While policies and procedures describe how work should be done, they do not always reflect how tasks are carried out in reality. A true assessment of performance requires looking at day-to-day operations to understand what actually happens across the organisation.\n\nA key part of this approach involves structured interviews with staff at different levels and roles. These conversations help auditors understand how people carry out their responsibilities, what tools they use, and how decisions are made. Interviews also help identify whether staff understand the processes they are expected to follow and whether informal workarounds have developed.\n\nObservation of live operational activity is another important method. By watching tasks as they are performed, auditors can see how processes function under normal working conditions. This often reveals gaps that are not documented, such as skipped steps, inconsistent application of controls, or reliance on informal knowledge rather than formal procedures.\n\nEvidence review is also critical. Organisations generate a wide range of records such as logs, reports, system outputs and screenshots. Reviewing this evidence across teams and functions helps confirm whether processes are consistently applied and whether controls are operating effectively over time, not just during audit preparation.\n\nBecause it is not practical to review every record or transaction, sampling techniques are used. Sampling involves selecting representative examples that reflect how a process operates across different teams, systems or locations. This allows auditors to assess control effectiveness efficiently while still gaining confidence that results reflect overall performance.\n\nBy combining interviews, observation, evidence review and sampling, auditors are able to build a balanced and reliable view of how processes actually work in practice. Each method complements the others and helps reduce bias, ensuring findings are based on evidence rather than assumptions or opinions.\n\nThis approach also helps identify where processes are working well and where improvements are needed. It highlights strengths as well as weaknesses, making the audit more valuable to the organisation. Instead of focusing only on compliance, it provides insight into real operational effectiveness.\n\nUltimately, understanding how processes work in practice ensures that audits are meaningful and actionable. It helps organisations move beyond documentation and gain a clear view of operational reality. This leads to better decision-making, stronger controls, and continuous improvement of the management system over time.","about":[{"@type":"Thing","name":"ISO 27001"},{"@type":"Thing","name":"Internal Audit"},{"@type":"Thing","name":"Business Process Management"}],"mentions":[{"@type":"Organization","name":"Parkinson Howe","url":"https:\/\/parkinsonhowe.co.uk\/"}]},{"@context":"https:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"2026","item":"https:\/\/parkinsonhowe.co.uk\/2026\/#breadcrumbitem"},{"@type":"ListItem","position":2,"name":"05","item":"https:\/\/parkinsonhowe.co.uk\/2026\/\/05\/#breadcrumbitem"},{"@type":"ListItem","position":3,"name":"14","item":"https:\/\/parkinsonhowe.co.uk\/2026\/\/05\/\/14\/#breadcrumbitem"},{"@type":"ListItem","position":4,"name":"Understanding how processes work in practice","item":"https:\/\/parkinsonhowe.co.uk\/2026\/05\/14\/understanding-how-processes-work-in-practice\/#breadcrumbitem"}]}]
