The lack of identify services mechanism which is related to the development
of information systems could be impact in wasting time, over budget and can
not adapt to the changing environment. This phenomenon is happened by the
belief that lack of capturing user requirement. This is due to consider the
business environment is always running normally. In fact, the development
of the system needs a way to anticipate the business environment that
unpredictable changes.Therefore, the phenomenon on the need for modeling
services can able to respond to the changing needs of users still have a
chancein this study. It explores modeling services to synergize SOA and
BPM.Several previous studies generally use a business driven approach,
technical partially driven to develop the service modeling. This leads to the
question of how a service should be modeled so that it can be applied in
different contexts and business processes also. It is support user needs in
diversity and heterogeneous system environments. This Conditions occurs in
corporate university. The case studies in this research is a Learning
Management System (LMS) in Academic Enterprise System (EAS). The
research stages are: (1) Analysis of Synergy in SOA and BPM, (2) Analysis
of User Experience in LMS Academic Enterprise System (L-EAS),
(3) Analysis of Modeling Framework, (4) Proposed Framework that aligning
SOA and BPM. The result of this study is proposed system framework based
on services to increase the flexibility of information systems at LMS
Academic Enterprise System (L-EAS).

1. INTRODUCTION
SOA (Service Oriented Architecture) appears to offer adaptive and reactive to the environment as
well as offering a solution to the complexity of business processes, systems and technology [1]. Service
diversity in general can be viewed differently by business experts and IT experts, as well as the perspective
of the process bisnis.fenomena this is supported by the belief that the absence of changes in user
requirements for a services [2]. This is due to consider the business environment is always running normally.
In fact, the development of the system needs a way to anticipate the business environment unpredictable
changes [3].
SOA architecture embraces the bottom-up approach while BPM maintains a top-down process. If
implemented in an enterprise [4] SOA without involving BPM, reusable and reliable service that can be
created, remain unable to increase the speed even further [5]. BPM is a dynamic process optimization and

adaptation process, whereas SOA is a mechanism to create an agile service and provide a means to regulate
the services [6].
2. STATE OF THE ART
User experience is the feeling experienced before, during, and after someone using a service or
system [7]. These flavors include emotions, beliefs, preferences, cognitive impression, and many other
factors.There are four factors that play a role in the user experience [8]: (1) Branding, which covers all
elements relating to the design and the visual of a website, (2) Usability, ease of use of the website to the
user. Navigation and accessibility are covered here, (3) Functionality, namely the technological aspects of the
product or application (4) Content, or the content of such websites. It is just as important as a well-designed
interface. Usability is the ability of a software / website to offer its interface with friendly to users. Usability
of a site will have a direct effect to the experience of visitors to the site. Therefore, usability is an important
factor in the design of a site. Therefore, the phenomenon on the need for modeling services are able to
respond to the changing needs of users still have a chance to study. The process to minimize failure in
requirement analysis using business process model and goal model has described in [9]. Relate to [10], it
describe the development of software product line (SPL). On the other hand, according to [11], the software
complexity could be measure with proposed framework. However, the previous study is not addressed the
improvement of information system application in dynamic environment. The challenge is how to aligning
business domain and technical domain in information system development phase.
3. RESEARCH METHOD
The purpose of this research is (1) Make Modelling Services for the service provider to synergize
SOA and BPM (2) Creating a mechanism that can provide services to diverse user needs. The benefits of this
research are (1) Assist developers in developing systems of enterprise systems. (2) Service providers can
provide services that can respond to changes in the business environment to be used by a service consumer.
This study is one study that explores modeling services to synergize SOA and BPM. Several previous studies
generally use a business driven approach, technical partially driven to develop the service modeling. This
leads to the question of how a service should be modeled so that it can be applied in different contexts
different business processes and business pressures are quick to support user needs are diverse and
heterogeneous system environments. But so far, have not seen any research service modeling using business
driven approach and technical driven to accommodate the needs of a diverse and dynamic user and
heterogeneous system environments.The benefits of this research can contribute in terms of:
Service Service Provider can provide and manage services that are used by a service consumer and also
can improve SLA (Service Level Agreement).
Research Method consists of four steps, such as:
a. Analysis of Synergy of SOA and Business Process Management (BPM): This stage aims to get state of
the art research related synergies SOA & BPM. In this stage, we explore literature that considers the
stages of comparison, contrast, analysis, and synthesis. The results of this phase is the state of the art
research.
b. Analysis of User Experience Forum LMS Academic Enterprise System (L-EAS): This stage is done by
spreading a brief questionnaire related to user experience using Forum in LMS Academic Enterprise
System (L-EAS)The purpose of this phase is to determine the user experience on LMS Academic
Enterprise System (L-EAS).
c. Analysis Modeling of Framework that Synergies SOA & Business Process Management (BPM): This
stage will use the conceptual literature which synergize SOA & BPM. The results of this phase is the
mapping of the system environment and defining the system fleksbilitas.
d. Proposed Framework that Synergy of SOA and Business Process Management (BPM): Services inamount
of variety, will be combined and synergy in order to establish a service-based system. It aims to simplify
management. This stage will focus on techniques to conduct merger and synergy with the use of
orchestration and choreography. The Results in this stage is a framework that work to combine and
synergize services.
4. RESULTS AND ANALYSIS
Environmental conditions that have the characteristics of corporate university, has a specific
uniqueness. The LMS in the corporate university requires a high adaptability to changing. According to the
previous research that has been mentioned on the above analysis, it shown that so far no studies for

