Assessment of product concepts |
The results from an environmental assessment in the form of figures are not very often of interest as such. These figures do not make sense until they are used in a comparison. You would normally compare different alternatives like:
To be able to conduct a meaningful comparison you have to define the “Functional Unit” of the service the product or the system provides to the customer. The Functional unit must include a qualitative description of the service and quantification. The quantification must specify the duration, including the entire life span of the product.
Some examples of functional units are given below:
| Product | Quantity | Duration | Qualities |
| TV | Receive and present TV programs in colour on a 28” screen | 6 hours pr. day for 10 years | Sharpness of image, Quality of sound, Number of channels, Remote control features |
| Mobile phone | To enable telephone conversation without any physical connection to telephone system. | 30 minutes of conversation and 23½ hours pr. day stand-by for 3 years. | Low weight and volume, Long stand-by time between recharging of batteries, Indicators in the display. Etc. |
| Paint | Protection of 1 m2 of fir surface on an outdoor facade, facing west and exposed to rain and sun. | 10 years | Non-dripping, Colour, Durability in closed container. |
For some products (especially consumer products) you can divide the “Qualities” in some which are an essential part of the functionality and therefore mandatory and others which are used to attract a certain fragment of the customers. This could be features like smart design and certain games for a mobile phone.
When you later (in section 3) quantify the environmental impact this should be consistent with the functional unit.
By referring to the functional unit one will be able to compare different products that have different characteristics like comparing Paint A covering 20m2/liter requiring maintenance every 5th year with Paint B covering 15m2/liter and requiring maintenance every 8th year.
The product has several stakeholders. They all have various environmental expectations to the product and they are all more or less influencing the success the product will obtain on the market. Some of the stakeholders do not refer specifically to the product, but are merely stakeholders to the company as such and not just to a specific product. In this context we will focus on the product/stakeholder relation well knowing that some relations are more company/stakeholder relations.
The most important interested parties are listed below. Dependent on the type of product, the market situation, the employment situation etc. these parties will be of varying importance.
The scope of this assessment on concept level is not to perform a comprehensive “Product chain survey”. The purpose of this is to spot important environmental impacts or expectations related to the product.
