How does a Project Manager add value to an Agile Scrum team?
written by gunther gerlach-2009
Definition: Agile project management is as radically different from traditional project management as agile processes are different from traditional methodologies. Rather than plan, instruct and direct, the agile project manager facilitates, coaches and leads.
Recently I came across of someone posting about the value of a PM in an Agile Scrum environment. It’s been a long time from most of the companies realized the important role of PMs But it looks like some Scrum process consultants, after run out of ideas to justify the PM’s role, they just wants to get rid off them… big mistake
Cloud Computing
written by gunther gerlach-2009
Everyone has an opinion on what is cloud computing. It can be the ability to rent a server or a thousand servers and run a geophysical modeling application on the most powerful systems available anywhere. It can be the ability to rent a virtual server, load software on it, turn it on and off at will, or clone it ten times to meet a sudden workload demand. It can be storing and securing immense amounts of data that is accessible only by authorized applications and users. It can be supported by a cloud provider that sets up a platform that includes the OS, Apache, a MySQL database, Perl, Python, and PHP with the ability to scale automatically in response to changing workloads.
Service Mediation and Adaptation
written by gunther gerlach-2009
The assimilation of services through service ecosystems presents major integration development and maintenance costs. Service providers need to compose their services effectively in coordination with other services if they are to engage in oncoming market opportunities and situations. Further up the supply and distribution chain, if services are to be brokered and delivered through other intermediaries (e.g., for authentication, payment, device-specific service presentations), they will need to be interfaced with service delivery components that operate in various ways. Thus, one can expect that services will have to interact with one another in ways not necessarily foreseen during their development or deployment. A key challenge in this setting is service mediation: the act of repurposing existing services so that they can interact in unforeseen manners by intercepting, storing, transforming, and routing messages going into and out of these services.
Service Quality Management
written by gunther gerlach-2009
In wider spanning service ecosystems, several service providers may offer functionally replaceable services that differ in their extra-functional characteristics, such as usage terms and quality of service delivery. Service providers need to be responsive – potentially in real-time – to negotiate variations of service delivery requirements (e.g., price, deliverable timetable). Service ecosystems should therefore explicitly support the negotiation process, reducing non-critical human involvement and providing decision-makers with the information they require to formulate and assess service offers.
Conversational Service Interactions

Internet commerce has created newer forms of service interactions than traditional marketplace transactions. Amazon/UKOnline, single-consumer-to-service transactions – e.g., making customer listings, doing basic look-ups and verification checks, and purchasing goods – are giving way to more distributed, pull-oriented and data streaming modes of interaction on the web. Marketplace auctions, voting, and subscription-based RSS feeds are enhancing wider spans of participants and semistructured, audio and video data in conventional transactional forms.
