Sebelumnya dibedakan antara Sistem-sistem informasi (SI) atau Information Systems (ISs) dengan Teknologi Informasi (TI atau Information Technology (IT) Berdasarkan konsep bahwa Informasi adalah setara dengan sumber-sumber serta dengan definisi tetang sistem informasi menurut Whitten cs. 2004. Menurut Turban cs., 2007, Data items refer to an elementary description of things, events, activities, and transaction that are recorded. Data items can be numeric, alphanumeric, figured, sounds, or images. Database consists of stored data items organized for retrieval. Information is data that have been organized so that they have meaning and value to the recipient. Knowledge consists of data and/or information that have been organized and processed to convey understanding, experience, accumulated learning, and expertise as they apply to a current problem or activity.

Whitten at al.(2004),System Analysis & Design methods,6th ed, McGrawHill, New York, NY. Sistem Informasi (SI) suatu aransemen dari (1)orang, (2)data, (3) proses dan(4) teknologigi informasi (TI) yang berinterkasi (4.1) mengumpulkan, (4.2) pemproses, (4.4) menyimpan, dan (4.5) menyediakansebagai keluaran informasi yang dibutuhkan untuk mendukung suatu organisasi. Menurut Turban cs., 2007. An information system (IS) as one that collect, processes, store, analyzes, and disseminate data and information for a specific purpose. The composition of information systems is usully the same: each containts hardware, software, data, procedures, and people. Another possible component of an information system is one or more smaller information systems, Information systems that contain smaller systems are typical of large companies. Sehingga bila membicarakan suatu Sistem Informasi (SI), sekaligus harus membicarakan Teknologi Informasi (TI). Tunggal M.
Menurut ITMRA = The Information Technology(IT) Management Reform Act of 1996, USA, INFORMATION TECHNOLGY – (A) The term information technology, with respect to executive agency means any equipment or interconnected system or subsystem of equipment, that is used in the automatic acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or reception of data or information by the executive agency. For purpose of the preceding sentence, equipment is used by an executive agency if the equipment is used by executive agency directly or is used by a contractor under a contract with the executive agency that (i) requires the used of such equipment, or (ii) required the used, to a significant extent, of such equipment in the performance of a service or the furnishing of a product Tunggal M.
The purpose of the Information Technology (IT) management function within the Office of the Chief Information Officer (OCIO) is to establish accountability for IT management in the a Department of ….. and to implement an IT Investment Management process for selecting, controlling, and evaluating IT investment. The Clinger Cohen Act 1996 calls for executive branch agencies to designate a Chief Information Officer who has overall responsibility for this management function. Di Indonesia belum ada semacam UU atau PP yang mengharuskan adanya OCIO dalam suatu Departemen. Tunggal M.
(B) The term information technology includes computer, ancillary equipment, software, firmware and similar procedures services (including support services), and related resources. Ditambah keterangan lagi: “The term information technology does not include any equipment that acquired by Federal contractor incidental to a Federal contract.” INFORMATION TECHNOLOGY SYSTEM An IT system is the process and procedure that utilizes IT resources to store, process, retrieve or transmit data of information using IT hardware and software. Automatic Data Processing (ADP) IT resources whose primary is the storage, retrieval, and processing data will be considered ADP. All hardware, software. Or services (including support services) resources associated with computer will be considered ADP. For IT management purposes, local area network (LANs), including the desktop computer, will be considered ADP System Tunggal M.
Telecommunications IT resources whose primary purpose is the transfer of information will be considered TC (Telecommunications). All hardware, software, or services (including support services) resource associated with telephone, pagers, radios, television, facsimiles or electronic mail will be considered TC. IT Architecture Information Technology Architecture means an integrated framework for evolving or maintaining existing information technology and acquiring new information technology to achieve the agency’s strategic goals and information resources management goals Tunggal M.
IT MANAGEMENT PHILOSOPHY The basic philosophy of the ITMRA for the management of IT includes the following concepts: • Each of ICD (Institutes, Centers and Divisions) should establish effective and efficient capital planning processes for selecting, managing, and evaluating the results of all of its major investments in IT systems • The IT management process should be integrated with the processes for making budget, financial, and program management decisions within the ICD investment. • The process should provide identifying, for a proposed investment, quantifiable measure for determining the net benefits and risks of the investment • The process should provide for evaluation of the work process to determine the best for it to be performed and the best way for it to be performed before the process is automated. • The process should provide the means for senior management personnel of th ICD to obtain timely information regarding the progress of an investment in an information system, including a system of milestones for measuring progress, on an independently verifiable basis, in term of cost, capability of the system to meet specified requirements, timeliness, and quality. • The acquisition of commercial off the shelf (COTS) IT hardware and software should be handled in the same manner as furniture, supplies and other types of commodity equipment and materials. • The amount of management activity expended i\on IT should be commensurate with the size and complexity of the IT activities .

Ada isitlah “sistem” yang perlu menjadi perhatian. Blanchard at al., 1998 mengadopsi definisi sistem dari The Random House Dictionary of English Language sebagai berikut. A system is an assemblage or combination of elements or parts forming a complex or unitary whole, such as a river system; any assemblage or set of correlated members, such as a system currency; an order and comprehensive assemblage of facts, principles, or doctrines in a particular field of knowledge or thought, such as a system philosophy; a coordinated body of methods or scheme or plan of procedure, such as a system of organization and management; any regular or special method of plan of procedure, such as a system of marking, numbering, or measuring Ada siklus hidup sistem dari mulai munculnya konsep sampai dengan sistem itu pensiun atau obsolete.

A Client/server architecturedivides networked computing units into two major catagories, clients and severs, all of wich are connected by local area networks and posibbly by private wide area networks. A client is a computer such as a PC or a workstation attached to a network, which used to access share network resource. A server is a machine that is attached to this same network and provides clients with these services. Servers are a database server that provides a large storage capacity and a communication server that provides connection to another network, to commercial databases, or to a powerful processor. In some client/server systems there are additional computing unit, referred to as middlewares. Other information Architecture: Electronic Data Interchange (EDI) and Legacy Systems Tunggal M.

Menurut Barrett, Richard dalam “Building Values-Driven Organization”, [2006] sehubungan dengan manusia keberhasilan perubahan sistem-keseluruhan mempunyai tiga pra syarat. • Para pimpinan kelompok seyogyanya menjalankan proses perubahan; mereka perlu punya komitmen, dan menjadi contoh-contoh dalam hal visi, misi, nilai-nilai dan perilaku – harus “Walk the talk” -. Perubahan bermula dengan transformasi personal kepemimpinan kelompok. • Visi, misi dan nilai-nilai termasuk perilaku pendukungnya seyogyanya berpengaruh terhadap semua pembuat-keputusan. Nilai-nilai dan perilaku seyogyanya mereflaksikan setiap aspek struktur, sistem-sistem dan proses-proses kelompok. Setiap aspek tentang apa yang dilaksanakan perlu sejalan dengan visi, misi, nilai-nilai dan perilaku. • Mempertahankan kinerja tinggi, budaya seyogyanya teramati secara komprehensip melalui pengukuran individu dan kolektif dari indikator kinerja “kausal” (nilai dan perilaku). Sebaiknya tidak diperlukan “early-warning system” yang mengukur entropi kultural atau suatu pnurunan ketahanan kultural. Tunggal M.
