Application development refers to a process of deploying, testing, creating and planning an information system. Sometimes applications are prepared for a process of automation, generating a product to identify business requirements or to get rid of competition by remaining innovative. Critical thinking and professionalism provide support to work independently and as a significant team member; these are the core skills for the person who is developer.
In this unit, students will have an introduction to application development. It is prepared to simulate the responsibilities and roles of the commercial developers working in an appropriate environment of business environment with accessibility to the small colleagues’ team. Initially, students also get the instruction on the problems related to business and will require the adaptation and appropriate method of use and analysis practice, discussing and breaking down the issues, then designing, deciding, testing and creating possible solutions. Learners must be free to evaluate, select and debate multiple development and designs of methodologies. They have to depend on their own constitutions and judgments.
Despite having these topics, they have to include units such as developer and design documentation, research user requirements and problem analysis principles and methodology of design, considerations of security, software development, life cycle development, methodologies, peer and team reviews, development techniques and tools.
When this unit is completed, learners will have the potential to produce documents of software design by identifying the problems related to business. Moreover, they will also deduce an accurate solution which includes a set of initial requirements. They will also have the potential to use and select the development and design methodologies with the techniques and tools associated with business application creation. They will also have the potential to work as a team and individually to produce and prepare a functional application of business with identifying and planning improvement, and supporting documentation for the business evaluation. Additionally, they have to evaluate the performance against the document of software design and the main needs.
Unit Objectives
The significant aims of the unit 22 application development are here. You have to grasp these concepts to move ahead in your HND course.
- To prepare practical skills in building and designing applications by teaching learners the way to identify requirements, implement software and plan solutions utilising industry-relevant languages, frameworks and tools.
- To improve recognition of the software development life cycle SDLC that drives learners` potential to apply structured methodologies, documentation and testing practices standard within the real-world environment of development.
- To make problem solving and critical thinking potential strong by guiding the learners for the identification of user requirements, procedure efficiency and generating logical designs with maintainable and sustainable applications.
- To prepare learners ready for roles of the industry in software and application development by generating professional communication skills, technical competence and potential to work collaboratively or independently on project development.
