LO1: Understand different software processes and how to choose between them.

“A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction”.

Based on the above definition, Cloud Computing has three service models known as Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS). By using your own words, differentiate between these three service models and give an example to each one.

Learning Outcome(s):

LO1: Understand different software processes and how to choose between them.

Generally, process models can be categorized into three main groups namely:

· Prescriptive Process Models

· Evolutionary Process Models

· The Unified Process

Now, provide an example of Process Models of each one of these group explaining when we should use it and when we should not. The following table can help you to organize your answer.

Learning Outcome(s):

LO1: Understand different software processes and how to choose between them.

Software development myths defined as wrong beliefs about software and the process that is used to build it. Today, professional software engineering can easily recognize myths for what they are. However, some old myths remain!

Using your own words, explain why some myths still consider as an issue in Software development supporting your answer with an example of a myth with reality of this myth?

Learning Outcome(s):

LO1: Understand different software processes and how to choose between them.

In these days, when building a software, we are faced with many challenges. In order to overcome these challenges, we need to take into consideration the following statement “software in all of its forms and across all of its application domains should be engineered”.  To achieve this statement, simple realities must be recognized!

Using your own words, discuss at least three realities that can achieve the above goal.
