Comparison, technical detail

q_Pilot vs. BI Tools (Power BI, Tableau): where the limit is

BI tools visualise data that someone has modelled in advance. That is the right approach for standard reporting. It is not enough for the questions that decide daily work in QC and QA: where work is queuing, which batch is at risk, and what shifts when an instrument fails. These are flow questions, not reporting questions.

What a BI tool does

A BI tool connects data sources, builds a data model and displays key figures. It shows what is defined in the model. Every new question requires an adjusted model and someone to build and maintain it.

In a regulated environment this adds effort that is often underestimated:

  1. Data integrity: Who owns the model, and how is the origin of each figure traceable?
  2. Change control: Every new KPI or calculation logic is a change that may need assessment and documentation under the QMS.
  3. Access rights: Roles for QC, QA and manufacturing must be separated and maintained.
  4. Interfaces: LIMS, Excel and planning data must stay consistently connected over time.

What a dashboard does not answer

A dashboard shows states and trends. Lab control follows a different logic. Lead time results from the ratio of work in progress to throughput (Little's Law). To reduce lead time, you need to understand WIP and bottlenecks, not only display lead time.

Typical questions a standard dashboard does not deliver:

  1. Which method or instrument limits throughput over the next two weeks?
  2. How does the release date of batch X shift if instrument Y is down for three days?
  3. Why does throughput fall while utilisation stays the same?
  4. Which batches are at risk today, before the delay becomes visible?
  5. Where do waiting times occur between sample receipt and release, and what share do they have in total lead time?

All of these can be built in a BI tool. But the flow model, capacity logic and forecast must be built first. That is a project, not a report.

What q_alizer with q_Pilot does differently

Management Hub provides the standard KPIs from the start, for example lead time, WIP per analyst and throughput, without manual extraction from LIMS or Excel. A BI project for this part is not needed.

When a BI tool remains the right choice

For company wide reporting across finance, supply chain and production, a BI tool remains the suitable choice. q_alizer does not replace it. It covers the part a BI tool reaches only with high modelling effort: the operational control of QC, QA and batch release.

Five questions for the decision

  1. Who builds and maintains the data model in three years?
  2. How long does it take from a new question to a reliable answer?
  3. Can the system forecast a release date, or only show the current state?
  4. How is the origin of each figure traceable?
  5. What effort arises with every change to the calculation logic?
