In the world of continuous improvement and operational excellence, the Improve phase of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology represents a critical turning point. This is where organizations transform insights from data analysis into concrete actions that streamline operations, reduce waste, and enhance overall performance. Process simplification stands at the heart of this transformation, offering a systematic approach to eliminating unnecessary complexity while maintaining or improving output quality.
Understanding Process Simplification in the Improve Phase
Process simplification is not merely about cutting steps or reducing resources. It involves a comprehensive evaluation of existing workflows to identify redundancies, bottlenecks, and non-value-adding activities. The goal is to create leaner, more efficient processes that deliver superior results with fewer resources and less time.

The Strategic Foundation for Process Simplification
Establishing Clear Objectives
Before embarking on process simplification, organizations must define specific, measurable objectives. These might include reducing cycle time by 30%, decreasing defect rates by 50%, or eliminating 25% of process steps. Clear objectives provide direction and enable teams to measure success accurately.
Identifying Value-Adding Activities
A fundamental principle of process simplification involves distinguishing between value-adding and non-value-adding activities. Value-adding activities are those for which customers are willing to pay, as they directly contribute to product or service quality. All other activities should be scrutinized for potential elimination or reduction.
Key Strategies for Process Simplification
Strategy 1: Eliminate Redundant Steps
Many processes accumulate unnecessary steps over time, often as workarounds for problems that no longer exist. Consider a manufacturing company that discovered their quality inspection process included three separate approval stages. By analyzing historical data, they found that the first approval caught 85% of defects, while the second and third approvals combined caught only 5% more. The remaining 10% of defects were systemic issues that no inspection level caught.
By eliminating two redundant approval stages and addressing the systemic issues, the company reduced their inspection time from 6 hours to 2 hours per batch while maintaining quality standards. This translated to processing 50 additional batches monthly, representing a significant capacity increase without additional resources.
Strategy 2: Automate Manual Processes
Automation represents one of the most powerful tools for process simplification. However, it is crucial to simplify processes before automating them. As the saying goes, automating a bad process simply gives you a faster bad process.
A customer service department handling insurance claims provides an excellent example. Initially, representatives manually entered data from claim forms into five different systems, taking an average of 45 minutes per claim. After process mapping revealed that 70% of the data entry was duplicative, the team simplified the workflow by consolidating systems and implementing automated data capture technology. The result was a reduction in processing time to just 12 minutes per claim, while error rates dropped from 8% to less than 1%.
Strategy 3: Standardize Variations
Unnecessary variation often creates complexity that increases costs and cycle times. Standardization allows organizations to develop expertise, reduce training time, and improve consistency.
A hospital system discovered they were using 47 different vendor products for a common surgical procedure across their network. By standardizing to three preferred products based on clinical effectiveness and cost, they simplified procurement, reduced inventory carrying costs by 35%, and improved surgical outcomes through consistent product performance. The standardization also enabled volume pricing negotiations that saved the system $2.3 million annually.
Strategy 4: Parallel Processing
Many processes are designed sequentially when parallel processing could significantly reduce cycle time. This strategy involves identifying activities that do not depend on each other and can be performed simultaneously.
A software development company reduced their product release cycle from 12 weeks to 7 weeks by implementing parallel processing. Previously, quality assurance testing began only after development was 100% complete. By restructuring the process so testing began when development reached 40% completion, with continuous integration of tested modules, they maintained quality while cutting 5 weeks from the timeline.
Strategy 5: Simplify Decision-Making Processes
Complex approval hierarchies and decision-making processes often slow operations without adding substantial value. Empowering frontline employees with clear guidelines and decision-making authority can dramatically simplify processes.
A retail organization simplified their merchandise return process by empowering store associates to approve returns up to $500 without manager authorization, based on simple criteria. Previously, all returns required manager approval, creating bottlenecks during busy periods. Post-implementation data showed that customer satisfaction scores improved by 28%, average transaction time decreased by 4 minutes, and the rate of inappropriate returns actually decreased by 12%, as the clear criteria provided better guidance than the previous subjective manager approval system.
Implementing Process Simplification: A Practical Example
Consider a financial services company processing loan applications. Their initial process involved 23 steps spanning four departments with an average cycle time of 18 days. Analysis revealed several opportunities for simplification:
Baseline Metrics:
- Total process steps: 23
- Average cycle time: 18 days
- Number of handoffs: 12
- Rework rate: 22%
- Customer satisfaction score: 6.2 out of 10
The improvement team implemented multiple simplification strategies:
- Eliminated 7 redundant verification steps that duplicated information checks
- Automated credit score retrieval and initial eligibility assessment
- Consolidated two separate document review stages into one comprehensive review
- Implemented parallel processing for property appraisal and employment verification
- Empowered loan officers to approve applications under $250,000 without committee review
Post-Implementation Metrics:
- Total process steps: 11
- Average cycle time: 7 days
- Number of handoffs: 5
- Rework rate: 8%
- Customer satisfaction score: 8.7 out of 10
The simplified process resulted in a 61% reduction in cycle time, 64% reduction in rework, and 40% improvement in customer satisfaction. Additionally, the organization could process 85% more applications with existing staff, significantly improving revenue potential.
Measuring the Impact of Simplification
Successful process simplification requires robust measurement systems to validate improvements and identify opportunities for further refinement. Key performance indicators should include:
- Cycle time reduction percentage
- Cost per transaction or unit
- Defect or error rates
- Customer satisfaction scores
- Employee satisfaction and engagement metrics
- Capacity utilization improvements
Regular monitoring ensures that simplified processes remain effective and do not gradually accumulate complexity over time, a phenomenon known as process creep.
Overcoming Resistance to Process Simplification
Change management represents a critical component of successful process simplification. Employees may resist changes due to comfort with existing methods, fear of job loss, or skepticism about new approaches. Effective strategies for overcoming resistance include:
- Involving frontline employees in identifying simplification opportunities
- Communicating the rationale and benefits clearly and repeatedly
- Providing comprehensive training on new processes
- Celebrating early wins to build momentum
- Addressing concerns transparently and promptly
The Role of Technology in Process Simplification
Modern technology tools can significantly accelerate process simplification efforts. Process mapping software helps visualize current and future states, making it easier to identify simplification opportunities. Data analytics platforms enable teams to identify patterns and bottlenecks that may not be apparent through observation alone. Workflow automation tools can eliminate manual handoffs and reduce cycle times.
However, technology should serve the simplified process, not drive it. The most effective approach involves simplifying first, then determining which technologies can further enhance the streamlined process.
Sustaining Simplified Processes
Process simplification is not a one-time event but an ongoing commitment. Organizations must establish mechanisms to maintain simplified processes and prevent complexity from creeping back in. This includes regular process audits, continuous monitoring of performance metrics, and fostering a culture that values simplicity and efficiency.
Documentation plays a crucial role in sustainability. Clear, accessible process documentation helps new employees understand simplified workflows and provides a baseline for future improvement initiatives.
