  • Patent number: 6675149
    Abstract: A method, system and program product for matching the an information technology enhancement project with the resource and priorities of an enterprise is presented herein. A set of objectives for the information technology resources is defined and prioritized as to their importance to the enterprise. The information technology resources for the enterprise are partitioned into segments along a predetermined common property such as geography or skill-base. Each segment is compared to a set of desire information technology characteristics and a score for each characteristic is assigned to each segment and summed providing a total characteristic score for each segment. The total characteristic score is weighted in light of the prioritized objects by virtue of a correlation created between the objectives and the characteristics.

  • Patent number: 6260020
    Abstract: A method, system and program product for sizing a programming effort associated with the migration of a computer program from a first to a second computer platform is described herein. The size of a computer program is estimated and an adjustment factor is applied to represent a base estimate of the programming effort required for the migration. Analysis of availability of required middleware, object and program libraries may further lead to modification of the estimate. An evaluation of scaling issues related to the migration and a comparison of the programming models for the first and second computer platform may additionally affect the estimate. If the migration port is to be made from a multiple system platform to a single system platform the re-architecting effort to reduce path lengths such as replacing network interfaces with direct file sharing must be added to the base estimate.

  • Patent number: 6249769
    Abstract: The information technology environment and requirements of a business entity are evaluated via an interactive engagement process, system and program product to successively match the entity's needs to a set of information technology solutions so as to generate a business solution deliverables such as a formal solution proposal. The engagement entails the determination of the entity's ability to participate in the evaluation. The engagement next includes partitioning the entity's information technology infrastructure into segments along the lines of established business criteria, receiving profile information from the entity thereon and mapping the profiled segments to potential solutions creating an ordered listing of solutions. Ordered solutions may be selected for detailed investigation including a further profiling of the segment to which the solution is to be applied and a workload analysis of the proffered solution.
