Sofema Online (www.sofemaonline.com) considers the role and purpose of Aviation Safety Management System (SMS) - Safety Performance Indicators (SPI) within an EASA Part 21 G Organisation.

Introduction – Key Performance Indicator (KPI)

Typically measures how well your operation is doing at achieving its maintenance goals, for example reducing downtime or costs. KPIs can be used as a benchmark to understand your organisations current position as well as to facilitate the development of Key Performance goals.

Sofema Online (SOL) www.sofemaonline.com considers the optimum organizational safety system behaviours to effectively monitor safety performance.

Introduction - ICAO identifies an SPI as a “a data-based safety parameter used for monitoring and assessing safety performance.”  By developing effective organizational SPIs, we are able to measure and manage the processes to ensure the optimum output with a focus on the precursors of potentially serious events, rather than current visible outcome.

Why to Use Safety Performance Indicators?

Considering ICAO Definition of Safety

ICAO Annex 19 defines safety as ‘the state in which risks associated with aviation activities, related to, or in direct support of the operation of aircraft, are reduced and controlled to an acceptable level’ and safety performance as ‘a service provider’s safety achievement as defined by its safety performance targets and safety performance indicators’.

Challenges to Establish Confidence in Safety Performance?

Whilst it is usual for safety metrics to focus on serious incidents and accidents it is also possible to gain a false impression regarding the overall level of safety due in part to a system with a low number of high consequence negative outcomes, means the low frequency of such outcomes may give the wrong impression that your system is safe.
