Integrating Knowledge Management and Business Intelligence Processes for Empowering Government Business Organizations

Emergence of information technologies has transformed the way business marketing is done and how business enterprises are managing the resources and information. Trend of globalization has induced the fierce competitiveness among business enterprises within domestic and international markets. The major quest for the technologies is not limited to strategic value of an organization but also empower the organization work context by utilizing its resources. Knowledge management has emerged as the latest techno-management trend for improving the work process and creating value for business organization operations. Knowledge management offers various techno-managerial implications to business organization for strategic development. However, there are scarce evidences on business intelligence, strategic management decision support related to business organization adopting these offerings. Major objective of Business Intelligence is to extract the information and find the hidden knowledge from all sources of data. Business Intelligence offers to make decision for enhancement of any organizations goal.  The broad overview of research articulates an understanding of government based organizations about the adoption of Knowledge management based Business Intelligence solutions and its challenges. Data mining is playing a key role in Knowledge Management based systems for business organizations and its implication lies in the implementation of data mining algorithm for exploring the huge amount of data, which determines the pure knowledge.
Majority of the government organizational data remains in either unstructured form such as raw form of data (i.e. internal or external document) or with its employees in the form of experience. Knowledge management process deals with extraction of both tacit and explicit knowledge of organization for improving the performance of organization. However Business Intelligence (BI) on the other hand gained its importance with constant enhancement in technologies and tools for extracting the hidden knowledge and patterns. Hence it can be argued that both Business Intelligence and Knowledge Management are complimentary to each other for extracting and managing the knowledge. Thus it’s very imperative for government organizations to have an integration of both Knowledge Management (KM) and Business Intelligence (BI) processes for enhancing the performance of the organization with respect to make organization decision for competitive environment and utilizing the organizational tacit knowledge.
The paper focuses on how BI and KM integration affect the government business organization while discussing its implementation challenges. The paper tries to analyze the correlation between Knowledge Management and Business Intelligence and exploring a road map for data mining based framework for Knowledge Management focusing government based organizations. Current situation of knowledge management strategic decision making and role of knowledge must need to be addressed before proposing any framework for government organization. Paper provides a detailed extensive literature review which aims to describe the basics of Knowledge Management based systems and integrating Business Intelligence with Knowledge Management. Study will draw a distinction between individual and organizational knowledge as well as whether knowledge is playing a key role in strategic development or not?

INTRODUCTION

In the era of knowledge and technical innovation, it has been widely accepted that intangible assets of any business organization will be key to its success. Knowledge is supposed to be most important asset of any business organization, which has the largest influence on competitiveness, strategic development, and growth. Every organization has individual and organizational knowledge either in the form of raw data or information. Raw data or information retains within organization in the form of implicit knowledge and with limited resources. These information or raw data needs to be processed to acquire knowledge through the use of knowledge management & data mining approach.  Further knowledge can be made accessible to all through knowledge management process. Several environmental factors around which each business operates are: globalization, fierce competition, changes in organization structure, growth of information technology, and advent of knowledge management process. Thus, emergence of Knowledge Management discipline has changed the direction of business strategic planning. In the context of business organization, knowledge management is used to acquire the knowledge and experiences it for strategic development. Reuse of preciously acquired knowledge can be beneficial for preventing past failure and used as a guideline for fixing recurrent issues. It has been claimed that in business enterprise the knowledge not only embedded to document and repositories but also with enterprise routine, process, and practices.
Thus, knowledge is recognizing itself as one of the most important assets of any organization. Knowledge is acquired through the processing of available data of organization using data mining approaches. Data mining is a tool for processing the data to find out the relationship within the data that can be beneficial for the user. Data mining has the potential to use is as a powerful tool for the business intelligence but yet not fully recognized.  With the proliferation of the new technologies data mining has experienced an exponential growth and became an integral part of Knowledge Management system. Data mining algorithms are applied to explore the underlying data of business organization and after processing it determines the effectiveness of knowledge.  
The major focus of this paper is role of Knowledge Management and Business Intelligence Processes for government based organization. Government based organizations means functional government agencies, various departments who perform public services. The paper aims to find how government organization managers adopt both KM and BI processes in public sector. Study aims to find out the interrelationship between Knowledge Management and Business Intelligence, and utilize it for strategic development and decision making. 
In government based organization, there are extensive amount of data which is used within organization for business policy management, organization decision making, and growth & development of organization. Since environment changes in any organization drastically, thus any change in the data also reflects the change in the system. The change can be related to various categories such as:
  1. Change in the quantity of data, it means with the growth in any organization amount of data will be increased substantially.
  2. With the increased amount of data, the correlation between data also changes it means the relationship between application system also changed.
Therefore these organization need to understand the data, process and mine the data to acquire knowledge from the large amount of data and extract intact and practical knowledge from random, vague, incomplete, and huge amount of data. This extracted knowledge can be utilized for decision making business intelligence. Primarily in the Knowledge management process, knowledge discovery process needs to apply data mining algorithms. Varieties of algorithms are available in data mining such as genetic algorithm, decision making, neural network, and fuzzy logic. 

