Are standard operating procedures (SOPs) valued across industries?

Definitely yes, especially in large scale industries. without SOPs everyone will do what they think is right from their point of view and this will always conflict with the company's vision and the way of handling things. in my opinion - All companies even small to medium scale companies should implement SOPs on the first year of business, SOPs must be well documented/updated and handed to every new recruit from day one.
Based on my experience with my current employer and since we were late in establishing SOP's for every department, we had many interdepartmental conflicts and resistance to any new changes in policy.

Yes very important especially in Healthcare

We leveraged SOP's to help with sharing of data across legal affiliates as a governance/audit tool.  Ex -The SOP would dictate the stakeholders as well as the process and controls that governed when data was being shared between affiliates.  The SOP defines what data was being shared, for what purpose and what the permissible uses, who was able to access, what access controls were in place, the process for sharing the data, as well as how data was to be returned or deleted upon the end of the service agreement.  This created awareness and accountability to the senders and receivers to ensure others were not able to access or use the shared data outside of the SOP defined case. SOP signed by both parties acted as a contract that was reviewed annually to ensure compliance.

SOPs are a must for the certification journey, aiming at better collaboration and narrowing the communication gap between IT and business, maturing in IT & IS management, and ultimately yielding to increased revenue.

Yes, SOPs (Standard Operating Procedures) are valued across industries. I am associated with four different industry verticals in my current work assignment. We have developed SOPs for most of the processes. In construction Hospitality and Facility management, we have SOPs for all major activities/process. SOPs help in making the process independant of the employees, helps in training as new appointees will have all the required information to work easily available in one place. SOPs make operations simpler and easy to review/diagnose.
