Waht is the difference between authorization and access control? Access control specifies what a user can do, and authorization
spayn [35]
<h2>Answer:</h2>

Authorization specifies what a user can do, and access control enforces what a user can do.

<h2>Explanation:</h2>

Authorization is simply granting access to an authenticated user of an application. It specifies what a user can and/or cannot do. For example, for a user to access their banking details in an online banking service, they have to be authorized by first authenticating them to prove their identity. Another example is in an organizational system where some users (normally called admins) can access certain database info whereas some other users (normally called the regular users) cannot.

Access control is used to enforce the policies dictated by authorization. In other words, access control enforces the policy of what a user can and/or cannot do. Access control makes authorization possible. It is sometimes called privileges or permissions. For example, the <em>security tab </em>in the operating system of Windows, allow to set access privileges for certain files and/or folders. Another example is in an organizational system where some files on the organization's server are configured in such a way that access to it is restricted and dependent on some further authorization.

Which of the following is a basic principle of improvement?
lesya [120]

From the given the statement, "every system is perfectly designed to get the results it gets" is a basic principle of improvement.

Option B

<u>Explanation:</u>

The improvement activity begins with the quote ‘every system is perfectly designed to get the results it gets’, by W. Edwards Deming; The quote states both the unintended and intended effects are designed into our systems.

For example: Healthcare in the UK has been perfectly designed to lower the waiting times to 18 weeks for various procedures over last twelve years. Reflecting on Safer Patients Initiative (SPI), this can be true to improvement systems: every improvement system is perfectly designed to get the results its gets and SPI is a case in point.

The leading improvements that need to be designed into our improvement systems:

  • Improvement activity needs to be built on strong foundations
  • Greater engagement with people’s intrinsic motivation
  • Embrace a wider set of methods
  • Greater understanding of how systems and processes outside direct clinical care contribute to safety and quality.

So, it can be concluded that the line given by W. Edwards Deming tends to be the principle of improvement.
