planners to become data scientists. He emphasized common performance indicators, a shared information base and BI tools incorporating simulation and planning functions. The discussion illustrates that the problem of connecting analysis with operational choices predates the current AI wave.

Dataleo interpretation: what has changed, and what has not?

For Dataleo, the documentary value of the 2019 interview is the continuity of the planning challenge. Modern AI systems may offer different interfaces and analytical techniques, but a useful recommendation still depends on the decision being made, consistent assumptions and an operating process able to act on the result. The trade-off is between richer analytical capability and the risk of adding a new interface without improving planning decisions. Human accountability remains with the people authorized to approve demand, inventory and supply commitments.
