    About Three Sigma Manufacturing

    Three Sigma Manufacturing, Inc. is a precision manufacturing company based in Kent, Washington serving aerospace, defense, and industrial customers. Like many high-mix manufacturers, the company faced increasing planning complexity as demand, machine utilization, labor constraints, and customer expectations continued to grow.

    Marcus Crockett, Production Planner at Three Sigma Manufacturing
    "My stress level as the scheduler at Three Sigma since we've gotten Skody has way gone down."

    A Day in the Life of a Scheduler

    How Three Sigma Starts Every Morning

    Every morning begins with a fresh view of current factory conditions. Rather than managing yesterday's schedule, Three Sigma evaluates today's reality and adjusts accordingly.

    Inside Skody

    The Most Important Screen in Skody

    According to Marcus, the Delivery Map is the most valuable screen in the platform because it immediately shows where delivery performance is trending and where future problems are developing.

    Bottleneck Analysis โ€” planners see exactly where time is being lost so they can intervene before customer commitments slip.

    Delivery Map

    A live view of every customer commitment. Planners instantly see which orders are trending late and which are safe.

    Bottleneck Analysis

    Lead time decomposed into production work, material waits, and bottleneck delays โ€” so planners know where to act.

    Resource & Capacity View

    Capacity across 47 machine work centers mapped against current demand so planners can rebalance load before it becomes a problem.

    Machine work centers scheduled

    The full shop is modeled, not just a subset of machines or departments.

    1 Week โ†’ 1 Year

    Planning horizon extended

    Planners can see a full year ahead without locking the shop into a frozen schedule.

    ~99%

    Baseline accepted

    The planner accepts the computed baseline about 99% of days rather than rebuilding it.

    4 Weeks

    Plan visibility

    Production managers took a week off and the floor kept running, because the plan was visible four weeks out.

    Ken Frenkel, CEO of Three Sigma Manufacturing
    "Our people are able to use it readily. The bigger reason is probably that they like to use it. It makes their job easier. I've got several people here now who, if we said we're getting rid of Skody, they'd be very unhappy."

    Ken Frenkel

    CEO, Three Sigma Manufacturing

    Why scheduling first

    The Production Schedule Is the Independent Variable

    "Once you have a production schedule, everything else comes from that. Do you make your delivery date? What does revenue look like? You know delivery dates and you know your customers' terms, so now you know cash flow. Fundamentally, the production schedule is the independent variable. Everything else is a dependent variable."

    Ken Frenkel

    CEO, Three Sigma Manufacturing

    Why It Matters

    Manufacturing Conditions Change Every Day

    Most scheduling systems create a plan from a static snapshot. The problem is that the snapshot becomes outdated the moment production changes.

    Skody reads the current state of production and recalculates the schedule โ€” on demand, on a significant ERP change, or continuously where wired โ€” based on what is actually happening on the floor.

    The result is a schedule planners can trust.

    Frequently Asked Questions

    What can Skody do that Excel cannot?

    Skody recalculates schedules on demand, on a significant ERP change, or continuously where wired, using live production data, labor availability, machine capacity, and material readiness. Excel schedules must typically be updated manually.

    Does Skody consider material availability?

    Yes. Material readiness is treated as a scheduling constraint and is included in planning calculations.

    Can Skody handle machine downtime?

    Yes. When conditions change, Skody recalculates the affected portion of the schedule and highlights delivery impact.

    How does Skody handle an overbooked schedule?

    Skody does not assume every order can be delivered on time. When demand exceeds available capacity, Skody shows which jobs will slip, identifies the constraints causing delays, and allows planners to evaluate staffing, overtime, outsourcing, or sequencing changes before committing to customers.

    How long does implementation take?

    Most customers begin seeing value within weeks, not months.
