An overview of what value engineering is, its history, principles, and objectives. This topic will cover the importance of value engineering in improving quality, reducing costs, and enhancing overall project performance.
Introduction to Value Engineering (VE)
Purpose: Maximize function while minimizing cost without compromising quality, safety, or performance.
| Aspect | Definition |
|---|---|
| Core Idea | Systematic, interdisciplinary method to improve the “value” of a product, service, or process. |
| Value = Function / Cost | Value increases when the functional performance rises, the cost falls, or both. |
| Origin | Developed during WWII by the U.S. Navy to reduce material usage while maintaining ship performance. |
| Scope | Applies to: design, construction, manufacturing, maintenance, services, and even organizational processes. |
| Principle | Explanation |
|---|---|
| Function‑Oriented | Focus on what a product does, not how it is currently made. |
| Team‑Based | Multidisciplinary team (engineers, designers, cost analysts, users) brings diverse perspectives. |
| Life‑Cycle Perspective | Considers acquisition, operation, maintenance, and disposal costs. |
| Creative & Analytical | Generates alternatives (creative) then evaluates them quantitatively (analytical). |
| Objective Evaluation | Decisions are based on data (cost, performance, risk) rather than personal preference. |
| Phase | Goal | Typical Activities |
|---|---|---|
| 1. Information | Gather all relevant data. | • Define project scope, objectives, constraints. • Collect drawings, specs, cost data, performance criteria. • Identify stakeholder needs. |
| 2. Function Analysis | Identify and rank essential functions. | • Write FAST (Function Analysis System Technique) diagram. • Classify functions: primary (core) vs. secondary (support). • Assign Function Cost (cost per unit of function). |
| 3. Creative (Brainstorming) | Generate many possible ways to achieve each function. | • Use “no‑judgment” brainstorming. • Encourage wild ideas. • Record all concepts for later screening. |
| 4. Evaluation | Screen concepts for feasibility & value. | • Apply criteria: cost, performance, risk, schedule. • Use Weighted Scoring or Cost‑Benefit Ratio. • Short‑list viable alternatives. |
| 5. Development | Refine selected alternatives into detailed proposals. | • Perform engineering calculations, simulations, prototypes. • Develop cost estimates, schedule impacts. • Conduct risk analysis (e.g., FMEA). |
| 6. Presentation | Communicate recommendations to decision‑makers. | • Prepare VE report (objectives, analysis, recommendation, savings). • Include Implementation Plan (phasing, responsibilities). |
| 7. Implementation & Follow‑up | Apply approved changes and verify results. | • Execute design/modification. • Track actual cost savings vs. forecast. • Document lessons learned. |
The phases are often depicted as a VE Job Plan (a linear flow) but can be iterative.
Identify Functions – “What does it do?”
Write Functions in Two‑Word Form – Verb + Noun (e.g., Transport fluid, Support load).
