Key Points
- Defines measurable commitments for system uptime, response time, and support availability.
- Establishes consequences for failing to meet agreed service levels.
- Critical when selecting SaaS vendors for safety-critical PTW systems.
- Should include data backup, recovery time, and security incident response commitments.
Definition
SLA defines expected service performance levels between provider and customer.

Key Performance Indicator (KPI)
KPIs are measurable values used to evaluate performance and efficiency.
Software as a Service (SaaS)
SaaS is a cloud-based software delivery model where users access applications via the internet without local installation. It enables scalability, remote access, and continuous updates.
Compliance
Compliance refers to adherence to laws, regulations, and internal standards. It ensures that operations meet legal and safety requirements. Non-compliance can lead to serious consequences.
Governance
Governance defines how decisions are made, responsibilities are assigned, and processes are controlled. It provides structure and accountability across operations.
Electronic Permit to Work (e-PTW)
An electronic Permit to Work system digitizes the traditional PTW process, replacing paper-based permits with a centralized software solution. It enables real-time visibility into all ongoing work, automated workflows, and consistent enforcement of safety rules. Digital systems can integrate risk assessments, approvals, isolations, and communication into one platform. In practice, e-PTW improves efficiency, reduces human error, and enables better data tracking and reporting across sites.

Audit Trail
An audit trail records all actions taken in a system, providing full traceability. It is essential for compliance and investigations.
Role-Based Access Control (RBAC)
RBAC restricts system access based on user roles and responsibilities. It ensures users only access relevant information.
Permit Validity
Defines the time period during which a permit is valid and work is allowed.
Permit Suspension
Temporary halt of work due to safety concerns or changing conditions.
Frequently Asked Questions
Why are SLAs important for PTW software?
PTW systems are safety-critical applications. Downtime can halt operations across an entire site. SLAs ensure the vendor commits to specific uptime levels, support response times, and data recovery capabilities.
What uptime should an SLA specify for safety systems?
Safety-critical systems typically require 99.9% or higher uptime. The SLA should also define planned maintenance windows, maximum allowed downtime, and offline capability if the system is unavailable.
