Many mature organizations evaluate methods and tools, processes, and models regularly to determine their suitability for their business, and whether they may positively impact quality, cycle time, or productivity. Studies in the US and Europe have suggested that there are difficulties in scalability with formal methods and that some developers are uncomfortable with the mathematical notation. Formal methods may be employed for a part or all of the lifecycle and one approach to the deployment of formal methods in an organization is to adopt a phased approach to implementation.
Object-oriented reuse This sub-phase identifies existing objects that may be reused in the implementation. Verification of Design This involves verification to ensure that the design is valid with respect to the specification of the requirements. The verification may consist of a review of the design using a methodology similar to Fagan inspections. Formal methods may be employed for verification of the design and this involves a mathematical proof that the design is a valid refinement of the specification.
There is, of course, no point in measuring for the sake of measuring itself and care is required to ensure that the measurements to be made are closely related to the particular goal. The well-known approach of Goal, Question, Metric (GQM) suggests that the organization first needs to identify the key goals which it is trying to achieve; then it identifies relevant questions which need to be answered to assess the extent to which the goal is being satisfied, and then to formulate a metric to give an objective answer to the particular question.
