Prepare a report to explain the following principles of software design.
Task 1 (P5)
Define and describe:
• software development life cycle – activity and purpose of each stage
• software structures such as functions, procedures, classes and objects
• software design concepts such as modularity, readability, reliability, portability and maintainability.
Task 2 (M1)
Discuss the importance of the quality of code in terms of modularity, reliability, usability, portability and maintainability.
Task 3 (D1)
Discuss the factors that can improve the readability of code. Contents

These requirements are translated into design. A code is produced as according to the design that is created which is according to the requirement. This is called the development phase of the lifecycle. After coding and development the testing verifies the deliverable of the implementation phase against requirements [3].
2.2) what are the benefits of the Software development life cycle process?
The main aim of the lifecycle process is to produce a product which would be cost efficient, effective and also up to the high standard. Once the application is created, the lifecycle determines the proper arrangement and decommissioning of the software once it becomes legacy [5].
The life cycle contains following stages:
Requirement gathering and analysis
Design
Implementation or coding
Testing
Deployment
Maintenance
2.3) Requirement gathering and analysis
This phase is critical to the success of the project. In this phase the purpose of the software or system should be determined. This is the phase where you can set the requirements that the software needs to fulfil when it is completed. Hence this stage is the main focus of project managers and stakeholders.
This phase involves more communication to get the detailed description from the managers and the stakeholders as to who is going to use the system? How will they use the system? What data
Outcome measures assess whether the interventions to improve medication safety practice will be successful. During the interview of the new employee, competency evaluation related to medication administration will be applied first. In addition, during the orientation for these new employees, adequate training will be provided to ensure the importance of preventing medication errors. They will be given a list of similar and look-alike medications and will focus on medications that cause the most adverse reactions when errors may occur. Then, after training and when staff start working, they will be supervised during their first few months. When they are not supervised, they will be assessed and evaluated for any errors. During this process,
A: In the software lifecycle there are 4 phases that are derived from the old System Development Life Cycle (SDLC) and they are as follow; Planning, Implementation, Maintenance, and the Removal process. The planning phase is defined by all planning activities including the analysis of the software to be installed, verification of its compatibility, supported methods of installations, and the identification of any risks associated with the software and the desired deployment method. The Implementation phase is used to prepare for deployment such as; creating a shared access location for files and creating or using the appropriate package files. After all these steps have been
I was wondering if you could contact the residents in 1103 about their two dogs barking?
The system development life cycle is a formal four-step process that can be followed in order to identify a problem and solve it. The first step is
Research indicates that as many as 13% [Smith 2005] of primary care visits have missing clinical information. A patient's health information is potentially distributed across a wide range of locations including their general practitioner, hospitals, imaging centers, specialists and allied health practices.
Evaluate the skills and techniques required to successfully perform in two different land-based outdoor and adventurous activities
In this section I am going to evaluate the effectiveness of Lay people within the English Legal System.
This is the phase where the requirements are noted, feedback regarding requirements are obtained from users
The development phase is where the system is brought to life. In this phase, developers will build the system based on the models that were developed in the design phase. This phase is usually one of the longest on the whole process as it is when the actual creation takes part. If instead of developing the system, the practice is going to adopt one that is already developed, managers will seat with their counterparts from the systems to be adopted to discuss important aspects and details of the deal.
Once code has been generated, program testing begins. The testing focuses on the logical internals of the software, ensuring that all statement have been tested, and on the functional externals; that is, conducting test to uncover errors and ensure that define input will produce actual results that agree with required results.
Define Phase implementation: A Project Team was formed and a manager from the procurement department had the following responsibilities. This phase deals with defining.
The researcher designed and developed a TITLE using Programming Language. The general purpose of this study covered_____________________.
In this stage data which is used for strategic planning is gathered which is used for analyzing what are the organization needs, what is the current stage of organization and correction of data from the past system is to be done. By this further steps would be
Developing the product: In this stage of SDLC the actual development starts and the product is built. The programming code is generated as per DDS during this stage. If the design is performed in a detailed and organized manner, code generation can be accomplished. Developers have to follow the coding guidelines defined by their organization and programming tools like compilers, interpreters, debuggers etc. are used to generate the code. The programming language is chosen with respect to the type of software being developed.
Stage 1: The problem situation: unstructured. At this stage, the system practitioner recognizes that the situation is unstructured and is not clear to anyone, and that there are so many relationships included. So systems practitioner is going to find ways to explore and attend these relationships alongside the overall situation by looking at it holistically and taking the initiative to understand everything in, and anything that might lead to the situation. It can be achieved
