Optimizing Manufacturing Performance

Manufacturing processes are often plagued by inefficiency.   Here's why:   Manufacturers cling to old batch habits. ___   Batch Production is a traditional manufacturing method where identical or similar items are produced in batches before moving on to the next step.   Some manufacturers argue that large batches balance workloads and minimize changeovers.   But data often shows otherwise.   Overlong production runs cause overproduction. Operators lose focus working on large batches while equipment drifts out of standards between changeovers.   Main drawbacks:   -Piles of WIP inventory waiting for the next step -Defects hide among the batches -Inefficient space management -Uneven workflow -Long lead times   Those lead to:   -Some stations being overloaded, others waiting -Low responsiveness to customer demand -More scrap and rework -Higher carrying costs -Facility costs up   Switching to One-Piece Flow can bring relief.    Workstations are arranged so that products can flow one at a time through each process step, making changeovers quick and routine.   Main advantages:   +High customer responsiveness +Minimal work-in-process inventory +Quality issues are detected immediately +Reduced wasted space and material handling +Easy to level load production to match takt time   The selection between batch processing and one-piece flow can significantly impact quality, productivity, and lead time in a manufacturing process.   P.S. Some case studies show improvements in labour productivity of 50% or more. Lead times can drop by 80%. And quality can approach Six Sigma.

CAPEX estimation for low maturity technology projects is challenging, particularly when we talk about new equipment. Yet, we still need to be able to get fairly accurate figures to justify the viability of the technology and secure funding for its development. How to do it? Here is what we usually do for hydrogen and carbon capture projects. 1. Define the Project Scope Start by clearly outlining all project boundary, objectives and deliverables. Identify every cost elements required for full scale implementation, from engineering and design to construction and commissioning, while distinguishing between one-off investments and those that can be standardised. 2. Develop the first-of-a-kind CAPEX Estimate • Detailed Bottom-Up Analysis: Break down the project into its individual components, accounting for bespoke engineering, pilot testing, specialized installations, and comprehensive project management. • Risk and Contingency: Due to the innovative nature and inherent uncertainties of FOAK projects, incorporate generous contingencies to cover design modifications, unforeseen challenges, and regulatory uncertainties. • Documentation: Maintain thorough records of assumptions and decisions made during this phase, as these will inform future projects. 3. Estimate to the nth-of-a-kind estimate with learning curves Leverage the insights from the FOAK phase to isolate repeatable cost elements. With each subsequent build, learning curves drive efficiencies: • Standardize Processes: As you replicate the project, streamline designs and processes. • Realize Efficiency Gains: Experience leads to better vendor relationships and operational refinements, translating into significant cost reductions for repeatable components. • Adjust Estimates: Update your cost models to reflect these improvements, using your own or reported learning curves, ensuring more accurate and lower capital expenditure projections for future projects. 4. Implement Continuous Improvement Regularly revisit and refine both FOAK and NOAK estimates. As more operational data becomes available, adjust your assumptions and conduct sensitivity analyses to maintain a robust, realistic capex projection. How do you estimate CAPEX for your technology? #Innovation #research #hydrogen #carboncapture #science #scientist #chemicalengineering

Operational bottlenecks are often mistaken for minor distractions. In textiles, challenges such as machine downtime, dye-house delays, working capital spikes, or capacity mismatches between spinning and weaving are not just inconveniences. They are critical leverage points for value creation and significant professional impact. Many leaders focus on optimising every area. However, sustainable throughput comes from identifying and rigorously managing the single constraint that governs the entire system. We apply the Theory of Constraints (TOC) at RSWM to convert operational friction into performance gains. TOC shows that local efficiency can be misleading. Keeping every department busy often creates excess work-in-progress, disrupting flow, increasing costs, and delaying deliveries. Instead, we follow a disciplined process: -First, identify what sets the pace of the value chain. This may include machinery misaligned with current market needs or process challenges like low Right First Time (RFT) rates in the dye house that reduce effective capacity. -Second, exploit the constraint by precise scheduling, strengthening discipline, and improving efficiency to extract more output without immediate capital deployment. -Third, align the rest of the organisation to the bottleneck’s pace to ensure smooth material flow across departments. Fourth, elevate the constraint through capital investment or process redesign, addressing capacity mismatches or refining product lines. -Finally, repeat the cycle, since the constraint shifts as performance improves. This approach has delivered tangible results at RSWM. Addressing dye-house bottlenecks increased throughput, reduced working capital requirements, and improved EBITDA. However, constraints change over time. Market shifts, such as China’s shift from a major yarn importer to an exporter, or recent U.S. tariffs affecting demand, can pose new challenges. In response, we adapt by exploring alternative markets, leveraging domestic opportunities, or innovating products to sustain growth. Our goal is to eliminate internal friction so operational excellence drives expansion. When the market is the only constraint, the organisation is positioned to thrive. #TheoryOfConstraints #OperationalExcellence #Textiles #Leadership #RSWM

