Software Engineering


Definition

The IEEE Computer Society defines Software Engineering as the application of a systematic, disciplined and quantifiable approach to the development, maintenance and operation of software.


History

  • In the 1940s, the first software programs were written in machine code.

  • In the 1950s macro assemblers and interpreters were created to improve productivity and quality.

  • In the 1960s, the second generation of compilers and interpreters were being used.

  • The 1970s gave rise to the microprocessor and the gain of software collaboration tools.

  • In the 1980s, saw the personal computer land on everyone's desk.

  • The 1990s saw the development of object-oriented programming and the further maturity of the Software Engineering practices.

  • 2000s have seen the rapid advancement of the performance and storage of computer servers and personal computers.


    Engineering Disciplines

    Requirements Engineering is the systematic collection of customer needs or conditions for a new software application, or a new release of a already existing application.

    The requirements must be measurable and testable. Prototyping and use case creation are examples of solutions to the difficult process of gathering, analyzing and documenting of the customer requirements.

    Software Design After the Requirements Engineering is done, software architects begin the process of planning and designing the software to meet software requirements.


    Software Engineering Considerations

    In addition to meeting the requirements, there are many considerations to weigh when designing a software product.

    • Compatibility
    • Extensibility
    • Maintainability
    • Reliability
    • Robustness
    • Security



    Software Design

    A smart design will greatly aid in a development organization's ability to support a software product.


    Software Construction

    Software building is the process of coding, compiling, verifying, testing and debugging of software.


    Software Testing

    Software Testing is the process of measuring the behavior of a software program. The quality of the testing process usually measured for correctness, completeness and security.

    Software testing has evolved from an activity performed after the product is considered code complete. To function performed all the way through and after the construction phase.


    Software Configuration Management

    Software Configuration Management are the practices and procedures for administering source code, producing software builds, controlling change, configuration management and 3rd party software control.

    Specifically, SCM ensures the integrity, reliability and reproducibility of developing software products from conception to release. During projects and releases, SCM facilitates timely communication, enforces policy and technical standards and manages hand offs between environments and teams.

    SCM is truly Software Engineering.


    Software Maintenance and Support

    Software Maintenance and Support is the phase after the product is deployed or sold to customers. It is the processes and practices evolved with keeping the product running and in good health.

    Many software development organizations have attempted to invest as little as possible in the maintenance and support. It was believed that investing more in the development of the software was a more cost beneficial to the organization.

    However, it is now accepted that prolonging the life of a release can be more beneficial use of resources. So, instead of staffing the Support team with less experience software engineers, they are now use more experienced software engineers to prolong the life of a given product.

    Traditionally, Software Maintenance and Support dealt with the fixing of defects, performance improvements or the customer specific customizations to adequately run the software.


    Software Quality

    Software Quality at it's essence is the processes involved with achieving a predetermined level of customer requirements and product performance.

    The ability to achieve a specific level of Software Quality requires.

  • Determining Quality Requirements

  • Determining the Processes to Achieve the Quality Levels


    Software Engineering Best Practices

    There are many Software Engineering Best Practices.

    Here are some of the more commonly used SE Best Practices

    • Iteratively Develop Software
    • Actively Manage Specifications and Requirements
    • Develop and Leverage Component-based Software
    • Continuously Review and Improve your Software Development Practices
    • Verify and Quantify Software Quality
    • Manage Software Change

    Software Development Life Cycle

    Software Development Life Cycle is the process in which you encapsulate your software development.

    Specifically meaning, it is the processes, standards and tools that your software development team uses to ensure the accuracy and timeliness of your software development efforts.

    For more information about Software Development Life Cycle


    Software Development Process

    Software Development Processes are standards that a Software Development Team uses to help manage, control and report on their software development.

    Here are some very typical SDP Steps:

    • Plan
    • Define
    • Construct
    • Test
    • Deploy

    For more information about Software Development Process


    Software Development Life Cycle Methodologies

    There are several different Software Development Life Cycle Methods.

    Some have been around for years and years and some are relatively new.

    • Waterfall
    • Iterative
    • Top-Down
    • Feature Driven
    • Prototyping
    • Hybrid
    • Object-Oriented
    • Agile

    Agile SCM Implementing Agile Software Configuration Management processes and practices will help your ability to successfully implement Agile software development processes.

    Agile Software Agile software attempts to minimize risk by developing software in short iterations. This development methodology is about adaptability. Because of the chaotic nature of software development, it may be impossible to control or to predict.

    Agile Source Code Providing agile source code control processes and procedures greatly aids an organization's ability to successfully implement Agile software development processes.

    Feature Driven Development Feature Driven Development, FDD, is a short-iteration development process. It consists of five basic activities: Develop an Overall Model, Build a Feature List, Plan by Feature, Design by Feature, Build by Feature

    Software Development Processes The Software Development Process, SDP, is the methodology used by a development team to produce software.

    Software Development Life Cycle Models Software Development Life Cycle Models are systems and processes a software developer or software development team leverage to systematically produce software: Agile, Feature Driven Development, Waterfall, Object Oriented, Prototyping.

    Software Engineering The IEEE Computer Society defines Software Engineering as the application of a systematic, disciplined and quantifiable approach to the development, maintenance and operation of software.

    Software Engineering Best Practices Software Engineering Best Practices, SE Best Practices are the processes and techniques that have been proven over time to provide successful Software Engineering Results. When searching the Internet, there are many Software Engineering Best Practices to be found on the World Wide Web. Here are some of the more commonly used and proven SE Best Practices.

    Software Requirements Software Requirements are the details and specifications about how the software should act and behave. There are several types requirements: Business, Functional, Non-Functional, User and System Requirements.

    Software Requirements Template Software Requirements Template is an outline of a Software Requirements Specification that was used in a large software company. It is not meant to be the one and only way to do cover your Software Requirements. It is intended to be a starting point for you or your organization to approach Software Requirements.
