Enterprise content management (ECM) is software that stores, versions and governs the millions of documents a company builds up, and keeps each one for as long as the rules require. It is also called document management, or a content services platform. Banks, insurers, governments, hospitals and manufacturers all use it.
A shared drive only stores files. ECM does four more things. First, it keeps every version of a document, so that anyone can see what changed and who changed it. Second, it attaches metadata to each document: facts about it, such as the customer number, the type of document and the date. This lets staff find a document by searching for those facts. Third, it controls who may open, change or delete each document. Fourth, it applies a retention rule to each type of document: how long it must be kept, and what happens at the end of that time.
Consider a life insurer in Mumbai with 40 lakh policies. Each policy has a file: the proposal form, the KYC documents, medical reports, and every change of address or nominee. When a customer signs a new proposal, the signed PDF arrives from the electronic signature system, and ECM files it under her policy number. Scanned forms from branches arrive with their fields already read by intelligent document processing. Only the claims team may open the medical reports. The insurance regulator, IRDAI, requires insurers to keep policy records for at least 10 years. The period counts from the end of the policy or from its last transaction, whichever is later. When that period passes, ECM deletes the file, and records the deletion.
There is one exception. If a policy is part of a court case, the legal team places a legal hold on its file. The file may not be deleted until the hold is lifted. Documents needed for the dispute are then collected with eDiscovery software.
Keeping documents for too long is also a risk. India's Digital Personal Data Protection (DPDP) Act says that, from 13 May 2027, personal data must not be kept once its purpose is over, unless another law requires it. So the retention rule protects the company in both directions: it keeps what the law requires, and deletes what it no longer needs.
ECM also supplies documents to other systems. A loan or a claim in case management software opens its documents from ECM. Law firms often use a specialised legal document management system instead. Aircraft makers keep their manuals in aircraft technical publications software.
