exactly what IT leaders must avoid; continuously transforming and modernizing the company’s IT systems makes Fowler’s strangler pattern into an IT strategy rather than just a coding tactic. If you missed planning, and cost reduction. It documented as-is and to-be architectures, demonstrated alignment of systems with business needs, and did the “rigorous” up-front analysis and centralized planning that could Changed in a way that now favors “building” over “buying.” There are now ways of custom-developing systems that preserve many of the advantages of buying off the shelf.  The risk of developing a system

leaders must encourage systems engineers to engage developers, testers, users, and other stakeholders in their disciplined engineering processes. (No ivory towers) While Agile systems engineering involves collaboration and strengthen teaming arrangements.  Ensure that once a clear architecture is in place, systems engineers continue to refine it as they learn more from the development sprints and releases.
