How to Compare Automation Vendors When Every Proposal Looks the Same
You've received three proposals for your automation project.
​
All claim to deliver the same outcome.
All promise reliability.
All mention experience.
​
Yet one quote is significantly more expensive than another.
How do you know which supplier represents the best value, and which could become a costly problem later?
​
For many Project Managers, comparing automation vendors is one of the most difficult parts of the procurement process.
Unlike buying standard equipment, automation projects involve engineering expertise, project delivery capability, technical risk and long-term support. These factors rarely appear clearly in a quotation.
​
At Stratos Control Systems, we regularly encounter projects where buyers are comparing proposals that appear similar on paper but differ significantly in scope, risk and lifecycle value.
Why Choosing the Wrong Automation Vendor Creates Project Risk
Many automation projects fail before engineering work even begins.
​
The supplier selection process has a direct impact on:
-
Project timelines
-
Budget control
-
Technical outcomes
-
Future supportability
-
Long-term system reliability
​
A supplier may appear competitive during procurement but create significant challenges during project delivery if scope, testing and support requirements are not fully understood.
Choosing an automation vendor is not simply a purchasing decision. It is a project risk management decision.
Why Automation Projects Are Difficult to Compare
Most automation vendors can describe what they will deliver.
Far fewer explain how they will deliver it.
​
Two suppliers may both propose:
-
New HMI software
-
Control panel modifications
-
Testing and commissioning
​
Yet the actual project scope, quality standards and delivery approach may be completely different.
This often creates confusion for Project Managers who need to balance budget, risk and delivery expectations.
Why Automation Projects Are Harder to Procure Than Standard Equipment
Unlike standard equipment purchases, automation projects involve:
-
Software development
-
Engineering design
-
Legacy infrastructure
-
Integration challenges
-
Site-specific constraints
-
Operational risk
​
Two suppliers can quote for the same project and still deliver very different outcomes.
This is why procurement teams and plant managers must look beyond price and evaluate the entire project delivery approach.
The Hidden Problem with Comparing on Price Alone
The lowest quote is not always the lowest-cost project.
Unexpected costs often emerge after contracts have been awarded.
​
These may include:
-
Additional engineering hours
-
Change requests
-
Extended commissioning
-
Production delays
-
Additional site visits
​
A cheaper proposal can quickly become the most expensive option if critical work has not been included from the outset.
Why Proposals Often Look Similar
Many suppliers quote from the same tender documents.
If the specification is incomplete, vendors make assumptions.
Each supplier may interpret requirements differently.
​
As a result:
-
Scope varies
-
Risk allowances vary
-
Testing approaches vary
-
Documentation standards vary
-
Support services vary
​
The proposal may look similar while the actual deliverables differ significantly.
10 Questions Every Project Manager Should Ask Automation Vendors
1. What Exactly Is Included?
Request a detailed breakdown covering:
-
Hardware
-
Software
-
Engineering
-
Documentation
-
Testing
-
Commissioning
-
Training
Vague descriptions often hide future costs.
​
2. What Is Specifically Excluded?
The exclusions section often reveals more than the inclusions.
​
Common exclusions include:
-
Network upgrades
-
Third-party integrations
-
Safety validation
-
Operator training
-
Documentation updates
Understanding exclusions helps prevent disputes later.
​
3. How Will Risks Be Managed?
Ask vendors:
-
What project risks have been identified?
-
How will they be mitigated?
-
What contingency planning exists?
Experienced suppliers proactively manage risk rather than reacting to problems.
​
4. What Site Survey Has Been Completed?
Ask:
-
Have they visited site?
-
Have they reviewed documentation?
-
Have they assessed obsolescence risks?
The quality of the survey often determines the quality of the proposal.
​
5. What Testing Is Included?
Testing should cover:
-
Factory Acceptance Testing (FAT)
-
Site Acceptance Testing (SAT)
-
Functional testing
-
Software validation
Insufficient testing frequently creates commissioning delays.
​
6. Who Will Actually Deliver the Project?
Ask:
-
Who will manage the project?
-
Who will write the software?
-
Who will commission the system?
Experience matters.
​
7. What Happens If Problems Are Found During Delivery?
Ask:
-
How are changes managed?
-
How are additional costs approved?
-
How is scope controlled?
Clear processes reduce project disputes.
​
8. What Documentation Will Be Provided?
Documentation should include:
-
Electrical drawings
-
PLC backups
-
Software documentation
-
Network architecture
-
Operating manuals
-
Test records
​
9. What Support Is Available After Handover?
Ask:
-
Is ongoing support available?
-
Are service agreements offered?
-
Can engineers provide future modifications?
Automation systems require lifecycle support.
​
10. Can They Demonstrate Similar Project Experience?
Request examples of:
-
Similar industries
-
Similar PLC platforms
-
Comparable project sizes
-
Successful upgrade projects
Relevant experience reduces project risk significantly.
Download the Automation Vendor Comparison Checklist
Before awarding your next PLC, SCADA or control system upgrade project, use a structured evaluation process to compare suppliers objectively.
The checklist helps Project Managers assess:
-
Scope clarity
-
Technical capability
-
Project methodology
-
Testing strategy
-
Documentation standards
-
Risk management approach
-
Support capability
-
Commercial value
​
Using a consistent scoring approach makes it easier to compare proposals and identify potential project risks before work begins.
Signs an Automation Proposal May Contain Hidden Risks
Be cautious if a proposal contains:
​
-
Very little technical detail
-
No site survey evidence
-
No testing plan
-
Unclear deliverables
-
Missing documentation requirements
-
Unrealistically short timescales
-
Significantly lower pricing than competitors
-
No mention of risk management
​
These often indicate hidden project risks.
