What is a Practice?Community There are individuals and organizationswho are associated with the practice. (Medicine is associated with doctors andclinics.)Instrumental (Functional) It should perform some function. (Medicine is associated with keepingpeople healthy and fighting disease.)Conceptual (Discursive) It should offer a language for reasoningand talking about things. (Doctors can communicate with oneanother, and with other practitioners suchas pharmacists.)Knowledge-based There is some body of knowledge that isavailable to practitioners. (In the case of medicine, this includesanatomy, physiology and biochemistry.)Service There is a way in which practitionersengage with the subject. (There are established ways for patientsto visit doctors, and for doctors to bepaid.)What is EA? When people talk about EnterpriseArchitecture, they may mean any or all ofthe above.
Which Practice? An individual or team customizes aframework for a specific project ororganization. The project or organization deviates fromthe official framework in various ways. Adding and subtracting activities Simpler or more complicated pathways Links to other frameworks Use of available tools A project may be retrospectively massagedto comply with an official framework. The participants may be more or lessaware of any deviations and theirconsequences.Official• What thebook saysEmergent• What thecommunitydoesEspoused• What theteam thinksit is doingIn-Use• What theteamactuallydoes

Who are the sage kings?(How many can you recognize?)
Four Prong Method (Veryard)Effective There is some evidence that it worksand delivers value.Grounded There is some explanation why itworks. The explanation is oftenexpressed as some form of theory.Coherent Not just random collections of ideasand tools, but having a meaningfulidentityProgressive Capable of learning systematicallyfrom experience, and adapting itselfto new situations. Don’t take results at face value Don’t take participants’theories at face value2x Caution