This paper is based on government based organizations, in which Knowledge Management process needs to implement for strategic development and decision making, and organizational development for the social and economical growth of the organization as well as improve its competitiveness in the era of globalization. Research aims to monitor, explore the evolution of business intelligence and Knowledge management implementation as a means to improve the work practice of business organization. The fundamental purpose of the paper is to discuss the need of integrating KM and BI for exploiting structured & unstructured raw data, implicit information of the organization and its challenges. This will helpful for creating an integrated knowledge based decision support system framework for government based organization which integrates both Business Intelligence and Knowledge management.

LITERATURE REVIEW

Most researchers and practitioners agreed on the practical implication of knowledge as one of the important assets of any organization. Knowledge Management and Business Intelligence are the two major areas of researchers concern. Knowledge management is a tool for empowering the knowledge within the organization, and useful for decision making. However, Business Intelligence has affected the business world the most for transforming the raw data into knowledge. This can be used for prediction analysis. A dearth research has been performed to explore Knowledge Management, Business Intelligence and its applicability within various application domains.
Authors have analyzed that Business intelligence is the broad categorization of applications of processing large amount of data for any organization to make prediction analysis. Operations such as OLAP (online analytical processing), data warehousing, data reporting, and business rule modeling are used by Business Intelligence. However, Knowledge Management is the process of knowledge acquiring and creation, knowledge sharing and dissemination and knowledge application. Authors have suggested that both Business Intelligence and Knowledge management are influenced by environment of the organization. The success ration of Knowledge Management is directly proportional to employee attitude. Thus, there is a need of common platform for the organization where both employer and employee can share the knowledge.
Author has proposed a scheme for transforming Knowledge Management into Business Intelligence. Author has also briefed certain parameters for implementing them to organization for a common workflow. However, the new or new solution cannot be added directly for the adoption purpose. Tacit knowledge plays a vital role in all the phases of any newly innovative process and implementation of tacit Knowledge Management and can be helpful for handling new problems.
Author has proposed a memory model for linking individual knowledge to knowledge managements. However, the practical implication of this model is very weak. Outcome of knowledge management process over business intelligence and organizational performance with the help of influential variable. Therefore, it can be concluded that any knowledge management based system is a handy tool for achieving completive advantages. Some of the attempts have been done by the authors to integrate knowledge management for real time Business Intelligence and its benefits. Focused on tacit knowledge and explained it as a vital component for organization. However, management of tacit knowledge is a challenging task. Thus, there is the need of a common framework where tacit knowledge can be categorized into various degrees.
Both knowledge management and business intelligences are different from each other in terms of common foundation. Thus the interrelation between knowledge management and business intelligence needs to be explored. Simply an insight can be concluded that business intelligence is used for transforming data to knowledge, whereas Knowledge Management can be used as a tool for knowledge acquisition, knowledge sharing and to create new knowledge.
The advantages and disadvantages of Knowledge Management, Business Intelligence and further proposed KMBI framework for the integration of Knowledge Management and Business Intelligence. This framework consist of three different layers namely data, presentation, and function integration.
With reference to various contexts, articles, paper reviewed, and application of Knowledge management it is analyzed that data mining is widely used toll for Knowledge Management and Business Intelligence both. Since both Knowledge Management and Business Intelligence are correlated and can be integrated for the better performance of an organization. Both are complimentary of each other, thus both can result in more effectiveness for government based business organization.

