When dependency on software and computers became more important, software grew in size and became a necessity for businesses and users all over the world. In the last 30 years, we have seen an unparalleled explosion in the amount of software produced and used by our modern society. There is now a need to set concrete objectives (or functional requirements), predict necessary resources (like cost estimates) to attain those objectives, and manage customers' expectations. As you review the material in this unit, compare and contrast software engineering with computer science. These two disciplines are closely related, but they have some differences. As you work through this unit, spend some time reviewing the software characteristics and the code of ethics used in the professional practice of software engineering.
Completing this unit should take you approximately 3 hours.
The software development life cycle (SDLC) is the process for planning, creating, testing, and deploying an information system. There are different approaches to break down the work when developing software systems. Conceptually, each model provides specific guidance to the sequencing and repetition of life cycle activities to deliver high-quality software systems.
As you review this unit, try to see the similarities in these categories of life cycle models. This will help you grasp the basic concepts of SDLC. This unit connects strongly with Unit 9: Project Management, since choosing and managing a software life cycle process is a central component of project management.
Completing this unit should take you approximately 4 hours.
Many believe that good design is fundamental to creating successful software. The first step in software creation is to gather requirements. Notations, such as UML, allow us to articulate complex ideas succinctly and precisely. Designing software requires the use of certain industry-standard design tools, and mastery of them is essential to becoming a capable software engineer.
This unit will introduce you to UML, a standardized general-purpose modeling language for creating visual models of object-oriented software. This unit aims to give you a comprehensive understanding of UML, the five fundamental artifacts of UML, and modeling concepts, as well as the modeling concepts' relationships to the terms system, model, and view.
Completing this unit should take you approximately 4 hours.
Requirements gathering requires the software engineer (in this case, a business analyst) to interact with the stakeholders, including customers and users, to gather/collect information about what the software system being developed needs to do. There is also the situation where vendors are subcontracted to develop all, or some components, of the software systems and/or develop the hardware that the software will run on. In this case, the vendors bid on the subcontract by providing a proposal in response to a request for proposals. In this unit, you will learn the data/information types, data collection techniques, and data collection and application types.
Completing this unit should take you approximately 3 hours.
Requirements elicitation is when software engineers interact with the stakeholders, including users, to gather information about what the software system needs to do. In this unit, we examine what the software engineer does to elicit, analyze (or translate), validate, and manage this phase of the life cycle. Each step requires working with the customer to achieve a common understanding of the customer's goals. This set of activities is referred to as "analysis", and focuses on what the application will do, whereas "design" describes how the application will work.
There are many ways to elicit and analyze customer requirements. The three most commonly used methodologies are data-oriented, process-oriented, and object-oriented. We will examine the conceptual foundations, activities, and deliverables in each of these methodologies. As you review this unit, focus on the object-oriented methodology and how it applies to software requirements and analysis. You will put it all together later in this course as part of a case study.
Completing this unit should take you approximately 4 hours.
After requirements and analysis, a software engineer must transform the analysis model into a design model that can be implemented in a specific hardware and software environment. In this unit, we will discuss the principles of design and architecture design. Just as there are various methodologies for requirements analysis, we will look at three corresponding methodologies of the design model (data-oriented, process-oriented, and object-oriented). As you review this unit, focus on the object-oriented methodology and how it applies to software design. You will put it all together later in this course as part of a case study.
Completing this unit should take you approximately 9 hours.
Implementation, also known as programming or coding, is the process of using a programming language to convert specified requirements into software source code and later into compiled code for execution. Programmers can use automated tools to convert design requirements into code.
Sometimes, vendors are subcontracted to develop all or part of the software, and even the hardware that it will run on, according to specified requirements. In these situations, vendors will bid on the subcontract by providing a proposal.
Completing this unit should take you approximately 2 hours.
Testing is the process of finding errors and is one of the last activities in the software life cycle. In testing, we look to validate that software requirements analysis, software design, and software implementation mesh together correctly to deliver a software system that performs as expected, functionally and non-functionally.
As you review this unit, note the three levels of a test plan: unit, integration, and system. Each of these levels of test plan assures the quality of the overall software from varying levels of granularity. In your own practice as a software engineer, be sure to incorporate these levels of testing as this is the last stop before the software goes out the door representing your professional work and code of ethics.
Completing this unit should take you approximately 3 hours.
Project management in a software engineering environment is unique because of the technical aspects of a software project. The project manager's role is different from that of the software engineer's. While software engineers are generally accountable for the technical aspects of a project, the project manager is accountable for organizational aspects.
As you review the materials of the unit, try to connect this unit with what you have already learned about the software development life cycle. You will see that the success of an SDLC depends on people, process, and product. Project management is the glue that holds these aspects together.
Completing this unit should take you approximately 4 hours.
There are different principles necessary to practice software engineering. In this unit, you will use these principles and main software engineering concepts to practice professional issues that a software engineer might face. This includes identifying input and output and main stakeholders, developing a timeline with checkpoints for delivery of key deliverables, creating the main UML diagrams, and using different testing strategies and system quality evaluation methods.
Completing this unit should take you approximately 5 hours.

The purpose of this course is to present software engineering as a body of knowledge. The course is designed to present software engineering concepts and principles in parallel with the software development life cycle. The course will begin with an introduction to software engineering, giving you a definition of this body of knowledge, as well as a discussion of the main methodologies of software engineering. You will then learn about the Software Development Life Cycle (SDLC), major methodologies followed by software modeling using Unified Modeling Language (UML), a standardized general-purpose modeling language used to create visual models of object-oriented software.
You will go on to learn about the major phases of the SDLC: analysis, design, coding/implementation, and testing. You will also learn about project management for the purpose of delivering high-quality software that satisfies customer needs and is within budget. By the time the course is complete, you will master software engineering concepts, principles, and essential processes of the SDLC. You will demonstrate this knowledge by creating artifacts for requirements gathering, analysis, and design phases using UML.
