Three sources, three biases

All public data on enterprise solutions is biased. The point is not to avoid biases but to cross-reference them systematically.

Analyst firms

Gartner, Forrester and IDC are essential sources, but their business models create structural bias: vendors pay to be included, evaluations favor incumbents and positioning criteria do not always reflect what happens in the field.

Community platforms

G2, TrustRadius and SelectHub provide valuable user feedback but suffer from representation bias: overrepresentation of North American SMBs, underrepresentation of European mid-market, incentives skewed toward positive reviews.

Vendor documentation

Vendor materials are comprehensive but sales-driven: weaknesses are omitted, roadmaps are embellished, showcased use cases are the most favorable. The buyer never gets a neutral view.

Lean Vectors

First independent EPM and PPM comparator since 2020. Systematic cross-referencing of all 3 source types, field experience from 16 years of engagements, over 9,000 recommendations generated. Transparent and sourced scoring, quarterly updates.

Scoring methodology

MOST REQUESTED

Launch the EPM comparator

15 solutions, 40 criteria, results in 5 minutes

Total independence. Zero conflict of interest.

No commercial ties with vendors

Lean Vectors receives no commission, no free license, no resale partnership from any evaluated vendor. Scores reflect our analysis, not a business deal.

Open methodology

Every score comes with a sourced justification. Sources are dated. Discrepancies between sources are flagged. You see exactly how each score is built.

Quarterly updates

Analyses are reviewed every quarter. A vendor that improves sees its score rise. A vendor that stagnates sees its score drop. No frozen scores, no historical favoritism.

"We are not a marketplace. We don't resell licenses. We have no financial interest in you choosing one solution over another. Our only interest is that you choose the right one."

What the comparator will not do for you

The comparator produces an argued shortlist, not a final choice. It does not replace an RFP, negotiate commercial terms or validate technical fit with your IS. That is what the scoping phase is for.

Frequently asked questions

Is access to the comparators free?
Yes. All comparators and the AI architecture guide are accessible without registration. Only the personalized PDF export requires a professional email.
How often are scores updated?
Systematic quarterly review. Major events (vendor acquisition, pricing change, new version) trigger an ad-hoc update. Each score displays its last review date.
How are scores calculated?
Each solution is evaluated across 40 sub-criteria grouped into 8 categories. Scores (1 to 5) result from cross-referencing analyst sources (Gartner, Forrester), community data (G2, TrustRadius) and vendor documentation. The full methodology is available on the dedicated page.
Does the comparator replace an RFP?
No. The comparator produces an argued shortlist. The selection process (RFP, gap analysis, POC, tender board) remains essential to validate fit with your specific context. That is our core business.
Can I adjust the criteria weights?
Yes. Profiling adjusts the weights automatically based on your context. You can then manually adjust each slider. The ranking recalculates in real time.
Is profiling data shared with vendors?
No. Profiling data is not transmitted to any third party. It is stored only if you export the PDF, with your explicit consent, to enable personalized follow-up.
