Introduction to System Development

The new system development consists of a series of hardware system, or a software system or a combination of both to meet the expectation of the customer. The system is a set for interacting the components and forming an integrated whole term that helps in creating a better component to integrate with the other components of software for creating a whole system. The system development comes into play when there are proper analysis, designing or the modification, acquiring of a new software or hardware & training to make sure that a system is working in a proper manner (Zakeri & Syri, 2015). Hence, the statement is true as the system development relies highly on the components that are developed out of the client organization.

The preliminary analysis is about reviewing for a technical feasibility and economic standards. It is important for the system analyst to work on different stakeholder groups to determine specific requirements. This will include procedures and documentation, where the key players are interviews and the data requirements are set. The system development is about conceptual model that helps in understanding information system development with possibilities to complete activities in a phase which are in parallel with another phase (Ling, Heidrich & Roskilly, 2016).

It is important for the planning standards to process the defined and discrete activities to work on completing activities in a particular project. There is a need to identify the scope of new system with ensuring about the feasibility plan. The activities are defined through confirming project feasibility problems, producing the project schedules and then staffing the project.

System Analysis

The software and network engineer requires to work on gathering data and review about written documents, interviewing employees and managers to observe people and the different processes that are set at work. The analysis of the data is to gather the information and analyze the different analytical tools. The modeling tools help in enabling the system with the data flow diagram which shows a proper flow of data through the system (Martin, Iribarren, Garcia & Dufour, 2017). It helps in analyzing the process of a system with the output, and the inputs that are taken. Once the report is completed, the analysis is done for one to document about the phase.

The report is to manage the three parts which are about how the existing system works, explaining problems about the existing system and then describing requirements for new systems. The recommendations are made on what has to be done next. The end user requirements need to be determined and documented properly with system expectations based on how they are performed. The study is about projecting the information in organization manner, which is important for a stronger communication level with clients.

It is mainly to make sure about a clear vision for a particular product and the functions which are relevant to it. The analysis phase requires to focus on activities like gathering information, defining the different system requirements and building prototypes which are for a better discovery of requirements (Hertiwich et al, 2015). There is a need to generate and evaluate the alternatives along with reviewing recommendations with management activities as well.

System Analysis

Designing the system

1. The Preliminary Design: This is about highlighting the functional capabilities for the information system to review about the requirements of system and then considering about the major components of the system as well. The prototyping is important to make use of workstations, case tools and other applications of software to work on building model components. This makes it possible for a system to be quickly tested and evaluated properly. The system requires to handle the decisions that are made with integrating the network through application architecture. It also make use of the user interface, with integrating the data and the prototype for designing details. The system needs to work on running productivity with upgrading or enhancing the system capabilities that will support the users. The approaches to system development are related to structured programming which includes the sequence of program statements. Here, the system consists of the objects with object-oriented analysis (Omar et al., 2014)
2. The detail design: The preliminary designing is about how the system information is designed for delivering the capabilities for handling the output requirements, input and other storage problems which includes system controls and backups as well. The detailed designing highlights on understanding the requirements of a customer, their components and the proper security level that helps in checking modules and architecture development which goes through system. The general system designing can be done through determining about how the system looks and the functions are detailed, and system designing is produced to meet the functional requirements.
3. The writing of reports and the work of preliminary designing end up in a larger and a detailed report. The report is made for the senior management to make a particular type of presentation or speech.

Developing a System 

1. The system is developed or acquired though the software where the system analyst need to properly address on make or buy decision.
2. The hardware is acquired with testing the system and then handling the unit testing.

This phase requires to properly focus on specifications and then plan about configuring the fine-tuning for hardware to meet the requirements and functions (Eleftheriadis, Mumovic & Greening, 2017). The system is ready for the deployment and installation in customer premises, considering it becomes live and productive. The training is also needed for the end users so that they are able to work on the implementation of the system by matching its complexity and solution.

The approaches for system development defines additional types of objects which are important for the communication with people and the devices in system. It requires a proper writing of statements through use of programming languages.  The development method is defined through alternatives that are for rapid application development and spiral model to work on system development and methodology which is built, tested and then reworked. This is till the time when there are necessary and acceptable prototype development for a system or product.

Implementation & Maintaining the system

The direct implementation phased, or pilot implementation is important for maintaining a system with proper auditing and periodic evaluations that could be done through making changes based on the different and new conditions. The different components help in creating integrated system with obtaining and analyzing better outputs, in the way it functions. This could be done by real users or through a team of special personnel with systematic and automatic procedure to ensure about the actual outcomes (Hauschild & Huijbregts, 2015).

Conclusion

The analysis and the designing includes the preliminary investigation to conduct and propose better solutions with describing costs and benefits effectively. The system planning requires a proper setup with defining problems and objectives like the personnel and the costs. There is a need to study about the ability for proposing different alternative solutions which are found after meeting the clients and the suppliers. The new system development also relies on understanding the structured and risk averse methodology designed for managing the larger projects that include the programmers and systems with larger impact on organization.
