資訊生命週期管理示意圖

資訊生命週期管理是資訊管理領域的一種管理法，約在2002年、2003年開始興起。

資訊生命週期管理包含了政策、程序、實務、服務以及工具等，資訊的商務價值而拉齊、切合，最適切、成本效益的基礎建設，從資料建立到銷毀。資訊透過管理政策及服務水準，統合了應用程式、後設資料、資料等，以切合商務需求。

Information Lifecycle Management comprises the policies, processes, practices, services, and tools used to align the business value of information with the most appropriate and cost-effective infrastructure from the time information is created through its final disposition. Information is aligned with business requirements through management policies and service levels associated with applications, metadata, and data.

In the year 2004, attempts have been made by the Information Technology and Information Storage industries (SNIA association) to assign a new definition to Information Lifecycle Management (ILM).

到了2004年，由多數資訊技術業者、資訊儲存業者所組成的機構：儲存網路產業協會（Storage Networking Industry Association；SNIA），嘗試為ILM進行更清晰、具體的定義：

• Information Lifecycle Management is comprised of the policies, processes, practices, and tools used to align the business value of information with the most appropriate and cost effective IT infrastructure from the time information is conceived構想、設想 through its final disposition.最終配置 Information is aligned with business processes through management policies and service levels associated with applications, metadata, information, and data.

• 資訊生命週期管理，是結合政策、程序、實務、以及工具等要素，將這些用來切合資訊的商務目標價值，以及並以運用這些以滿足、達成運用這些以達成、切合商務價值

運用適切的、成本效益的資訊技術基礎建設

已想定的資訊 透過最終的配置

資訊切合商務程序，透過管理政策及服務水準，結合應用程式、後設資料、資訊、以及資料。

This is based on the desire to move information to less expensive means of storage and management based on its usage rather than evaluating its value to an organization and managing it accordingly. While there is a need to find a means to more effectively manage the vast quantities of information being generated electronically by organizations, the proposed IT practice is NOT by any means ILM, as it is classically known. ILM is as well part of the overall approach of ECM Enterprise content management.

Information Lifecycle Management (sometimes abbreviated ILM) is the practice of applying certain policies to the effective management of information throughout its useful life. This practice has been used by Records and Information Management (RIM) Professionals for over three decades and had its basis in the management of information in paper or other physical forms (microfilm, negatives, photographs, audio or video recordings and other assets).

ILM includes every phase of a "record" from its beginning to its end. And while it is generally applied to information that rises to the classic definition of a record (Records management), it applies to any and all informational assets. During its existence, information can become a record by being identified as documenting a business transaction or as satisfying a business need. And while most records are thought of as having a relationship to business, not all do. Much recorded information may not serve a business need of any sort, but still serves to document a critical point in history or to document an event. Examples of these are birth, death, medical/health and educational records.

功效

For the purposes of business records, there are five phases identified as being part of the lifecycle continuum. These are:

• 建立（或/及「接收」）
• 分發
• 使用
• 維護
• 清除

Creation and Receipt deals with records from their point of origination. This could include their creation by a member of an organization at varying levels or receipt of information from an external source. It includes correspondence, forms, reports, drawings, computer input/output, or other sources.

Distribution is the process of managing the information once it has been created or received. This includes both internal and external distribution, as information that leaves an organization becomes a record of a transaction with others.

Use takes place after information is distributed internally, and can generate business decisions, document further actions, or serve other purposes.

Maintenance is the management of information. This can include processes such as filing, retrieval and transfers. While the connotation of 'filing' presumes the placing of information in a prescribed container and leaving it there, there is much more involved. Filing is actually the process of arranging information in a predetermined sequence and creating a system to manage it for its useful existence within an organization. Failure to establish a sound method for filing information makes its retrieval and use nearly impossible. Transferring information refers to the process of responding to requests, retrieval from files and providing access to users authorized by the organization to have access to the information. While removed from the files, the information is tracked by the use of various processes to ensure it is returned and/or available to others who may need access to it.

Disposition is the practice of handling information that is less frequently accessed or has met its assigned retention periods. Less frequently accessed records may be considered for relocation to an 'inactive records facility' until they have met their assigned retention period. Retention periods are based on the creation of an organization-specific retention schedule, based on research of the regulatory, statutory and legal requirements for management of information for the industry in which the organization operates. Additional items to consider when establishing a retention period are any business needs that may exceed those requirements and consideration of the potential historic, intrinsic or enduring value of the information. If the information has met all of these needs and is no longer considered to be valuable, it should be disposed of by means appropriate for the content. This may include ensuring that others cannot obtain access to outdated or obsolete information as well as measures for protection privacy and confidentiality.

Long-term records are those that are identified to have a continuing value to an organization. Based on the period assigned in the retention schedule, these may be held for periods of 25 years or longer, or may even be assigned a retention period of "indefinite" or "permanent". The term "permanent" is used much less frequently outside of the Federal Government, as it is impossible to establish a requirement for such a retention period. There is a need to ensure records of a continuing value are managed using methods that ensure they remain persistently accessible for length of the time they are retained. While this is relatively easy to accomplishing with paper or microfilm based records by providing appropriate environmental conditions and adequate protection from potential hazards, it is less simple for electronic format records. There are unique concerns related to ensuring the format they are generated/captured in remains viable and the media they are stored on remains accessible. Media is subject to both degradation and obsolescence over its lifespan, and therefore, policies and procedures must be established for the periodic conversion and migration of information stored electronically to ensure it remains accessible for its required retention periods.
