Importance Of Software Engineering In Software Development

1233 Words5 Pages

1.1 INTRODUCTION

This unit provides an overview of software engineering concepts, the importance of software engineering during software development. Types of software are described and how certain software engineering tools, techniques, and methods may be applied to specific software. During the software development process, software engineers must adhere to ethical and professional issues in an organization.

Upon successful completion of this unit the students should be able to:
• Outline the importance of software engineering during software development
• Apply software engineering tools, techniques and methods in a specific environment
• Evaluate and discuss various types of software
• Have a thorough understanding of ethics at an organisation …show more content…

The vendor must design and implement the software specifically for that customer, hence the name “customized” (Sommerville, 2016:21). Examples of customized software include control systems for electronic devices, specific business processes and air traffic control systems.

The main difference between generic and customized software is that generic products are controlled by the vendors whereas customized are controlled by the organisation buying the software. In terms of specifications, generic specifications are done by the vendors whereas customized specifications are done by the organisation buying the system; the organisation will outline specific requirements and their needs.
Definition of Software engineering According to Sommerville (2016:21), software engineering is defined as an engineering discipline that is concerned with all aspects of software production from the early stages of system specification through to maintaining the system after it has gone into …show more content…

A high-quality software must be produced.

There are two reasons why software engineering is important:
• It is cheaper to use software engineering methods in the long run, since most individuals and society rely on advanced software systems.
• Reliable, efficient, trustworthy and economically sound systems must be produced by software engineers. If good software engineering practices are not followed, this could lead to higher costs for testing the software, quality assurance (meeting standards) and long term maintenance.
Software engineering makes use of software processes. According to Sommerville (2016:23), a software process refers to a sequence of activities that lead to the production of a software product. There are four fundamental activities which are commonly used in software processes:
a) Software specification – this is the stage where software engineers and customers sit down to define the software to be produced and constraints on the software.
b) Software development - this is the programming of a software by the development

One of biggest roadblock that companies have to face is to invest a lot of money on implementing a software system and have employees ignore it and keep trying to do the task in their own way. This the reason why the provider that you choose for implementing your software have to be a natural fit for the organization. If the owners and employees have the same passion and understanding of the product that they would implement the result would be a success (Phillips, 2016).

In this modern world the need for designing and developing an application with good secure features is very high. I have also learned what an error exceptional handling is and why is it important in code review. I have also learned that in developing a software product or in the software development life cycle process, a software product must be teste in earlier stages and very frequently. This recalled my knowledge of secure software development life cycle. One must know the importance of secure software development life cycle.

Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.

Software updating If you want to protect your computer from any malicious activities, therefore, you should update your computer security software regularly. It is very important to update a software security software because some weakness software may allow a hacker or viruses to gain access to your computer. Moreover, update a software can able to make your computer faster. If you do not update the security software that means there will be changes to get attacks by hackers and viruses so you should update a security software regularly.

It is important to emphasize that these challenges were brought about by poorly defined goals and the scope was usually unclear. This meant the projects usually tended to go beyond the estimates as the project developers tried to fix newly developed ideas in to the development process. the phase gate model was developed to give an outline of the project development process to offer solutions for managing newly launched

This approach centers on people, communications, the anticipated product and its flexibility. The concept of this approach is similar to that of the traditional management approach: generating plans and requirements, evolving the anticipated product, incorporating it with other products as required then testing it and debugging technical hitches if any is found, then lastly fitting it for use (Rose, 2010). In this approach, as a replacement for focusing on the phases all at once like it is done in the traditional approach, the entire project is fragmented into smaller segments known as scrums after which the scrums are taken as smaller projects and dealt with according to the traditional

Unit 2 discussion Assignment Using one of the referenced website articles discuss how OS creates the illusion of virtualization by virtualizing the CPU. By running one process, then stopping it and running another, and so forth, the OS can promote the illusion that many virtual CPUs exist when in fact there is only one physical CPU (or a few). last week we learn and discussed about one of basic and fundamental concepts and what about of the operating system and in generally how it 's working and it 's own component that related to complete the work as a group like a team. from this perspective, I would use one of the reference website articles that given for this week and introduced to the concepts of operating systems and discuss one of the most fundamental abstraction that the operating system provides to us to use .

the more options there and can be used to violate privacy. Most people consider they have little, if any, control over their personal data. Better encryption and the minimizing of data requirements aids in this goal. PIMS systems are a new technological developing that promises to aid the privacy dilemma. The PIMS system consists of a user’s server, running the services selected by the user, storing and processing the user’s data locally instead of on an online server.
