What this resource helps you evaluate
industrial automation teams renewing supervisory control and visualization systems using a weighted scorecard to select a SCADA Modernization Platform vendor.
A vendor scorecard is useful only when criteria reflect the real operating risk. Weight tag migration, communications, alarming, historian integration, HMI and redundancy, implementation capability, commercial terms and support separately so an impressive demo cannot hide a poor deployment fit.
What to compare first
- Critical workflow fit and exception handling
- Architecture, integration and data portability
- Security, resilience and administrative controls
- Implementation team, references and support model
- Three-year economics, contractual flexibility and exit risk
Step-by-step process
- 01
Agree scoring weights before receiving final proposals.
- 02
Require evidence or a scripted demonstration for every high-weight criterion.
- 03
Score product fit and implementation partner capability separately.
- 04
Record assumptions, gaps and commercial dependencies beside each score.
- 05
Run a final risk review on the highest-weight gaps before approval.
Common mistakes and risk checks
- treating a SCADA upgrade as a graphics project instead of an operational change.
- Comparing headline license price without implementation, integration, migration and support cost.
- Scoring demos instead of validating the highest-risk workflows with real data and users.
Documents and evidence to collect
- Weighted scorecard
- Demo evidence notes
- Gap and workaround register
- Commercial comparison
- Reference-call notes and risk register
Questions to ask vendors
- Can the vendor demonstrate tag migration, communications, alarming, historian integration, HMI and redundancy with our representative data?
- Which capabilities require paid modules, services or third-party products?
- What data can we export in a documented format if we leave?
- What implementation work is performed by the vendor versus the customer or partner?
- How are support response, releases, backups and security responsibilities defined?
