Member Name:Bokka Satya Saradhi

1) Why does the SAP's three layered architecture never consider the top business layer
as one of the 3 provided architecture solution layers?

2) Physical layer is responsible for exact Goal identification, Policy selection,
managing which layer in three layered architecture takes the responsibilities of the
physical layer in 2 layered architecture ?

3) How does the information technology operations monitor the end to end
environment, to detect the problem , to separate the problem , solve services problems
,which includes compound application that has service to service dependencies?

Critical Questions:
1.How can the “Goal recommender” generate goals to the user? User Perspective is always different, so do you think this as a system that achanges the user perspective in reaching a goal? Is this acceptable?
2.In a policy Oriented Approach, based on specific policies and user specified goals a desired web service chosen from the”web service repository”. What if there is no web service that suits the polices and goals?
3.With just knowing the System state and progress, how far can user understand the system? What if the system behaves differently because of the complex errors in the system? Such a system state is not acceptable, this might deceive the user.

1. The author talks about preconditions that are stopping from realizing the proposed system but, how to overcome them?

2. The author says "Developers must also consider fundamental questions such as the power of expressiveness, granularity of description, scope, and compliance with existing standards". Does the author want us to think in these terms to find solution for the preconditions? Or is it to come up with new systems or ideas?

3. The author proposes a great system but how long do we have to wait to see such a system in action?
4. According to market study 80% of large organizations and 50% - 60% small & medium organizations are expected to adopt SOA only by 2010. So, will these organizations be willing to implement yet another new architecture soon?

a. Enterprises would be changing their policies in accordance to the latest trends to gain profits. So is it appropriate in developing a system that would be based on such policies(which continually changes)?
b. The author advices of having assistants such as guide, explainer etc. Will this not increase the intricacy of the product?
c. As the system should cleverly build a high quality business process from already existing service, will this not lead to enlargement of response time when a planner for dynamic integration is introduced?

1) There are no specific standards specified for the features like the “situation analyzer”, “Goal Recommender” and “Explainer”. These are the services which work based on the predefined prototypes. How can these work in the real time when some exceptional cases rise?

2) The writer mainly explained the features in a non-practical way. How these features do translates the prototypes or the ongoing experiences in to their own machine understandable formats in order to analyze them?

3) The questions raised by the author himself for the “policy-oriented enterprise” like the “Goal Identification”, “ policy selection” etc are my question too.

What precautions are taken to make sure that the use cases developed in transformation phase exactly represents the present states and goal states? If these states were represented incorrectly then the whole system may be ruined, it may result in unwanted goal.

The user may have different requirements. How can explainer suggest a best solution with out perfectly knowing the requirements of the user? The solution which seems to be best from the explainer point of view may not be best from user point of view.

Author suggested having assistants such as situation analyzer, explainer, guide, goal recommender. Does nt it increase the complexity of the product and also cost?

Critical Questions:
1.Can the business object be compared to that of the physical object in all services and all applications ,this is not possible always ,the physical objects are much more flexible to the business objects ,so I would like to ask the author whether this is really possible in all applications?
2.The POEM has been included with 4 components such as situation analyzer, goal recommender, explainer and guide ,how does he justify that these components would suppress all the issues that have come from the SOA ?
3. the authors feels that the Poems’ is the next step in software development ,with such few changes made to SOA, will there be a relationship effect on enterprise management and the issues revolving around it?

Group 5:


1. It was mentioned in the system that this process uses composition of re-usable existing services to achieve the required goals. But, if the services are modified or if the better services are available in the market, does the system able to re-tailor with the new or modified services?

2. It was mentioned that the system uses standards such as SOAP, XML based languages, BPEL and WSDL. Does it support HTML and java script the can perform the validations on the client side or http that provides secure communication?

3. It was mentioned that the planner does situation analysis, goal recommendation automatically. What methods are used to automate these processes? Does it manage all these operations happen without any human intervention?

4. It was mentioned in the paper that it uses more actions such as analyzer, recommender, guider which involves more messages or protocols to be transferred from client to the system. It may increase the traffic load on the network. What sort of measures is taken to control the traffic loads?

5. The system gives the recommended goals according to the former situations and achieved goals. But, the situations, and requirements may change dynamically. Does the system able to handle the dynamic requirements form a goal according to that?

