A HAZOP (Hazard and Operability Study) is a systematic way of finding failure points or areas of improvement in all your business processes. The result of HAZOP will be that you have massively improved the robustness and efficiency of all your buisiness operations
HAZOPs were first used in the chemical engineering industry and more recently in the oil and gas and nuclear industries, however the methodology can be used in all business where there is a defined systematic process.
HAZOP RS is an excellent tool for scrutinising any business process no matter how many users, environments, locations or devices.
HAZOP RS facilitates multi-location (teams do not have to be in the same room or even country), multi-domain and multi-team HAZOPs that are mapped entirely to your organisation hierarchy. HAZOP RS allows you to fully quantity events, prioritise identified areas of improvement, manage follow up actions and produce concise reports. HAZOP RS functions on any device.
Starting with a process flow diagram (e.g. from a Business Systems Analysis, a business flow desktop study, flow chart or engineering blue print drawing) of a particular system/process or sub system/sub process within your business, a specific functional part is analysed. An effective HAZOP will always split the system into manageable functional parts. The specific part to be analysed is one section of the flow diagram that is designed, in its current state to achieve a certain task e.g. in generic business this may be "load online orders into the customer relationship management software" or in engineering this may be "extract 1kg of dust from column B every 90 minutes". This specific task is termed the intent. Typically, intents should have been designed in such a way as to allow for fluctuations. E.g. in the CRM example there might be different types of customer, different data entry points etc and in the dust extraction example there may be different amounts of dust, different operating temperatures or varying up and downstream requirements.
Each of these individual intents have possible fluctuations in effectiveness. E.g. what if the GUI doesn't work on the user's device, or what if the dust extraction pump fails in certain temperatures? This is exactly where a HAZOP is useful. The HAZOP team systematically looks at each possible scenario with the aim of identifying potential problems/ hazards and especially ascertaining causes and consequences - here you are looking for deviations from the intent and this is typically carried out by introducing pre-defined key words in the context of each intent/part such as "MORE (flow)", ,"LESS (power)", "INCREASE (temperature)", "DECREASE (resistance)" - you can choose your own key words that are specific to your operations and business and especially the system you are analysing, the key is to use consistency throughout.
Chairman - someone experienced in HAZOP methodology but not directly involved in the design or business flow. They are their to ensure that the HAZOP is carried out carefully and are responsible for ensuring that the discussion is effective, purposeful and leads to a definite conclusion that is adequately recorded, all problems are documented and suggestions/recommendations passed on to the relevant parties following the HAZOP.
Secretary - to accurately record discussions, problems and recommendations on behalf of the Chairman. A secretary should also have knowledge of the HAZOP process and experience of the operating industry will help so they can recognise terms and identify relevant discussion points.
Designer - someone involved heavily in the design represented in the intent diagrams.
User - someone who will be using the system dictated in the diagrams and who can give sound judgement on the effects of deviation from a user perspective.
Specialist - an individual with relevant and high level skilled technical knowledge, e.g. specific knowledge about component parts, reactions, analysis down to the last detail.
Maintainer - someone who will be involved in long term maintenance of the system or operating environment.
