Alpha Technologies USA Inc. strongly believes that extensive planning should go into a network installation/implementation for quality purposes. A good project plan will help identify any strengths, weaknesses, opportunities, or threats. The plan should clearly define the tasks, and the order in which tasks are completed. Our main goal during the structured systems analysis is to accurately represent user and client needs. To make the project manageable, it will be divided it into modules that can be more easily maintained and changed.
Structured systems analysis has the following characteristics:
The system will designed in a top-down sequence for better manageability.
During the design project, several techniques and models can be used to:
Characterize the existing system,
Determine new user requirements,
And propose a structure for the future system.
A focus is placed on data flow, data types, and processes that access or change the data.
A focus is placed on understanding the location and needs of user communities that access or change data and processes.
A logical model is developed before the physical model. The logical model represents the basic building blocks, divided by function, and the structure of the system. The physical model represents devices and specific technologies and implementations.
Specifications are derived from the requirements gathered at the beginning of the top-down sequence.
A network that is a patchwork of devices strung together, using a mixture of technologies and protocols, is usually an indicator of poor initial planning. These types of networks are susceptible to downtime, and are difficult to maintain and troubleshoot. Therefore, at the planning stage, our network engineer needs to take account of the existing equipment and technologies the network would have to operate with and their compatibility with the proposed equipment.
The planning of a local area network (LAN) has six distinct phases:
Requirements Gathering/ Analysis Necessary
Design and Selection
Review and Evaluation
Maintenance and Support
All the necessary information needed is gathered during a site survey and also from the client end users. A site survey provides much information to the network engineer/designer and creates a proper starting point for the project. It shows what is already on site, and gives a good indication as to what is needed.
Devices and cabling must be selected based on the requirements outlined in the Analysis Report. Multiple designs may also be created to view the LAN from a documentation perspective and evaluate trade-offs in performance and cost. It is during this step that any weaknesses of the design can be identified and addressed.
During this phase, all configuration to network devices and physical connections are started, if there are tasks that have been overlooked in the earlier phases, they must be corrected during implementation. Creation of a good implementation schedule and allowing for some additional time for unexpected events keep disruption of the client’s business to a minimum. During the implementation, there should be strict adherence to standards, such as color codes, operational limits, etc. Staying in constant communication with the client during the installation is always critical to the success of the project.
The network is brought into service in what is termed a production environment. Prior to this step, the network is considered to be in a testing or implementation phase. Operations objective is to achieve the lowest latency and highest frequency possible to ensure business continuity.
After the network is operational, the design and implementation will need to be reviewed and evaluated. For this process, the following steps are recommended: Compare the user experience with the goals in the documentation and evaluate if the design is right for the job. Compare the projected designs and costs with the actual deployment. This ensures that future projects will benefit from the lessons learned on this project. Monitor the operation and record changes. This ensures that the system is always fully documented and accountable.
Custom plans take into consideration your company's network, how you adopt technology, user computer ability, IT budget, and how involved you want to be with your network and budget.