evaluating the Synergy between BPM with SOA. It can be represented and shown that SOA can have ability
to reusable business services for the corporate university. This study will take a case study on the LMS
Academic Enterprise System (L-EAS). Despite of it, the changes that occurs in this conditions are not
predicted, and it always happened in the business domain and business function (functional area). Changes
that occurs in both of it, will caused the effect of organizational changes in the scope of information systems.
The impact in further changes is the information requirements which is derived from much of application.
Relate to it, the changing information needs, will also influence the changing in software and infrastructure
existing. Academic Enterprise System (EAS) is an enterprise system that used higher education institutions in
managing and optimizing existing resources. EAS can cope with changes in policy and provide flexibility in
responding to such changes. EAS can provide task and business processes that can be be reused. EAS
provides software and business processes that have commonality, variability and specific in software
features. If seen from the types of applications used by higher education institutions that have the
characteristics of corporate university, it shown the intersection on business processes. These conditions
allow the Policy that are common, but there are also specific to each business unit in corporate university.
Therefore, it allows a business process can be used for sharing (together). Therefore, if depicted in
the Venn diagram will be described in Figure 1.

Definitions and Descriptions Flexibility Academic Enterprise System (EAS), EAS has the following
definition:
a. An organization is a group of non-consecutive collection of one or more AF (Functional Area):
Org = {AF1 , AF2, ……..AFn }
b. AF is a functional representation of a functional-owned by an organization and is defined as a set that
consists of one or more Business Process (PB).
AF = {PB1 , PB2, ……..PBn }
c. WS (Work System) is one or part of the AF system is managed by an organization and consists of a
minimum of a PB. In practice, the PB delegated to AF-AF, where PB is a joint member (wedge) from WS
and AF.

WS = { PB1 , PB2, ……..PBn }
d. The intersection between the two Functional Areas, AF1 and AF2 occur if one or more business processes
related to AF1 which is also associated with AF2 (the same WS).
AF1 ∩ AF2 = { PB |PB € AF1 ^ PB € AF2 ^ PB € WS ^ PB € AF1 ^ PB € AF2 }
e. Business Processes can be decomposed into Business Processes (PB) more specific.
We proposed Framework system which is consists of software components that integrated one with
each other. The software components are flexible and can plug n play according to user needs. Within the
framework of this system, there is a mechanism that serves to accommodate the reusability and
interoperability. This framework consists of four main layers, namely: (1) Common application layer,
(2) Authentication Layer, (3) ESB (Enterprise Service Bus) layer, and (4) Specific application layer. The
function of common application Layer is to handle variaty in common function blocks and applications. ESB
(Enterprise Service Bus) and serves to manage communication between applications. Specific Application
Layer functions to handle specific applications that exist in every organization. The proposed framework of
synergy SOA & BPM system shown in Figure 2.
Figure 2. Proposed framework
According to Framework Mechanism in Figure 2 above, it proposed a framework that synergize
SOA & BPM to accommodate the needs of LMS Academic Enterprise System (L-EAS) in corporate
university. This framework consists of a layer of SOA and BPM Layer. Grouping SOA and BPM layer to
accommodate the application of common and specific applications in the corporate university which has
multiple business entities
5. CONCLUSION
The conclusions of this research is the changes that occur in conditions which is not predicted in the
business domain and business function (functional area). Changes that occur in both will cause the effect of
organizational changes in the scope of information systems. Further changes will affect the information
requirements. The changing information needs, will also influence the change software and infrastructure.
LMS Academic Enterprise System (L-EAS is an enterprise system that used in higher education institutions
for managing and optimizing existing resources. It can provide task and business processes that can be
reused. It also provides software and business processes which have commonality and variability layer. The
types of applications used by higher education institutions are having characteristics in corporate university.

It shown the intersection on business processes. These conditions allowing common policy, but there are also
specific to each business unit in corporate university. Therefore, it allows a business process can be used for
sharing. In order to accommodate these conditions, the proposed Framework consists of software
components are integrated with each other. The software components are flexible and can plug n play
according to user needs. Within the framework of this system, there is a mechanism that serves to
accommodate the reusability and interoperability
