Logosworld.com Orchestration Replaces Orders  SOA is designed to be built on convergence instead of linearity  Linear models will imperatively fail  SOA requires an implementation independent from sequence  Wikis are best prove of concept!  SOA is designed to be built on convergence instead of linearity  Linear models will imperatively fail  SOA requires an implementation independent from sequence  Wikis are best prove of concept!

Logosworld.com SOA Management  Team Organisations  Teams are tailored to subject matters (“segregation of concerns”) Business needs not organization shall drive team setup  Every team is led by an IT and a business expert Assures a balance between business and technical  The leaders of a team can be from several teams It is actually encouraged that the responsibles roam teams  Every team has at least one member who is a subject expert in another team This assures that knowledge is transportable and communicated  Team Organisations  Teams are tailored to subject matters (“segregation of concerns”) Business needs not organization shall drive team setup  Every team is led by an IT and a business expert Assures a balance between business and technical  The leaders of a team can be from several teams It is actually encouraged that the responsibles roam teams  Every team has at least one member who is a subject expert in another team This assures that knowledge is transportable and communicated

Logosworld.com SOA Management  Project Timing and Conduct  SOA projects are non-linear  Self-Containment Ideally no single object‘s implementation or change should block other activities  Interface Stability Every system build interfaces first Dummy responses can replace fully functionality  Self-Test and Sample-Use Every service needs to prove its full functionality in a self-test Every set-up needs to be demonstrated by a sample service  Project Timing and Conduct  SOA projects are non-linear  Self-Containment Ideally no single object‘s implementation or change should block other activities  Interface Stability Every system build interfaces first Dummy responses can replace fully functionality  Self-Test and Sample-Use Every service needs to prove its full functionality in a self-test Every set-up needs to be demonstrated by a sample service

Logosworld.com SOA Management  Team Management  Team leaders recruit their members Imagine it like „street-football“, captains are elected and then pick „their“ players  Every team has fully responsibility for subject  Every team knows the core tasks of other teams  Teams can ask other teams for „services“  Management is the „Captain“ of the project  Captain decides about course  Captain is umpire between teams  Team Management  Team leaders recruit their members Imagine it like „street-football“, captains are elected and then pick „their“ players  Every team has fully responsibility for subject  Every team knows the core tasks of other teams  Teams can ask other teams for „services“  Management is the „Captain“ of the project  Captain decides about course  Captain is umpire between teams

Logosworld.com Global Project Service Providers  Project head understood as the „Captain“ of all teams  Project coach as main mediator and arbitre  Secretary for logistics  Central service for hotel, travel, expenses, shopping...  Professional language translator  Developer or consultants MUST not do translations  Project head understood as the „Captain“ of all teams  Project coach as main mediator and arbitre  Secretary for logistics  Central service for hotel, travel, expenses, shopping...  Professional language translator  Developer or consultants MUST not do translations

Logosworld.com Reporting Teams reports disorders Teams reports disorders ©2005 Angeli/Grice logosworld.com

Logosworld.com Example of project disorders  Delays in delivery of service interfaces  Quality deficiencies  Illicit side-effects of implementations  Violation of self-containment commandment  Overuse of ressources  Overloading from work  Delays in delivery of service interfaces  Quality deficiencies  Illicit side-effects of implementations  Violation of self-containment commandment  Overuse of ressources  Overloading from work

Logosworld.com Project Timing  Plan is built around sync-points (mile- stones) only  Only deviations from target are reported to captain  Teams agree sync-points themselves  An arbitration commitee resolves contention  Plan is built around sync-points (mile- stones) only  Only deviations from target are reported to captain  Teams agree sync-points themselves  An arbitration commitee resolves contention

Logosworld.com Real Life Analogy of Social Development  Pre-urban village  Every farmer needed to be allrounder smith, miller, baker etc.  Every settlement needed to cater for water, energy and fortification  Superior inventions in one village might not be spread out and be forgotten eventually  Costs for automation and infrastructure very high  Pre-urban village  Every farmer needed to be allrounder smith, miller, baker etc.  Every settlement needed to cater for water, energy and fortification  Superior inventions in one village might not be spread out and be forgotten eventually  Costs for automation and infrastructure very high  City  Sophisticated tasks are delegated to specialists Miller, Baker, Smith etc.  Common and efficient infrastructure  Speedy evolution intensive reuse  Cost efficiency Redundancy is avoidable

Logosworld.com Why Wikis Work and Projects Don‘t

Logosworld.com Loosing Money in Development  Classical Isolated Tasks  One developer programs end to end + one responsible - needs detail knowledge in all areas - all developers need detail knowhow - likelyhood of redundent work - very few reuse of components - risk of developer autism  Team organisation  Several developer (even on small tasks) - Project know how distributed + experts do expert works + high degree of reuse + communication and collaboration mandatory  Classical Isolated Tasks  One developer programs end to end + one responsible - needs detail knowledge in all areas - all developers need detail knowhow - likelyhood of redundent work - very few reuse of components - risk of developer autism  Team organisation  Several developer (even on small tasks) - Project know how distributed + experts do expert works + high degree of reuse + communication and collaboration mandatory

Logosworld.com Societies produced different management strategies Imperative, devote, chaotic Imperative, devote, chaotic ©2005 Angeli/Grice logosworld.com

Logosworld.com What The Others Do?  Imperative  Military Works with small teams and linear tasks Suitable within a team but not to control collaboration  Devote  Abbey Only suitable for ambitious, small and sworn in teams Typically found in science and labs  Chaotic  Orchestra The only choice starting from a certain team size Used also for meta management Most projects follow the orchestra principle Often they are in contention with governance ruling  Imperative  Military Works with small teams and linear tasks Suitable within a team but not to control collaboration  Devote  Abbey Only suitable for ambitious, small and sworn in teams Typically found in science and labs  Chaotic  Orchestra The only choice starting from a certain team size Used also for meta management Most projects follow the orchestra principle Often they are in contention with governance ruling
