Two models are traditionally set against each other: the <strong>push flow<\/strong> and the <strong>pull flow<\/strong>. Understanding their differences, advantages and limitations is essential to optimise the <strong>supply chain<\/strong> et renforcer l&#8217; <strong>operational excellence<\/strong>\u00a0of your company.<\/p>\n<p>It is important to support manufacturers in choosing and implementing the flow model best suited to their strategy, while integrating the principles of <strong>lean manufacturing<\/strong> and on the <strong>Operational performance<\/strong>.<\/p>\n<h4>What is a push flow?<\/h4>\n<p>The <strong>push flow<\/strong> (or <em>push system<\/em>) is based on a <strong>forward planning<\/strong>. Production is launched upstream on the basis of a <strong>demand forecasting<\/strong>, often based on historical data or market trends.<\/p>\n<p><strong>Example<\/strong> : A factory produces 10 000 units of a component in January, anticipating demand in March.<\/p>\n<p><strong>Advantages<\/strong> :<\/p>\n<ul>\n<li>Better use of production capacity (high utilisation rate).<\/li>\n<li>Lower unit costs thanks to large batches.<\/li>\n<li>Suited to stable products with highly predictable demand.<\/li>\n<\/ul>\n<p><strong>Drawbacks<\/strong> :<\/p>\n<ul>\n<li>Risk of <strong>overproduction<\/strong> (one of the 7 wastes of Lean).<\/li>\n<li>Accumulation of <strong>intermediate stocks<\/strong>.<\/li>\n<li>Less responsiveness to changes in demand.<\/li>\n<\/ul>\n<p>This model is common in highly seasonal industries or in environments where production is long and costly to launch.<\/p>\n<h4>And the pull flow?<\/h4>\n<p>The <strong>pull flow<\/strong> (<em>pull system<\/em>), inspired by the <strong>Toyota system<\/strong>, operates on the principle of <strong>just-in-time<\/strong>. Production is triggered by an <strong>actual order<\/strong>, not by a forecast.<\/p>\n<p><strong>Example<\/strong> : A part is only manufactured when a customer places an order or a downstream workstation needs it.<\/p>\n<p><strong>Advantages<\/strong> :<\/p>\n<ul>\n<li>Drastic reduction in <strong>stock levels<\/strong> and <strong>tied-up capital<\/strong>.<\/li>\n<li>Less waste (quality, obsolescence).<\/li>\n<li>Plus de <strong>flexibility<\/strong> and <strong>responsiveness<\/strong>.<\/li>\n<\/ul>\n<p><strong>Drawbacks<\/strong> :<\/p>\n<ul>\n<li>Requires <strong>fine-tuned planning<\/strong> and <strong>close collaboration<\/strong> with suppliers.<\/li>\n<li>Less suited to unexpected demand peaks.<\/li>\n<li>Depends on a robust information system (ERP, MES).<\/li>\n<\/ul>\n<p>The <strong>Kanban<\/strong> is one of the most emblematic tools of the pull system: cards or visual signals indicate when to replenish a workstation.<\/p>\n<h4>The ideal synergy: a hybrid system<\/h4>\n<p>In practice, high-performing companies often combine both approaches:<\/p>\n<ul>\n<li><strong>Flux pouss\u00e9<\/strong> upstream, for raw materials or standardised components.<\/li>\n<li><strong>Flux tir\u00e9<\/strong> downstream, for final assembly or customisation.<\/li>\n<\/ul>\n<p>This is what is known as a <strong>heijunka system<\/strong> (production levelling), which makes it possible to <strong>stabilise flows<\/strong> while remaining responsive.<\/p>\n<h4>The bottleneck: enemy no. 1 of flow<\/h4>\n<p>Whichever model is chosen, the <strong>bottleneck<\/strong> remains a major obstacle to flow. It is a process step whose capacity is lower than demand, thereby limiting overall throughput.<\/p>\n<p><strong>Example<\/strong> : A machine capable of producing 100 parts\/hour while the line can process 150.<\/p>\n<p>To identify a bottleneck, use:<\/p>\n<ul>\n<li>The<strong>capacity analysis<\/strong> of each workstation.<\/li>\n<li>The <strong>bottleneck calculation<\/strong> (cycle time \/ maximum cycle time).<\/li>\n<li>numerous <strong>dashboards <a href=\"https:\/\/fr.wikipedia.org\/wiki\/Indicateur_cl%C3%A9_de_performance\" target=\"_blank\" rel=\"noopener\">KPI<\/a>s<\/strong> (OEE, throughput rate, downtime).<\/li>\n<\/ul>\n<p>Use the <strong>Value stream mapping (VSM)<\/strong> to visualise flows, detect bottlenecks and propose solutions to optimise your operational excellence.<\/p>\n<h4>Case study: transition from a push system to a partial pull system<\/h4>\n<p>An electrical equipment company was suffering delivery delays despite high stock levels. Our audit revealed:<\/p>\n<ul>\n<li>An <strong>overproduction<\/strong> of 30 % on certain components.<\/li>\n<li>An <strong>bottleneck<\/strong> on the final test line.<\/li>\n<li>An <strong>supply chain<\/strong> with poor responsiveness.<\/li>\n<\/ul>\n<p>We implemented:<\/p>\n<ol start=\"1\">\n<li>An <strong>Kanban system<\/strong> between assembly and stock.<\/li>\n<li>An <strong>project planning<\/strong> redesigned with smaller batches.<\/li>\n<li>An <strong>automation of the logistics flow<\/strong> thanks to an MES.<\/li>\n<\/ol>\n<p>Result: stock reduced by 45 %, OEE improved by 22 %, and delivery times cut by 30 %.<\/p>\n<h4>Link with the industrialisation of a product<\/h4>\n<p>The design of a <strong>new product<\/strong> is the key moment to integrate the right flows. The<strong>industrialisation of a product<\/strong> must include:<\/p>\n<ul>\n<li>The definition of the <strong>industrial process<\/strong>.<\/li>\n<li>The choice between <strong>push or pull system<\/strong> depending on the strategy.<\/li>\n<li>The drafting of a <strong>technical specification document<\/strong> that is precise.<\/li>\n<li>The <strong>validation industrielle<\/strong> of the process.<\/li>\n<\/ul>\n<p>An <strong>manufacturing file<\/strong> , when well structured, makes it possible to standardise production from the outset, avoiding costly corrections along the way.<\/p>\n<p><em>Discover our article \u00ab <a href=\"https:\/\/sxe-consulting.com\/en\/complete-guide-to-writing-technical-specifications\/\">How to write an effective technical specification document?<\/a> \u00bb.<\/em><\/p>\n<h4>Conclusion<\/h4>\n<p>The choice between <strong>push flow<\/strong> and <strong>pull flow<\/strong> is not a question of fashion, but of <strong>industrial strategy<\/strong>.