Clearly defining a company's final product before choosing the type of medical cannabis to produce is essential. This strategic step influences numerous aspects of the business, from production to compliance, and ultimately determines success in the competitive medical cannabis sector. 1. Product Definition and Market Positioning: A thorough understanding of the final product aids in carving out a niche in the market. Various forms, such as tinctures, oils, edibles, or dried flowers, cater to different patient needs and medical conditions. Defining the product early on ensures that the production process aligns with the intended therapeutic use and branding strategy. 2. Strain Selection and Production Process: The choice of cannabis strain directly impacts the final product's properties. For example, high-CBD strains may be more suitable for oils and tinctures intended to treat anxiety or epilepsy, while high-THC strains could be used for pain management. The cultivation, harvesting, and extraction methods will also vary depending on the end product, so a clear vision is key to streamlining these operations. 3. Compliance and Certification Requirements: The regulatory landscape for medical cannabis is strict and varies greatly by jurisdiction. Defining the final product informs the level of compliance required. Different certifications may be necessary for products consumed orally versus those applied topically. Additionally, GMP (Good Manufacturing Practices) compliance can be tailored to the needs of the production facility. 4. Testing and Quality Assurance: Different products require specific testing protocols to ensure safety and efficacy. For instance, products intended for inhalation need different tests compared to those meant for oral ingestion. Setting a clear product goal allows the company to establish accurate testing protocols and invest in the appropriate lab equipment. 5. Supply Chain Management: A well-defined final product helps align the supply chain. Whether sourcing particular cannabis strains or investing in specialised extraction machinery, having a clear end goal ensures that upstream and downstream processes are efficient and cost-effective. 6. Patient Safety and Efficacy: Ultimately, patient safety is a priority in medical cannabis. By defining the final product early on, a company can develop accurate dosage guidelines, ensure consistent potency, and avoid contamination risks. This precision helps maintain patient trust and reduces the likelihood of product recalls or adverse events. Defining the final product before production is pivotal. It ensures a more efficient, compliant, and patient-focused approach, supporting the company's market position while upholding the industry's highest standards for safety and efficacy. #medicalcannabis #cannabisindustry #strategy Picture ©Carl Haffner 2024

𝗛𝘂𝗺𝗮𝗻-𝗖𝗲𝗻𝘁𝗲𝗿𝗲𝗱 𝗗𝗲𝘀𝗶𝗴𝗻 𝗶𝗻 𝗔𝗰𝘁𝗶𝗼𝗻 Design goes beyond aesthetics—it's about functionality and user experience. It’s not just about making products look good; it's about how they work seamlessly in our daily lives. From the intuitive interface of the iPhone to the ergonomic design of the MacBook, we all know how Apple exemplifies Steve Jobs' belief that design is not just appearance. Great design is how it works. Our world is making a conscious shift towards human-centered design, an approach where the user is at the heart of the design process. Here’s a great case study that shows how empathy is at the core of design thinking. This approach ensures that when creating an application, product, or service, you prioritize the end-users' needs and perspectives from the very beginning of the ideation process. A children's toothbrush that remains popular today was developed through a collaboration between Oral-B and the global design firm IDEO in the mid-nineties. Instead of merely replicating existing products—a scaled-down version of an adult toothbrush—IDEO took a more insightful approach by observing children in the act of brushing their teeth. The observation revealed a significant challenge: children struggled to grip the slim toothbrush handles designed for adults due to their limited motor skills. Recognizing this, IDEO's team innovated a toothbrush with a larger, more ergonomic grip that was easier for children to hold. Every toothbrush company worldwide now produces similar designs.  A modern essential that has become almost a generational staple is the Dyson vacuum cleaner. Unlike traditional vacuums, which were often stashed away in closets due to their long, tangled cords, Dyson's sleek, cordless designs are meant to be prominently displayed and proudly showcased, not hidden away – another design win! The same goes for the Dyson hair dryer. The Dyson engineering team attended beauty school to better understand how hair dryers are used. The result was the Dyson Supersonic – a hairdryer with the tiniest motor and the Heat Shield Technology. As you can see, human-centered design is a creative approach to business problem solving. It leverages the designer's toolkit to seamlessly integrate people's needs, technological opportunities, and business imperatives.  Picture Credit: Chapter247      