6. It was mentioned in the paper that it the business model is designed using the policies and constraints. Whether these policies and constraints are pre-defined or the user needs to define the policies according to the business scenario?

Group 6:

1)There might be an increase in the congestion of the network with the use of many network protocols and policies to assist several procedures defined in the POEM. How the congestion in the network is reduced?
2) In the proposed system the author states that the policies are derived from an automated system. But what are the functions that are performed by the automated system to derive these?
3) The author explains all the functions and features provided by POEM in thoeritical manner but non functional parameters like reliability and efficiency etc are can not be estimated through a thoeritical system?

Critical Questions:

1)The author states that a "planner" uses "computational logic" to compose the processes by orchestrating services to get a desired goal based on the declared policies.Based on the input of current situation and goal situation.How does the planner understand the theoretical concepts as input? Current and goal situation are theoretical inputs,using this how does the planner system understand?

2)In automating the system to understand the user theoretical input(which aim for a business goal)the system uses "controlled language technique".How well does the "controlled language" technique transform the input into a desired business goal machine format?Since the correct input to the system is the basis for successful usage of policy oriented approach.

3)The author uses implementation of features by many theoretical concepts.How does the system realize these theoretical concepts and how much is it feasible in developing these concepts in practical way.The author does not support by any case study or results from some observation.

4)How are the "goals" expressed?In what format is the description given,so that the system can understand/perceive and specify the inconsistencies between policies and current situation.

Critical Questions:

1. Each organization has some policies, rules on constraints. According to the paper, by keeping these policies and the goal in mind, we should design the planner and the planner organizes the services in deriving the business processes. But in case if in the middle of the development of the business process we are supposed to change the policy or the goal based on the situation, how the system would be? What kind of adjustments are there to smoothen the process towards the Business Goal achievement?
2. From fig.5, the planner (User) takes the company policies and the Goal specifications then he will search the repository for appropriate services and web service specifications to build the system. This is very good approach till the services are available in the repository. If the services in the repository are not satisfying the policies then how and based on which factors the planner selects the services?
3. According to this paper, we follow the policies and by finding the goal we give these two to the system to develop the business process from starting point to the goal state. But how can we achieve the dynamicity as we are fixed to the policies?
4. Suppose we are developing the service in dynamic, then finding the goal should be done spontaneously and fast to proceed further. With in the short span of time how accurately can we assess the goal? In case of mistake the results would be miserable.

Critical Questions:
1.The paper stated that for integration of data, the languages like ‘XML’, ‘WSBPEL’, ‘PSL’, ‘WSDL’ are used. Apart from these,
are there any other languages that are used to provide the above functionality?
2. How is the integration of data and interoperability be achieved for large scale business goals?
3.The technical issues like ‘human-machine interaction’ has been stated. But the solution for these problems is not stated?

1) This paper suggests two approaches i.e. policy oriented approach and POEM's approach but could not specify which approach would be more efficient and which approach would give better result?
2)The POEM's approach talks about automatic generation of process design documentation, How is it achieved and how far the automatically generated document are correct is not been discussed in the paper?
3)The paper says that in order for the enterprise approach meet the goals , it needs to overcome certain challenges such as "semantic data integration", etc. who these challenges are met are not describe in paper?

1) What is the plan of action that is proposed to satisfy the goal policy for transforming from current situation to the goal situation?????

2) While in transformation to the enterprise physics domain the user refines the business goal into a goal the system can realize. Can the system can itself do this refining other than involving human at this stage?????

3) How is coordination achieved in between the analyzer, recommender(goal) , explainer and guide.????

1. In SOA the paper specifies some problems associated with it. But he does not explain any way to overcome them. It is possible that solving these problems would be easier compares to learn new approaches.
2. The paper suggests the planner to look up into all policies which impose constraints on the business process. What if the policies make it more difficult to develop the process?
3. The paper did not specify about how do developer get idea about the policies to be imposed while developing the process?

1. Differences on various Standard modeling language: WSBPEL(Oasis-open), Process Specification Language(PSL), WSDL
2. Do services really need to be decoupled. Can different services have a relationship in the SOA environment?
3. The situation analyzer is interesting. What is the underlying support for a situation analyzer? What is a possible solution for a situation analyzer?
