Explanation

Using standards in specification is very convenient. They reduce the time and effort to produce. They tend to be very accurate with correct technical terminologies. They are well recognised and accepted by a wide range of suppliers and buyers. However, since a standard is very specific, complex and lengthy, it requires a lot of time to be drafted and approved. Therefore, standard tends to be static and don't encourage innovation. It may also not accommodate latest technology and trends.

Explanation

Value Engineering (VE) is concerned with new products. It is applied during product development. The focus is on reducing costs, improving function or both, by way of teamwork-based product evaluation and analysis. This takes place before any capital is invested in tooling, plant or equipment.

This is very significant, because according to many reports, up to 80% of a product’s costs (throughout the rest of its life-cycle), are locked in at the design development stage. This is under-standable when you consider the design of any product determines many factors, such as tooling, plant and equipment, labour and skills, training costs, materials, shipping, installation, maintenance, as well as decommissioning and recycle costs.

Explanation

There are three basic groups of WLC (whole life-cycle costing) models:

- Decision support models

- Simulation models: Life cycle cost is an essential approach to decide on alternative rehabilitation strategies for infrastructure systems. Monte Carlo simulation approach is used to develop a stochastic life cycle cost (SLCC) model and methodology in order to compare different rehabilitation scenarios/alternatives for infrastructures, such as water mains. This method assumes that some inputs are randomly variable in a range of values.

- Optimisation models

Explanation

Design specification is a detailed document providing a list of points regarding a product or pro-cess. For example, the design specification could include required dimensions, environmental fac-tors, ergonomic factors, aesthetic factors, maintenance that will be needed, etc. It may also give specific examples of how the design should be executed, helping others work properly (a guideline for what the person should do).

Performance specification is written requirement that describes the functional performance criteria required for a particular equipment, material, or product.

Tolerance is the permissable limit of a variable used to define a product

Statement of work is the document that captures and defines all aspects of a project, including the activities, deliverables and the timetable for the project.