Cost Estimating 🔹 What is Cost Estimating? Predicting project cost from scope + drawings + specs + market data. Used for: Tendering | Budgeting | Cost Control. Golden rule: realistic, defendable, measurable + market-based. 🔹 Levels of Accuracy: Conceptual (-25%/+40%) – Feasibility Preliminary (-15%/+20%) – Budget approval Detailed (-5%/+10%) – Tender/BOQ Control (based on actual BOQ/contracts) – Payments 🔹 Components of an Estimate: 1. Direct costs (labour, materials, plant) 2. Indirect costs (site + head office overheads) 3. Profit & Risk (margin + contingencies) 🔹 Step-by-Step Process: 1. Understand the scope 2. Quantity Take-Off (QTO) 3. Build unit rates  Unit Rate = Materials + Labour + Plant + OH + Profit 4. Add preliminaries 5. Include risk/contingencies (5–10%) 6. Review & benchmark 🔹 Quick Example: Blockwork 200 m² → 109 SAR/m² → Total = 21,800 SAR 🔹 Common Junior Mistakes: ❌ Ignoring wastage ❌ Overlooking site conditions ❌ Using “market rates” with no breakdown ❌ Forgetting preliminaries ❌ Copy-pasting old rates 🔹 Pro Tips: ✅ Keep a rate build-up sheet ✅ Build your own rate database ✅ Cross-check against cost/m² benchmarks ✅ Never submit without risk allowance ✅ Accuracy matters more than being the cheapest #QuantitySurveying #CostEstimating #BOQ

Design thinking, for me, goes beyond long-term business sustainability. At its core, it is about redesigning experiences, and I believe safety must be at the heart of that redesign.     And that can happen when empathy leads.     Often, efficiency and safety can become trade-offs. But through my years in the manufacturing space, I’ve learned that when experiences are thoughtfully designed, they reinforce each other.     Fewer failures, risks, and downstream costs.    Ultimately, what matters the most is not what we build, but how safely people can interact with it.    When the approach is founded on safety and it is treated as a design principle rather than a constraint, efficiency and cost-effectiveness follow naturally.    When we get this right, safety stops being a checklist and becomes an outcome of good design.     Redesign the experience well, and safety follows.

Product design isn't just about making things look pretty – it's about solving real problems for real people. And the story of Fiskars' iconic orange scissors is a perfect example of that. Before 1967, using scissors was a painful experience. The metal handles were uncomfortable to grip and put a lot of strain on your hands. But then industrial designer Olof Bäckström came along and decided to approach scissors from a completely different angle – putting the user first. He used leftover plastic from another project to create scissors with handles that were molded to fit the natural curves of the human hand. He ended up creating a pair of scissors that was incredibly comfortable to use and made cutting effortless. No more hand fatigue or frustration! Bäckström's user-centric design was a game-changer. People immediately noticed the difference in comfort and ease of use. And the proof is in the numbers – over 1 billion pairs of these scissors have been sold worldwide! What I love about this story is that Bäckström didn't set out to create a trendy or aesthetically pleasing product. He just focused on truly understanding the users' pain points and finding a solution that would make their lives better. And that's what great product design is all about. As product builders, we can all learn a lot from this example. It's a reminder to always keep the user at the heart of what we do and to strive for designs that genuinely improve people's experiences – even with something as simple as a pair of scissors! #productdesign #usercentricity

3 PCB Layout Tricks That Instantly Improve Manufacturability I've reviewed many PCB designs and keep seeing the same manufacturability issues that put projects at risk and increase costs. Here are 3 simple DFM-specific layout tricks you can implement TODAY that will dramatically improve your board's manufacturability (this one of many things that job descriptions mean when they refer to 'design for yield' or 'DFx' in a PCB design role): 1. The "Teardrop" Technique for Via Reliability Ever had a PCB manufacturer call you about possible breakout issues? Without teardrops, even having enough annular ring on your copper pads might not be enough to avoid breakout. Also, without tear drops, mechanical stress can cause the copper connection between a via and trace to fracture, especially with fine traces (below 6 mils). The simple fix: Add teardrops to via-to-trace connections on high-current paths and mechanically stressed areas - or just in general. Looks nicer, too. This increases the copper area at the junction by 30-40%, improving durability during thermal cycling and reducing drill breakout risk. PRO TIP: Most PCB software has this built-in, but few engineers consistently apply it on newer boards. 2. The "Edge Spacing" Rule for Better Yields Many new designers place components too close to the board edge, creating problems during depanelization. But they of course wouldn't know. It's inside standards and not necessarily an obvious thing to know or guess. The simple fix: Create an "Edge Spacing" design rule: - Components: Minimum 2mm from board edge - Vias: Minimum 1mm from board edge - Traces: 0.5mm from board edge (1mm for power) This prevents damage during board separation and reduces manufacturing costs. PRO TIP: Set this as a permanent design rule in your template for all future boards. 3. The "Soldermask Web" for Fine-Pitch Components With fine-pitch components (0.5mm pitch or less), standard soldermask configurations can bridge between pads. The simple fix: Implement a "soldermask web" rule for minimum soldermask web widths between pads. When soldermask opening is too large, the web becomes too thin, creating solder mask slivers and solder bridges. PRO TIP: Many manufacturers handle soldermask expansion automatically so your expansion can usually be 0 or none. Follow their specifications when available. Otherwise, for components with 0.5mm pitch or less, ensure your soldermask web is at least 0.1mm wide. None of these techniques require fancy software or advanced knowledge. They're simple rules you can implement in ANY PCB design tool for DFx. Note this: A perfect circuit design that can't be reliably manufactured is ultimately useless. #PCBDesign #DFM #HardwareEngineering #ManufacturabilityTips
