Process & Workflow Optimization for Manufacturers
Expert analysis and implementation that eliminates bottlenecks and maximizes throughput — without adding machines or headcount.
Unlock Hidden Capacity on Your Shop Floor
Process optimization in manufacturing is the systematic analysis and redesign of production workflows to eliminate waste, reduce cycle times, and increase output — without adding machines or headcount. It targets the root causes of lost throughput: imbalanced work cells, excessive work-in-process inventory, unpredictable bottlenecks, and scheduling chaos in high-mix environments.
The Streamline Group walks your production floor, maps your value streams, identifies the true constraints limiting output, and implements practical changes your team can sustain. We apply Theory of Constraints and lean manufacturing principles adapted to the realities of CNC job shops and OEM production — not textbook frameworks that ignore your part mix, your people, and your daily schedule pressures.
According to IndustryWeek, manufacturers implementing systematic process improvement see an average 15–25% increase in throughput from existing equipment. That is capacity you already own but are not capturing — and recovering it costs a fraction of purchasing new machines.

Common Shop Floor Problems We Solve
These issues drain throughput every shift. Most shops have learned to work around them instead of eliminating them.
Shifting Bottlenecks
The constraint moves between machines unpredictably, making it impossible to plan capacity or prioritize jobs effectively. One week it is the lathe cell; next week it is deburring.
Excessive WIP Inventory
Partially completed parts clog the floor, consume valuable space, obscure true demand signals, and extend lead times by days or weeks beyond actual machining time.
Operator Wait States
Operators stand idle waiting on upstream processes, material, tooling, or programs. Every minute of operator wait time at a bottleneck resource is throughput lost permanently.
Inefficient Part Routing
Parts travel unnecessary distances across the shop, passing through extra handling steps and queue positions that add zero value but extend cycle times and increase damage risk.
Tribal Knowledge Dependencies
Critical process knowledge lives in one or two operators' heads. When they are absent, quality drops, cycle times increase, and the shop scrambles to maintain output levels.
Scheduling Chaos
High-mix, low-volume environments create constant fire drills. Jobs get expedited, sequences change mid-shift, and on-time delivery suffers because the system has no stable rhythm.
Our Process: From Observation to Sustained Results
Every engagement follows a proven six-step methodology that starts with observation and ends with your team owning the improvements.
Shop Floor Walkthrough
We spend 1–2 full days on your production floor observing real operations. We watch how parts move, where queues form, how operators interact with machines, and where time disappears between value-adding steps. No conference rooms, no slide decks — just direct observation of your actual production reality.
Data Collection & Value Stream Mapping
We measure actual cycle times, setup times, queue times, and transport times for your key part families. This data feeds a value stream map that reveals where time and capacity are being consumed — and how much of that consumption adds value versus waste. We use takt time calculations to quantify the gap between current output and customer demand.
Constraint Identification
The real bottleneck is often not where people think it is. A machine running at full capacity is not necessarily the constraint — the constraint is whatever limits total system throughput. We apply Theory of Constraints analysis to pinpoint the true limiting resource, then quantify the throughput impact of subordinating the entire system to that constraint.
Solution Design
We design practical, implementable changes tailored to your specific equipment, workforce, and part mix. Solutions may include cell layout reconfiguration, workflow resequencing, batch size adjustments, setup procedure standardization, or scheduling rule changes. Every recommendation comes with projected throughput impact and implementation effort.
Implementation
We work alongside your operators and supervisors to implement changes on the floor. This is not a handoff — we are there during the transition, troubleshooting in real time, adjusting as production realities require, and ensuring changes deliver the expected results before moving to the next improvement.
Training & Handoff
Improvements only last if your team understands and owns them. We document new procedures, train operators and supervisors on the rationale behind each change, and establish simple metrics your team can monitor to sustain gains. The goal: your team can build on these improvements independently long after we leave.
Results You Can Expect
Typical outcomes from a process optimization engagement, based on our experience with CNC job shops and OEM production environments.
| Metric | Before | After (Typical) |
|---|---|---|
| Throughput | Baseline | +15–25% increase |
| WIP Inventory | Excessive, floor congested | 30–50% reduction |
| Lead Time | Variable, hard to predict | 20–40% shorter |
| On-Time Delivery | Inconsistent | 90%+ sustained |
| Setup Time | Long, highly variable | 40–70% reduction |
Results vary by facility. Figures represent typical ranges observed across multiple manufacturing engagements. Setup time reductions are achieved using SMED-based methods integrated into the broader process optimization.

Why These Numbers Matter
A 20% throughput increase on a shop running $3 million in annual revenue represents $600,000 in additional capacity — from the same machines and the same people. That is not theoretical. It is the mathematical result of removing waste from your production flow.
The National Association of Manufacturers estimates that U.S. manufacturers lose 20% of productive capacity to inefficiency. Our engagements consistently recover a significant portion of that lost capacity within the first 4–8 weeks.
Frequently Asked Questions
Most process optimization projects run 4–8 weeks from initial walkthrough to training handoff. A focused single-cell optimization may complete in 3–4 weeks. A comprehensive multi-cell engagement involving value stream mapping, constraint analysis, and workflow redesign across several production areas typically takes 6–8 weeks. We define the scope and timeline during the initial walkthrough so there are no surprises.
Minimal disruption is a core design principle in our methodology. The observation and data collection phases happen during normal production. Implementation changes are staged during natural breaks in the schedule — shift changes, weekends, or between job runs. We never shut down a production cell without a plan to bring it back online faster and more efficient. Your delivery commitments remain the priority throughout.
What looks like a capacity problem is often a flow problem. When WIP piles up, lead times stretch, and machines appear maxed out, the instinct is to buy another machine. But in many shops, the existing equipment is capable of 15–25% more output once workflow imbalances, excessive setups, and scheduling inefficiencies are resolved. We verify this with data before recommending any capital investment. If you genuinely need more capacity, our machine tool evaluation service ensures you buy the right equipment for your actual constraint.
We integrate with your existing systems, whether that is a full ERP platform, a standalone MES, or spreadsheets and whiteboards. Process optimization improvements need to be reflected in whatever scheduling and tracking tools your team actually uses. We help configure routing updates, standard times, and scheduling parameters so your system reflects the new reality — not the old one.
