What Is Application Lifecycle Management?

Software lifecycle management (Application Lifecycle Management ), referred to as ALM, refers to the entire process from the generation of software to maturity.

Life cycle is the objective law of the development of things, and software also has a life cycle. The early software life cycle often said that "software starts from planning and requirements, undergoes analysis and design, implementation, deployment, maintenance, and finally dies out." This is the first software life cycle model ---

Agile software development, also known as agile development , is a new type of technology that has attracted widespread attention since the 1990s.

In engineering and other related fields, acceptance testing refers to testing to confirm whether a system meets the design specifications or the requirements of the contract. It may include chemical, physical, or performance testing.

Acceptance testing in systems engineering may include black box testing before the system (such as a software system, many mechanical parts, or a batch of chemicals) is delivered.

Software developers often separate the acceptance tests performed by system developers from the acceptance tests performed by customers before accepting products. The latter is generally called user acceptance test, end-customer test, actual machine (acceptance) test, and on-site (acceptance) test.

Prior to the main test procedure, a smoke test is often used as an acceptance test at this stage. ^[2]
