Task observations are an excellent leading indicator for construction health and safety performance. This application is used to record, categorise and submit observations of safe and unsafe behaviours on specific Worley construction sites. Access is restricted to Worley, their customers and subcontractors. An “observation card” is filled out and submitted following the observation of a construction or maintenance activity. In most circumstances a conversation with the observed individuals should also occur. The card data is then collated, analysed and presented in a separate application. This application is for the exclusive use of Worley, their customers and their contractors.

Verdict
The clearest difference is update cadence: OQSHA at every 2 weeks against HSE Observer's every 20 months. HSE Observer's advantage is iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.
