Software Systems:
The reliability metrics for the classes of software system is shown below.
| System | Reliability Metric | Suggested Value |
| Patient monitoring system | Availability | System must be unavailable for less than 20 minutes per month. |
| Word processor | Rate of Occurrence of Failure | Failures that result in loss of data should not occur more than once per 1200 hours of use... |

Consider the following scenario: you have been asked (as a software engineer) to create a hospital patient control application. Everything is explained to you up front, and the system demands a high degree of reliability. Which process model would you recommend for this kind of software, in your opinion? In addition to providing strong arguments to support your proposed process model, the explanation of the recommended process model should be accurate with the help of a visual and concise.
You are given the following scenarios. Identify the problem related to the software crisis for a given scenario. The problem can be Time Slippage, Missed Requirements, Cost Slippage, Failure at the customer Site.
Scenario A: Software for financial systems was delivered to the customer. The customer informed the development team to make the verification of biometric but the developers implement in another way.
Scenario B: A polar the satellite launch vehicle was scheduled for the launch on August 15th. The auto-pilot of the rocket to be delivered for the integration of the rocket on may 15th. The design and development of the software for the auto-pilot required more effort than planned and they need to engage extra resources for more implementation.
I need the answer for A and B, this is for software requirement engineering.