MANAGING THE KNOWLEDGE

Knowledge is defined as the mix frame of facts, expectation, skills, and combination of relevant information collected through experience, study, and reasoning, for enhancing the ability of decision making and evaluating the right context. However data, information and knowledge are the key terms which are the set member of knowledge management and may used interchangeably. Several arguments are made by the researchers about these terms, and defined as:
Data can refer to unprocessed, unstructured collections of random facts; Information refers to structured and processed data having some sense to the user, whereas Knowledge refers to the most refined and highly useful data for decision making and problem solving.
Various researchers have proposed several classification methods for classifying the knowledge. The classification of knowledge is helpful to the organizations for processing and managing their various available knowledge resources. Most widely accepted classification of knowledge is: Explicit and Tacit knowledge.
Explicit knowledge contains the knowledge, which has been already processed in the form of visual, text, diagrams, tables, manuals, and specific documents. Acquisition of explicit knowledge is easy, since it is in the form of table, manuals, and document; so as easy to manage too. In case of government based business organization explicit knowledge may contain such as business specification, product specification, contracts, and customer data.
However, tacit knowledge refers to most valuable knowledge as it is in the form of experience, skills, and communications. It remains as understanding of people and expressed in the form of language. Tacit knowledge is very beneficial to find best solutions and managing the organization on the basis of previously known knowledge. The only issue with tacit knowledge is, it cannot be articulated as it remains in the form of experience and skills. Since, tacit knowledge is personal, as it is retained in mind in the form of experience, skill and perceptions, hence very tough to manage, share and articulate it. In case of government based organization tacit knowledge may include work such as process, project dealing, problem solving, and expert opinions.
Some authors have proposed that some part of the tacit knowledge can be acquired and converted into explicit knowledge. Several authors have proposed an hierarchy to have an understanding of data, information and knowledge types as shown in figure 1.

LITERATURE REVIEW

Information Technology

Information technology has an important role in most of the business process reengineering. Speed, information processing capabilities, and connectivity of computer and internet technology can improve and increase the business process efficiently. Information technology is not limited to computer technology (hardware and software set of tools) that is used to process and store information, but that includes information technology to transmit information.

Theory of Reason Action (TRA)

Theory of Reason Action was introduced by Fishbein and Ajzen (1975), which helps researchers to understand and predict the attitudes and behavior of individuals. TRA has successfully predicted and explained the behavior of different areas of study. The TRA theory is most often used as a theoretical model of the information system. Individual's performance of a particular behavior is determined by the purpose for running behaviors, and the destination is determined by attitude and subjective norm. Several specific factors in determining the behavior of technology acceptance are: behavioral intention to define the behavior, if behavioral intention combined with the attitude and subjective norm.

Cobit 4.1: A Maturity Level Framework For Measurement of Information System Performance

Universitas Respati Yogyakarta requires methods and structured approach in its evaluation, especially in academic departments. This should to be done to assess the fit between institutional objectives with management that has been applied. COBIT is a framework used to assess, measure and control the performance of institutions in the management of IS/IT. COBIT is also accepted and harmonized by its users, because the framework is built from the goal, rules and institutional policy where all processes are analyzed by looking at the alignment between the objectives to be achieved by the procedures/policies implemented by the institution. In this study the author uses COBIT (Control Objectives for Information and Related Technology) version 4.1 on the domain Planning Organization (PO). The results of the study conducted performance measurements are made in the form of academic information system analysis, mapping the level of maturity and recommendation for Universitas Respati Yogyakarta, which is expected to be a management model for other institutions.

INTRODUCTION

Some companies do not hesitate to invest their share in the field of Information Technology (IT), although the investments make enormous drain on the budget. This is done as an effort to get the convenience and benefits of the use of IT, which is expected to help the performance of the company to conduct a competitive business strategy. However it turns out, the investment made by the outcome often is not generated. Assessment and evaluation of investments that have been issued for the implementation of IT is proper to be considered. Based on some research explained that the company has begun to realize and start doing performance measurement and evaluation.
To make the use of performance measurement and management of IT, then The IT Governance Institute (ITGI) as an institution conducting the IT governance arrangements that have standardized tools or frameworks is widely used in the world including COBIT, ITIL, COSO, ISO, and so on. COBIT is a reference method/framework for measurement and control of information technology. COBIT framework is a standard that is considered the most complete and thorough as IT audit framework as developed based on the rules/procedures of internal company/institution where COBIT is used, so the time will be measured in accordance with the conditions, rules, procedures and norms that work in the company. COBIT has also been developed on an ongoing basis by professional NGOs auditors spread throughout much of the country, where in each state builts a relationship that can manage these professionals.
Performance measurement in academic information system at the Universitas Respati Yogyakarta that utilizes IT as a means of supporting the process is expected to support the management of the education process. For example at the beginning of the selection for new students, the learning process which is done, lectures supporting components such as the method used, the curriculum and other provisions such as faculty, students, facilities, other facilities until the graduation of students who need to be evaluated in order to produce quality and good service and competitive education.

