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.

Siklus Informasi

Untuk memperoleh informasi yang bermanfaat bagi penerimanya, perlu dijelaskan siklus yang terjadi atau dibutuhkan dalam menghasilkan informasi. Pertama-tama data dimasukkan ke dalam model yang umumnya memiliki urutan proses tertentu dan pasti, setelah diproses akan dihasilkan informasi tertentu yang bermanfaat bagi penerima (level management) sebagai dasar dalam membuat suatu keputusan atau melakukan tindakan tertentu. Dari keputusan atau tindakan tersebut akan menghasilkan atau diperoleh kejadian-kejadian tertentu yang akan digunakan kembali sebagai data yang nantinya akan dimasukkan ke dalam model (proses), begitu seterusnya. Dengan demikian akan membentuk suatu siklus informasi (information cycle )atau siklus pengolahan data (data processing cycles),

JUST IN TIME MANUFACTURING

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.
