Have you identified a complex problem within your organisation, such as a production breakdown, yet struggle to grasp its root causes? Quintilian questioning, or the QQOQCCP method, provides a structured framework for analysing any situation rigorously, tracing issues back to their root causes without hasty judgement. Discover how its 7 key questions \u2013 Who, What, Where, When, How, How much, Why \u2013 turn a chaos of information into a targeted action plan<\/strong>, combining exhaustiveness and objectivity. An essential method for professionals in industrial performance or project management, capable of quantifying the impact of a problem or of defining responsibilities through an approach proven since Antiquity.<\/p>\n

    What is Quintilian questioning, or QQOQCCP?<\/h2>\n

    A Luxembourg factory suddenly suffers a 15 % drop in productivity. The technical teams observe irregular malfunctions affecting several machines, leading to costly delays estimated at 800 000 euros<\/strong> in two weeks. How can the causes be identified without getting lost in the complexity of the problem?<\/p>\n

    Quintilian questioning, also called QQOQCCP or the Quintilian hexameter, offers a structured solution. This ancient method, dating back to the 1st century, breaks a complex situation down into seven key questions \u2014 Who? What? Where? When? How? How much? Why? \u2014 in order to gather objective data. Its principle? Exploring every angle of a problem, avoiding hasty interpretations and guiding towards informed decisions<\/strong>.<\/p>\n

    Traditionally associated with the Roman rhetorician Marcus Fabius Quintilianus, this approach draws on ancient rhetorical techniques. Although its origin is sometimes linked to Aristotle or Cicero, its modern adaptation makes it a key tool in industrial project management. In practice, it helps to pinpoint specific causes<\/strong> : equipment failure, incorrect settings, or a logistics problem, as in the case of the Luxembourg factory.<\/p>\n

    Used by industrial performance experts, this method applies to solving technical problems, to digital transformation and to supply chain optimisation. It turns confusion into targeted actions, as illustrated by a case in which critical deliveries were secured within 10 days. In the following sections, discover how it is applied in practice to diagnose malfunctions or to structure industrial strategies.<\/p>\n

    The 7 fundamental questions of the QQOQCCP method<\/h2>\n

    The QQOQCCP method rests on seven questions targeting every aspect of a problem, for an exhaustive analysis<\/strong>. Derived from Quintilian questioning, this framework applies to solving industrial problems, to project management and to process optimisation. Its standardised approach is particularly useful in an international context, notably for demanding sectors such as logistics or digital transformation.<\/p>\n

    Question<\/th>\nMain objective<\/th>\nExamples of sub-questions<\/th>\n<\/tr>\n
    Who?<\/td>\nDefine the people involved.<\/td>\nWho are the stakeholders? Who is responsible? Who is the target\/affected party?<\/td>\n<\/tr>\n
    What?<\/td>\nDescribe the nature of the problem.<\/td>\nWhat is it about? What are the symptoms? Which objective is affected?<\/td>\n<\/tr>\n
    Where?<\/td>\nLocate the problem.<\/td>\nIn which physical or virtual location? On which equipment?<\/td>\n<\/tr>\n
    When?<\/td>\nPlace the problem in time.<\/td>\nOn what date? For how long? What is the frequency?<\/td>\n<\/tr>\n
    How?<\/td>\nUnderstand the process and the means.<\/td>\nHow does the problem manifest itself? Which procedures are followed?<\/td>\n<\/tr>\n
    How much?<\/td>\nQuantify the problem.<\/td>\nWhat is the cost? How many people are affected?<\/td>\n<\/tr>\n
    Why?<\/td>\nIdentify the root causes.<\/td>\nWhy did the procedure fail? What is the root cause?<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

    In a business context, these questions structure the analysis of complex situations. For example, in the case of a logistics delay, \u201cWhere?\u201d locates the bottleneck (warehouse, transport line), \u201cHow much?\u201d quantifies the losses, and \u201cHow?\u201d sets out the failing procedures. The method avoids hasty judgements by relying on objective data<\/strong>.<\/p>\n

    The distinction between \u201cWhy?\u201d (causes) and \u201cWhat for?\u201d (purpose) is essential. For an industrial project in Luxembourg, \u201cWhy?\u201d may point to an equipment defect, whereas \u201cWhat for?\u201d directs attention to a clear objective, such as improving productivity. Combined with the quantitative analysis of \u201cHow much?\u201d, this approach prioritises corrective actions and measures their effectiveness, making QQOQCCP a strategic decision-making tool.<\/p>\n

    How to move from QQOQCCP analysis to a concrete action plan?<\/h2>\n

    Turning a QQOQCCP analysis into a structured action plan is the decisive step in moving from observation to resolution<\/strong>. In an international industrial context, this method stands out as a strategic lever for Luxembourg companies specialising in industrial performance. The answers provide precise data, but exploiting them requires a rigorous methodology. Without this approach, the information remains inert, depriving the company of concrete levers to optimise its processes, its supply chain or its digital transformation.<\/p>\n

    The objective collection of answers is the first critical step. Each question must be addressed neutrally, without hasty interpretation. For example, answering \u201cWhen?\u201d means recording the exact dates on which a malfunction occurred on a production line. For a company operating in Europe and Asia, this approach aligns teams around indisputable data, eliminating disagreements caused by cultural or subjective bias. Precision is crucial: a repeated delivery delay recorded over 3 months then becomes the basis for targeted analyses<\/strong>.<\/p>\n

    Analysing the \u201cWhy\u201d question reveals hidden root causes. A recurring quality problem on a production line may be linked to poorly calibrated machine parameters (tool, method) or to a deviation from procedures. The cause-and-effect diagram<\/a> then becomes a valuable ally<\/strong> for prioritising corrective actions. For example, in a case of excess steelmaking waste, the QQOQCCP answers on operating conditions (How?) and resources used (How much?) feed directly into the \u201cMachines\u201d and \u201cMaterials\u201d branches of the diagram.<\/p>\n

    Converting the answers into an action plan follows a systematic logic<\/strong> : each answer becomes an operational lever. \u201cWho\u201d determines those responsible, such as a digital project manager or a process optimisation expert. \u201cWhat\u201d defines the precise tasks, from installing an IoT monitoring system to re-engineering a logistics flow. \u201cWhere\u201d specifies the sites concerned, whether a factory in Luxembourg or a warehouse in China. \u201cWhen\u201d sets realistic milestones, with deadlines spread over 6 months for an automation project. \u201cHow\u201d describes the exact procedures, such as applying ISO standards. \u201cHow much\u201d allocates the resources, with a detailed budget for predictive maintenance. Finally, \u201cWhy\u201d justifies the actions through measurable objectives, such as a 15 % reduction in production costs in 4 months.<\/p>\n
