Value engineering / value analysis

Simple tool to enable a cross functional team to compare the relative cost of delivering different aspects of a product's functionality. Appropriate for analysing existing designs but also useful when considering product concepts. A good team building exercise, linking market, technical and production knowledge.

Description
Aims to establish the cost of different elements of functionality and answer questions such as:

  • "What is the cost of 'providing comfort' in a car"
  • "What is the cost of 'mixing ingredients' in a bread mixer"

Unique and professional website templates. Vooweb - Website Templates offers a great variety of Website templates for business and personal use | If there has been no improvement since the beginning of your relationship with your SEO company, they need to explain why. Then you have a great seo Company working for you. If you don't want to do it yourself, an SEO company being paid monthly should detail exactly what they are doing for you. | Any link exchanges promising hundreds or links immediately upon joining should be avoided unless the only search engine you care about is MSN. Using a link exchange as the only way you get links will also not be a path you want to wander down. Exchanging links with every site under the sun is also bad.

Whilst a relatively simple analysis, there is an underlying need to have an appropriate understanding of the needs and motivations of customers in order to consider the relative importance of product functions. Specific outcomes may include the elimination of excessive costs due to minor functions or the justification of increased cost for a highly important function. The best results enable an overall increase in functionality, without any increase in costs - added value.

Method

  1. Identify components (or sub-assemblies for complex products)

  2. Identify primary product functions - expressed as a verb and a noun

  3. Estimate component (or sub-assembly costs and calculate the relative cost of each (%)

  4. Estimate the value of each component
    - so that the component cost is spread appropriately amongst the product functions to which it contributes. This can be difficult and it is useful to consider the perceived value to customers. It is at this stage that the team is involved in significant discussion and debate

  5. Calculate the cost of each function and evaluate the relative cost of all functions

  6. Investigate improvements
    Can high cost parts be removed, identify high cost/low value and low cost/high value parts. Ask basic questions - eliminate, reduce, simplify, modify, standardise.
