Process optimization sounds like a consulting buzzword. But it's not. It's the fastest way to make your company more efficient – without new hires, without major investments. In this article, we show you 7 proven methods you can apply immediately.

What is Process Optimization?

Process optimization means: analyzing and improving existing workflows.

The goal:

  • Less time for the same task
  • Fewer errors in the workflow
  • Lower costs for the same output
  • Better quality for the customer

The difference from automation: Process optimization comes FIRST. Automating a bad process just means producing bad results faster.

The 7 Most Effective Methods

1. Value Stream Mapping

What is it?

You map out the complete process – every step, every wait time, every handoff point. Then you distinguish:

  • Value-adding: The customer would pay for it
  • Necessary but not value-adding: Must be done, but no direct value
  • Waste: Neither value nor necessary

How to do it:
  • Document process from start to finish
  • Measure times (processing time vs. wait time)
  • Categorize each step
  • Eliminate waste
  • Example: Quote Creation
    StepTimeWait TimeCategory
    Request arrives-2hWait
    Read request5min-Necessary
    Search data in CRM10min-Waste
    Calculate pricing30min-Value-adding
    Wait for approval-24hWait
    Format quote20min-Necessary
    Send2min-Value-adding
    Insights:
    • 26h total lead time
    • Only 32min actual work
    • 10min pure waste (CRM search)
    • 26h wait time = 97% of the time

    Quick Win: Automate CRM integration, speed up approval process

    2. The 5-Why Method

    What is it?

    For every problem, ask "Why?" 5 times – until you get to the root cause.

    How to do it:

    Problem: Customers are complaining about late deliveries.

  • Why are deliveries late?
  • - Because shipping happens in the afternoon.

  • Why does shipping happen in the afternoon?
  • - Because picking takes so long.

  • Why does picking take so long?
  • - Because items have to be searched for in the warehouse.

  • Why do items need to be searched for?
  • - Because storage locations aren't maintained in the system.

  • Why aren't storage locations maintained?
  • - Because goods receipt doesn't include booking.

    Solution: Improve goods receipt process – not extend shipping times.

    3. PDCA Cycle (Plan-Do-Check-Act)

    What is it?

    A continuous improvement cycle in 4 steps.

    How to do it: Plan:
    • Identify problem
    • Collect data
    • Develop solution
    • Define success criteria

    Do:
    • Test solution on a small scale
    • Pilot with one department/team
    • Document what happens

    Check:
    • Measure results
    • Compare with expectations
    • What worked? What didn't?

    Act:
    • If successful: Roll out broadly
    • If unsuccessful: Adjust and restart
    • Establish standards

    Example:
    Plan: Support tickets should be answered in 4h instead of 24h
    

    → Solution: Templates for common inquiries

    Do: Pilot with 3 support staff, 2 weeks

    Check: Average response time now 6h

    → Better, but goal not reached

    → Insight: 40% of inquiries don't fit any template

    Act: Expand templates, introduce AI categorization

    → Start new PDCA cycle

    4. Bottleneck Analysis (Theory of Constraints)

    What is it?

    Every process is only as fast as its slowest point. Find and eliminate the bottleneck.

    How to do it:
  • Identify: Where does it back up?
  • Exploit: Maximize bottleneck utilization
  • Subordinate: Adjust everything else to the bottleneck
  • Elevate: Increase bottleneck capacity
  • Repeat: Find the next bottleneck
  • Example: Customer Service
    Incoming requests: 100/day
    

    → Level-1 Support: 120/day capacity (ok)

    → Level-2 Support: 40/day capacity ← BOTTLENECK

    → Developers: 80/day capacity (ok)

    Not the solution: Hire more Level-1 support The solution: Relieve Level-2 (training, tools, redistribution)

    5. Standardization (SOPs)

    What is it?

    Standard Operating Procedures – everyone does the same process the same (best) way.

