## Why a checklist matters
Industrial IoT (IIoT) projects in Southeast Asia often involve multiple stakeholders—OT/engineering teams, IT/security, procurement, and sometimes system integrators. A structured procurement checklist helps you compare vendors consistently, reduce integration surprises, and ensure the solution fits your plant environment and compliance expectations.

This guide is educational and focuses on what to verify when sourcing an **industrial IoT** offering.

## 1) Scope and use cases (before you compare prices)
Start by writing down the exact outcomes you need, such as:
- Asset monitoring (uptime, condition, alarms)
- Production visibility (line status, throughput, downtime)
- Energy monitoring (consumption, peaks, anomalies)
- Predictive maintenance workflows (if applicable)

Procurement should confirm:
- Which assets/lines are in scope for the first phase
- Expected data frequency (e.g., event-based vs. periodic)
- Whether you need edge processing or only data collection

---

## 2) Architecture fit: edge, connectivity, and data flow
For IIoT, the architecture determines both cost and risk. Verify:
- **Edge vs. cloud**: where data is processed and where decisions are made
- **Connectivity**: how devices communicate (wired/wireless) and how they reach your network
- **Data pipeline**: how data is stored, transformed, and accessed by applications

Procurement should request clear diagrams showing:
- Device-to-edge-to-platform data flow
- Network boundaries (what crosses from OT to IT)

---

## 3) Compatibility with your existing control environment
Even when a solution is “industrial,” compatibility is often the deciding factor. Confirm:
- How the solution connects to your PLCs/SCADA environment (e.g., via supported protocols)
- Whether it supports the specific device types you already use
- How tags/variables are mapped and maintained over time

Ask vendors to provide:
- A compatibility matrix (supported controllers, gateways, and software versions)
- Migration approach if you plan to expand later

---

## 4) Security and access control
Industrial buyers should treat security as a procurement requirement, not an afterthought. Verify:
- Authentication and role-based access for users and services
- Encryption in transit and at rest (where applicable)
- Audit logs and administrative controls
- How updates/patching are handled for edge components

Procurement should also confirm whether the vendor supports:
- Segmented network deployment (OT/IT separation)
- Secure remote access (if remote support is needed)

---

## 5) Data governance and operational reliability
IIoT value depends on data quality and uptime. Check:
- Data retention policies and export options
- Handling of intermittent connectivity (buffering, retry behavior)
- Time synchronization approach (important for event correlation)
- Backups and disaster recovery expectations (for platform components)

---

## 6) Performance requirements (define them up front)
Avoid vague requirements. Define measurable targets such as:
- Maximum number of devices/points per gateway or platform instance
- Expected latency from event to dashboard/alert
- Throughput for your highest-load line

Procurement should request performance documentation or test methodology from vendors.

---

## 7) Installation, commissioning, and training
Total cost of ownership includes deployment effort. Confirm:
- Installation requirements (power, mounting, cabling, environmental conditions)
- Commissioning steps and expected timeline
- Training deliverables (who is trained, what modules, and how many sessions)

---

## 8) Warranty, support, and service levels
Before purchase, clarify:
- Warranty duration and what it covers
- Support channels (email/portal/phone) and response-time expectations
- Replacement/repair process for hardware components
- Software update policy during the warranty/support period

---

## 9) Documentation and compliance evidence
Procurement should ensure you receive:
- User manuals, installation guides, and technical documentation
- Any relevant compliance documentation the vendor can provide
- Licensing terms for software components (if any)

---

## 10) Commercial terms that protect your project
Finally, align commercial terms with operational needs:
- Lead times and delivery schedule
- Acceptance criteria for commissioning
- Scope boundaries (what is included vs. excluded)
- Change control process for expansion phases

---

## Closing note
A strong IIoT procurement process is less about finding the “cheapest device” and more about verifying architecture fit, compatibility, security, performance, and support.
