Understanding and Distinguishing Between Two Types of Improvements

Quality improvement is a backbone concept in the CQIA Body of Knowledge, emphasizing continuous efforts to increase overall process or product performance. Typically, these improvements fall into two main types: incremental improvements and breakthrough improvements. Although both seek enhancement, the approach, steps, and situations where each type is expected differ significantly.

Incremental improvements refer to small, gradual changes made consistently over time. These usually involve refining existing processes by eliminating inefficiencies, reducing waste, or simplifying steps. The goal is continuous improvement without drastic disruption.

On the other hand, breakthrough improvements aim for significant, often step-change enhancements. These are typically large-scale, innovative changes that substantially alter how a process operates or how products are developed, often resulting from deep analysis or revolutionary ideas.

Steps Required for Incremental Improvement

Incremental improvement usually follows a repetitive, methodical cycle similar to the Plan-Do-Check-Act (PDCA) approach. Here are the typical steps:

Identify small improvement opportunities: Look for minor process weaknesses or inefficiencies that can be enhanced without major changes.
Plan the change: Develop a small, manageable action plan to implement the improvement.
Implement the change: Carry out the modification on a limited scale.
Measure and analyze results: Gather data to determine if the change led to improvements.
Standardize the change: If successful, make the new method the standard operating procedure.
Repeat the cycle: Continue seeking small opportunities for continuous improvement.

Steps Required for Breakthrough Improvement

Breakthrough improvement involves a more strategic and systemic approach, often necessitating collaboration across functions. The steps usually include:

Identify major problem or opportunity: Recognize a critical issue or large gap that cannot be fixed by small tweaks.
Form an improvement team: Typically, cross-functional with diverse knowledge to identify innovative solutions.
Conduct deep root cause analysis: Use tools like cause-and-effect diagrams or process mapping to understand underlying issues.
Develop a creative, substantial solution: Propose a new way of doing things or a big process redesign.
Pilot the solution: Test on a small scale to assess impact and feasibility.
Analyze the results and adjust: Review data carefully and refine before full-scale deployment.
Implement broadly and standardize: Roll out the breakthrough change as the new baseline procedure.

Type of Situations Expected for Each Improvement Type

Incremental improvements are best suited for stable processes where only slight optimization is needed. For example, reducing paperwork errors by adding a checklist or improving customer response time by reorganizing staff duties slightly fits into incremental changes. These improvements are common in daily quality team activities and are often ongoing.

Breakthrough improvements are necessary when a process faces significant challenges, outdated technology, or performance far below expectations. For example, redesigning a manufacturing line to incorporate automation or overhauling a customer feedback system to integrate new software is breakthrough improvement. These changes involve more risk but promise substantial gains.

Understanding these differences ensures CQIA candidates can quickly recognize the type of improvement being discussed on the exam and in real work scenarios.

Real-life example from quality improvement associate practice

Imagine a Certified Quality Improvement Associate joining a cross-functional team tasked with reducing defects in a small assembly process for electronic components. Initially, the team identifies minor issues like inconsistent part placement and slow inspections.

Using an incremental improvement approach, the team collects data via a check sheet and maps the current process flow. They standardize instructions for part placements and introduce a checklist to ensure inspections are thorough. After a few weeks, defect rates drop by 10% due to these small but effective changes.

Later, larger issues emerge, such as inherent design flaws leading to frequent rework. The team then shifts to a breakthrough improvement mode—conducting detailed cause-and-effect analysis and root cause investigation (5 Whys method). They decide to redesign the fixture holding the components, automating part of the process. Piloting this new setup reduces defects by 40%, substantially improving process capability. The team documents lessons learned and presents the results to management to gain approval for broad implementation.

Question 1: What is a primary characteristic of incremental improvements?

A) They usually involve significant changes requiring substantial resource investment.
B) They aim to create revolutionary, step-change advancements.
C) They consist of small, continuous changes that gradually improve processes.
D) They are only implemented once for long-term effect.

Correct answer: C

Explanation: Incremental improvements focus on making small but continuous enhancements over time, often through minor process adjustments. This gradual approach contrasts with step-change or breakthrough changes.

Question 2: Which step is typically involved in breakthrough improvements but not usually in incremental improvements?

A) Measure current process performance.
B) Conduct deep root cause analysis with cross-functional teams.
C) Standardize small changes after testing.
D) Repeat the improvement cycle continuously.

Correct answer: B

Explanation: Breakthrough improvements often require deep root cause analysis with cross-functional collaboration to develop major solutions, unlike incremental improvements that generally involve smaller scale changes and simpler analysis.

Question 3: In what situation would breakthrough improvement be most appropriate?

A) When minor inefficiencies cause slight delays in workflow.
B) When a process requires a small documentation update.
C) When a process consistently produces defects due to outdated equipment.
D) When routine inspections need to be more thorough.

Correct answer: C

Explanation: Breakthrough improvements are best for situations where substantial changes, such as investing in new equipment or redesigns, can dramatically improve process performance, rather than minor tweaks or documentation fixes.