    Why is it important?
    • No dependency on individual people
    • Faster onboarding
    • Measurable improvement possible
    • Foundation for automation

    How to do it:
  • Observe your best employee
  • Document their workflow
  • Refine with the team
  • Train everyone
  • Update regularly
  • SOP Template:
    PROCESS: [Name]
    

    VERSION: [1.0]

    LAST UPDATE: [Date]

    OWNER: [Name]

    OBJECTIVE:

    What should be achieved at the end?

    PREREQUISITES:

    What must be done beforehand?

    STEPS:

  • [Specific instruction]
  • → System: [Which tool]

    → Screenshot/example if needed

  • [Specific instruction]
  • ...

    EXCEPTIONS:

    If X, then Y instead of Z.

    SUCCESS CRITERIA:

    How do I know it's done correctly?

    COMMON ERRORS:

    • Error 1: How to avoid
    • Error 2: How to avoid

    6. Eliminating the 8 Wastes (Lean)

    What is it?

    Lean Manufacturing identifies 8 types of waste. These can be applied to any office process.

    WasteProductionOffice
    TransportMoving materialForwarding documents
    InventoryStockUnprocessed emails
    MotionWalking distancesSwitching between systems
    WaitingMachine idleWaiting for approval
    OverproductionProducing too muchReports nobody reads
    Over-processingExcessive qualityPerfectionism
    DefectsScrapCorrecting errors
    TalentUnused skillsExperts doing routine tasks
    Quick-Check for Your Process:
    Is information forwarded multiple times?
    Are there backlogs/queues?
    Do employees switch between many systems?
    Do tasks wait for approvals?
    Are reports created that nobody uses?
    Is rework/correction needed?
    Are overqualified employees doing routine tasks?

    7. Automation (as the Last Step)

    What is it?

    Only after you've optimized do you automate the improved process.

    Why last?
    • Automated garbage = faster garbage
    • First understand, then automate
    • An optimized process is easier to automate

    What to automate:
    AutomateDon't Automate
    Rule-basedCreative decisions
    RepetitiveOne-time tasks
    Time-intensiveAlready fast
    Error-proneWorks reliably
    Data transferComplex judgments

    Process Optimization in Practice: An Example

    Initial Situation: Travel Expense Reporting

    Current process:

  • Employee collects receipts (physical)
  • Employee fills out Excel form
  • Employee prints and signs
  • Employee submits to supervisor
  • Supervisor reviews and signs
  • Document goes to accounting
  • Accounting checks receipts individually
  • Accounting enters into system
  • Finance approval
  • Payment
  • Problems:
    • Lead time: 3 weeks
    • Error rate: 40% (wrong amounts, missing receipts)
    • Time spent: 45 minutes per report

    After Optimization:
  • ~~Employee collects receipts (physical)~~ → App photographs receipts
  • ~~Employee fills out Excel form~~ → App extracts data via OCR
  • ~~Employee prints and signs~~ → Digital confirmation
  • ~~Employee submits to supervisor~~ → Automatic routing
  • Supervisor reviews and approves (digital, 2 clicks)
  • ~~Document goes to accounting~~ → Automatic
  • ~~Accounting checks receipts individually~~ → AI pre-check, only exceptions manual
  • ~~Accounting enters into system~~ → Automatic import
  • ~~Finance approval~~ → Rule-based automatic up to threshold
  • Payment (automatic at month end)
  • Result:
    • Lead time: 3 days
    • Error rate: 5%
    • Time spent: 5 minutes per report

  • Common Mistakes in Process Optimization

    1. Too Much at Once

    Better: One process, one improvement, then next step.

    2. Optimizing Without Data

    Better: First measure, then improve, then measure again.

    3. Asking the Wrong People

    Better: Talk to the people doing the work, not just management.

    4. Seeking Solutions Before Understanding the Problem

    Better: 5-Why method, find root cause.

    5. Treating Optimization as a One-Time Project

    Better: Continuous improvement, PDCA as routine.

    Conclusion

    Process optimization is not rocket science. It's systematic observation, asking questions, and improving. The biggest gains are often in the obvious:

    • Eliminate wait times
    • Avoid duplicate work
    • Establish standards
    • Only then automate

    Start with one process. Today. Not perfect, but start.
