Tight coupling, metrics and monitoring must be manually compiled for each process involved in a given request. UJlize ESB for all integraJons, taking advantage of locaJon transparency, service metrics, monitoring and problem idenJficaJon capabiliJes Standards and Guidelines Rarely complied with. Varies greatly across features based on team lead/developer preference. Key stakeholder in DTO engagement and technical governance to ensure core KP-‐IT service orientaJon standards are followed. Documenta7on Varies from none to some. Most are not detailed enough to implement to, all different in format and levels of detail Comply with KP-‐IT SOA and SDLC documentaJon requirements for services. Request it of our service providers.
