An introductory course on Software Engineering remains one of the hardest
subjects to teach largely because of the wide range of topics the area encompasses.
I have believed for some time that we often tend to teach too many
concepts and topics in an introductory course resulting in shallow knowledge
and little insight on application of these concepts. And Software Engineering
is finally about application of concepts to efficiently engineer good software
The project manager must set expectations about the time required to complete the software among the stakeholders, the team, and the organization’s management.
If those expectations are not realistic from the beginning of the project, the stakeholders will not trust the team or the project manager.
Software requirements are documentation that completely describes the behavior that is required of the software-before the software is designed built and tested.
Requirements analysts (or business analysts) build software requirements specifications through requirements elicitation.
Interviews with the users, stakeholders and anyone else whose perspective needs to be taken into account during the design, development and testing of the software
Observation of the users at work
Distribution of discussion summaries to verify the data gathered in interviews...
Quality means “conformance to requirements”
The best testers can only catch defects that are contrary to specification.
Testing does not make the software perfect.
If an organization does not have good requirements engineering practices then it will be very hard to deliver software that fills the users’ needs, because the product team does not really know what those needs are.
People begin programming before they understand the problem
Everyone likes to feel that they’re making progress
When the team starts to code as soon as the project begins, they see immediate gains
When problems become more complex (as they always do!), the work gets bogged down
In the best case, a team that begins programming too soon will end up writing good software that solves the wrong problem
Software systems Ubiquitous, used in variety of applications
- Business, engineering, scientific applications
Simple to complex, internal to public, single function to enterprise-wide, one location to distributed, batch or real time, informational to mission-critical,…
A change in project priorities throws the team into disarray
This usually comes from a lack of understanding of the scope of the project
When the engineers don’t understand the users’ and stakeholders’ needs, they build the wrong software
And they might not find out that there’s a problem until after the work is done!
A review is any activity in which a work product is distributed to reviewers who examine it and give feedback.
Reviews are useful not only for finding and eliminating defects, but also for gaining consensus among the project team, securing approval from stakeholders, and aiding in professional development for team members.
Reviews help teams find defects soon after they are injected making them cost less to fix than they would cost if they were found in test.
All work products in a software project should be either reviewed or tested.
Most software is built in organizations for people with specific needs.
A stakeholder is a anyone who has an interest (or stake) in the software being completed
A user is someone who will need to use the software to perform tasks.
Sometimes stakeholders will be users; but often the stakeholder will not use the software.
For example, a senior manager (like a CEO - chief executive officer or CTO - Chief technology officer in a company) will usually have a stake in the software that is built (since it affects the bottom line), even if she won’t ever use it....

Java Software Solutions teaches a foundation of programming techniques to foster well-designed object-oriented software. Heralded for its integration of small and large realistic examples, this worldwide best-selling text emphasizes building solid problem-solving and design skills to write high-quality programs.
Embedded systems are no longer resembled t from our lives without them. Because of their specialization of these are realized increasingly interacting hardware and software components. This makes a holistic, about hardware and software boundaries, continuous amplification ndnis problem of verification is required. This textbook serves as an introduction to guide the systematic verification of embedded systems, both in specialized procedures for hardware and software verification and the verification of the interfaces.
Chapter 2: Software & Operating System
What is the software? How is software categorized? What is an operating system ? What does an operating system do?
What’s the software ?
Software is the instructions and associated data, stored in electronic format, that direct the computer to accomplish a task. A computer program is a set of detailed, step-by-step instructions that tells a computer how to solve a problem or carry out a task.
How is software categorized?
Software is categorized as either application software or system software.
A search for ‘Software Defined Radio’ on Amazon.com at the end of 2010 shows
that almost 50 books have been written on the subject. The earliest book was
published in 2000 and a steady stream of new titles has been coming out since.
So why do I think that yet another book is warranted?
SDR is now a mature field, but most books on the subject treat it as a new
technology and approach SDR from a theoretical perspective. This book brings
SDR down to earth by taking a very practical approach. The target audience is
practicing engineers and graduate students using SDR as a tool rather...
Geo-electrical tomographical software plays a crucial role in geophysical research. However, imported software is expensive and does not provide much customizability, which is essential for more advanced geophysical study. Besides, these programs are unable to exploit the full potential of modern hardware, so the running time is inadequate for large-scale geophysical surveys. It is therefore an essential task to develop domestic software for overcoming all these problems.
Software error detection is one of the most challenging problems in software engineering. Now, you can learn how to make the most of software testing by selecting test cases to maximize the probability of revealing latent errors. Software Error Detection through Testing and Analysis begins with a thorough discussion of test-case selection and a review of the concepts, notations, and principles used in the book.

Once the SRS has been approved, implementation begins. Programming teams have many options:
The programmers can simply start building the code and create the objects and user interface elements.
Designers can build a user interface prototype to demonstrate to the users, stakeholders and the rest of the team. Any code used to develop the prototype is typically thrown away once the design has been finalized.
Pictures, flow charts, data flow diagrams, database design diagrams and other visual tools can be used to determine aspects of the design and architecture.
