The cost of conformance refers to the expenses associated with ensuring that a product or service meets quality standards. This includes activities like quality planning, training, and quality control measures during production.
On the other hand, the cost of non-conformance involves the expenses incurred when a product or service fails to meet quality requirements. This includes the cost of defects, customer complaints, warranty claims, and potential damage to the reputation of the company.
In essence, investing in the cost of conformance aims to prevent defects and ensure quality, while the cost of non-conformance deals with the repercussions of failing to meet quality standards.
Cost of Conformance
1. **Prevention Costs:** These are expenses incurred to prevent defects in products or services. Examples include quality planning, training, process documentation, and implementing quality control measures during production.
2. **Appraisal Costs:** These are costs associated with assessing and evaluating the quality of products or services. Inspection, testing, and quality audits are examples of appraisal costs.
Cost of Non-Conformance
1. **Internal Failure Costs:** These arise when defects are discovered before the product reaches the customer. Examples include the cost of rework, scrapped materials, and downtime due to quality issues.
2. **External Failure Costs:** These occur when defects are identified after the product reaches the customer. External failure costs include warranty claims, product recalls, customer complaints, and potential legal actions.
Understanding and managing both conformance and non-conformance costs is crucial for businesses aiming to deliver high-quality products or services while minimizing the financial impact of defects. It involves a balance between investing in prevention and appraisal to reduce the likelihood of defects and addressing issues promptly when they occur to mitigate external consequences.
➡ Delphi Technique
1️⃣ A way to reach a consensus of experts on a subject, experts on the subject participate in this technique anonymously
2️⃣ A facilitator uses a questionnaire to solicit ideas about the important points related to the subject
3️⃣ The responses are summarized and are then recirculated to the experts for further comments
4️⃣ Consensus may be reached in a few rounds of this process. This helps reduce bias in the data and keep any one person away from having undue influence on the outcome
➡ Wideband Delphi
1️⃣ Wideband Delphi is a variation of the Delphi estimating method where subject matter experts complete multiple rounds of producing estimates individually, with a project team discussion after each round, until a consensus is achieved
2️⃣ For Wideband Delphi, those who created the highest and lowest estimates explain their rationale, following which everyone estimates
3️⃣ The process repeats until convergence is achieved
4️⃣ Planning Poker is a variation of Wideband Delphi
