Process Optimization for Mechanical Engineering
Mechanical engineering thrives on precision and reliability. From CNC machining to final assembly, long lead times, complex BOMs, and small-batch production create unique optimization potential. Leanshift captures the data where value is created -- at the machine.
Challenges
Long and unpredictable lead times
Custom orders with varying complexity make production planning difficult and lead times hard to quote accurately.
High machine setup times
Frequent job changes on CNC machines and machining centers consume productive capacity.
Skilled labor dependency
Critical process knowledge resides with experienced operators, making standardization difficult.
Quality assurance for tight tolerances
Micron-level precision requirements mean rework is costly and scrap rates directly impact margins.
Relevant KPIs
Typical Process Example
Map the order flow
Use Value Stream Mapping to trace a typical order from quote to shipment, identifying delays and queues.
Measure machine utilization
Record cycle times and setup times on critical bottleneck machines over multiple shifts.
Analyze setup processes
SMED analysis separates internal from external setup activities on CNC machines.
Implement flow improvements
Reorganize workstations, introduce Kanban for tooling, and create visual management boards.
Coach and sustain
Weekly Gemba walks and PDCA coaching cycles ensure improvements stick and new standards hold.

Frequently Asked Questions
Does Leanshift work for single-piece and small-batch production?
Absolutely. The stopwatch and Muda analysis are designed for any batch size. In fact, small-batch environments often reveal the most waste in setup and material handling.
How do we handle different product families?
Create separate value stream maps per product family. Leanshift lets you track and compare cycle times across product types to find common improvement levers.
Can experienced operators use Leanshift without extensive training?
Yes. The app is designed for shop floor use -- start the stopwatch, categorize observations, done. Most operators are productive within 10 minutes.
Related Glossary Terms
OEE (Overall Equipment Effectiveness)
OEE is the key metric for machine and equipment productivity. It combines availability, performance, and quality into a single percentage value.
Lead Time
Lead time measures the total duration from order receipt to delivery -- including all waiting, storage, and transport times. It determines delivery capability.
SMED (Single Minute Exchange of Die)
SMED is a method for drastically reducing setup times. Goal: Every changeover in under 10 minutes -- in the single-digit minute range.
Value Stream Mapping (VSM)
Value Stream Mapping visualizes the entire material and information flow of a product -- from raw material to customer. It makes waste and bottlenecks visible at a glance.
