Chapter 10, Problem 10.7E
Program Plan Intro
Dependable Process:
Dependable Process has a defined process model that is used to drive the software production process where data must be collected during the process that proves that the development team has followed the process as defined in the process model.

Consider the following illustration: You have been charged as a software engineer with creating
a hospital patient control application. Everything is explained immediately, and a high degree of
reliability is required of the system. Which process model would you recommend for this kind of
software, in your opinion? In addition to providing persuasive arguments in favor of your chosen
process model, its explanation should be accurate, concise, and supported with an image.
a) Suppose a given system allows for indefinite postponementof certain entities. How would you as a systems designer provide ameans for preventing indefinite postponement?
b) A system requires that arriving processes must wait forservice if the needed resource is busy. The system does not use"aging" to elevate the priorities of waiting processes to preventindefinite postponement. What other means might the system use toprevent indefinite postponement?

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.

- Which perspectives should software-intensive system models consider?arrow_forwardThis question is from the subject Software Engineering Concepts Case Study: A software house named OpenCode won a scalable project with very large scope. The project can be easily visualized in components. In addition, the fast development of the software is desirable. The HolyByte has not sufficient staffing to develop such a large and scalable project in shorter time span. However, the software house has developed numerous similar projects. Thus, OpenCode not only has the technical expertise but it also has rich library of the similar solutions already developed. 1) Name of the Process Model? 2) Reason of the Selection?arrow_forward4. Using the module hierarchy given below, show the orders of module integration for the top- down and bottom-up integration approaches. Estimate the number of stubs and drivers needed for each approach. Specify the integration testing activities that can be done in parallel, assuming you have three SIT engineers. Based on the resource needs and the ability to carry out concurrent SIT activities, which approach would you select for this system and why? A E F G Harrow_forward
- Developers often think about software consistency in terms of faults and mistakes. Faults are problems that engineers may identify by looking at the code, such as never-ending loops or phrases lacking commas. Failures are those that are visible to the customer, such as a server crash or the improper execution of a task. Since a consequence, defects in programs may exist but never become errors, as the criteria for a flaw to become a failure are never fulfilled. How significant are software faults in this system of mistakes and failures? Is there a fault in every imperfection? Is it true that flaws come in all shapes and sizes?arrow_forwardThe construction of models for software-intensive systems should take into account what points of view are relevant.arrow_forwardConsideration need to be given to the use of structured language to describe processes that are not included in an analysis of systems, despite the fact that this is not an absolute requirement?arrow_forward
