Csm

CSM is an acronym that can refer to several terms across different domains. Its meaning is dependent on context, and the same letters can denote roles, objects, titles, or certifications in military, aerospace, computing, and business practice.

In military contexts, CSM most commonly stands for Command Sergeant Major, a senior noncommissioned officer rank found in the United States Army and other armed forces. The role typically involves senior enlisted leadership, advising commanders, and maintaining discipline and welfare of soldiers.

In aerospace, CSM stands for Command and Service Module, the two-part spacecraft used by NASA's Apollo program. The Command Module housed the crew during reentry, while the Service Module provided propulsion, power, and life-support systems until it was jettisoned before reentry.

In computing and IT, CSM has several meanings. It can refer to Compatibility Support Module in UEFI firmware, which enables legacy operating systems and hardware to boot on modern systems. It is also used for business software roles such as Customer Service Management or Customer Success Manager, terms associated with managing customer relationships and service delivery.

Another common use is Certified Scrum Master, a professional certification in Agile project management awarded by the Scrum Alliance. Individuals with this credential are expected to facilitate Scrum practices, guide teams, and promote iterative development and continuous improvement.
