Substitute: Replacing one material with another of less hazard, e.g. cleaning with water and detergent rather than a flammable solvent Moderate : [ 8 ] Reducing the strength of an effect, e.g. having a cold liquid instead of a gas at high pressure, or using material in a dilute rather than concentrated form
Requirements come from different sources, like the business person ordering the product, the marketing manager and the actual user. These people all have different requirements for the product. Using requirements traceability, an implemented feature can be traced back to the person or group that wanted it during the requirements elicitation.
