Purchasing software packages need to be part of the strategies therefore to cater for growth, the company needs to include the interface information that is needed between the system and package the company is developing. The company needs to develop and use the CASE design tool where the company will be able to print design diagram and other document from the CASE design tools in the system.The consideration for legacy systems will be an established format in the company especially in the IT management when the situation is migrating from the old to new design where the present solutions are reused. The processes, procedures, and information format needs to be developed in the field. The solutions here entail discarding the system and develop a placement system that is virtual, freezing it, and using it to be a component of a large system. The potential and consideration reuse of legacy production system is solved by using constraint structures and formal requirement especially in the early phases of design and used in the entire structuring and defining terms such as needs, musts, objectives, wishes, and goals. The four elements important in the requirement analysis include the functional requirements, internal design constraints, winning criteria, and external design constraints. Therefore, the consideration for legacy systems will be an established format in the company especially in the IT management when the situation is migrating from the old to new design where the present solutions are.