Information Technology Architecture

The Information Technology Architecture (ITA) is described through a set of views, each from the perspective of a different stakeholder. An individual view captures items meaningful to the stakeholders as elements and their interrelationships expressed in a standard form, the structure of the view, and the view’s correlation with other views. Typically, groups within the organization possess a mixture of Commercial Off-The-Shelf (COTS), frameworks and custom-developed legacy applications as well as data stored in databases and directories. In such an environment, functionality and data embedded in one application cannot be easily merged with functionality and data provided by another. Such an endeavor usually requires the creation of a yet another separate application. Further, each of these applications relies on a proprietary client for user interaction.


COBIT Framework

COBIT Framework is an IT governance framework aimed at management, IT service staff, department control, and audit function more critical to the business process owner. COBIT Framework as a framework for the management needs for measurement and control of information technology provides the tools to measure the ability of information technology that will continue to be developed. COBIT framework is created to serve as a reference to exercise control over information technology and can ensure confidenciality, integrity and availability of the data. The results obtained from the IT Governance is used as a reference or management guidelines, one of which is COBIT which has a measuring tool such as maturity models, CSF, KGI and KPI. COBIT has a measurement indicator management of information technology in business processes.
From the results obtained it appears that the institution has a different level for each PO domain. In general, institution occupies level 3, which means that the institution has procedures in management, has been communicated and documented for each element in the institution. However, the implementation is still highly dependent on existing human resources willing to perform the procedure or not. That existing procedures are still limited to the formalization of implementation available, and management needs to improve planning and organizing. The discrepancy between the technical implementation of management policies with existing will be reduced by the control and measurement refers to guidelines such as COBIT Framework KPI, KGI, CSR and maturity models in COBIT Framework for monitoring ranging from policy-setting; monitoring is being conducted at the time, until the goal is achieved.

Dell’s Supply Chain
Dell’s supply chain works as follows. After a customer places an order, either by phone or through the Internet on www.dell.com, Dell processes the order through financial evaluation (credit checking) and configuration evaluations (checking the feasibility of a specific technical configuration), which takes two to three days, after which it sends the order to one of its manufacturing plants in Austin, Texas. These plants can build, test, and package the product in about eight hours. The general rule for production is first in, first out, and Dell typically plans to ship all orders no later than five days after receipt. There are, however, some exceptions. For example, Dell may manipulate the schedule when there is a need to replace defective units or when facing large customers with specific service-level agreements (who have nonstandard quoted manufacturing lead times) for their orders.
In most cases, Dell has significantly less time to respond to customers than it takes to transport components from its suppliers to its assembly plants. Many of the suppliers are located in Southeast Asia and their transportation times to Austin range from seven days for air shipments to upwards of 30 days by water and ground. To compensate for long lead times and buffer against demand variability, Dell requires its suppliers to keep inventory on hand in the Austin revolvers (for “revolving” inventory).

PENDEKATAN MODEL INFORMATION TECHNOLOGY INFRASTRUCTURE LIBRARY (ITIL) DALAM REKAYASA SISTEM INFORMASI UNTUK PENCAPAIAN IT-GOVERNANCE

INFORMATION TECHNOLOGY INFRASTRUCTURE LIBRARY

Author: Herison Surbakti

Suatu organisasi hendaknya menyiapkan blueprint Teknologi Informasi yang akan dipergunakan untuk mendukung proses pengolahan data  sebelum membangun dan mengimplementasikannya, yang pada akhirnya akan menghasilkan suatu informasi yang dibutuhkan sebagai bahan pertimbangan pengambilan keputusan dalam menentukan kebijakan organisasi pada masa mendatang.
Hampir semua organisasi membutuhkan teknologi informasi untuk mendukung kegiatan organisasi, namun tidak semua organisasi mempunyai blueprint Teknologi Informasi yang baik, sehingga akan mengalami kesulitan untuk mengembangkan sistem/apliksi dibidang teknologi yang dimiliki.
Kesulitan dalam membangun blueprint dan roadmap implementasi ditimbulkan akibat dari tidak adanya standar arsitektur sistem, tools pengembangan, database management system (DBMS) dan manajemen dokumen sistem. Desain perangkat lunak sangat bergantung pada struktur organisasi perusahaan karena berhubungan dengan pemeliharaan, perbaikan sistem pengujian, integrasi sistem dan pengembangan sistem yang akan dimulai dari awal, bukan melanjutkan sistem yang sudah ada.
