Implementing is putting (a decision, plan, agreement, etc.) into effect. Systems implementation is the delivery of that system into production (that is, the day-to-day business or organization operation). It is important to understand that this topic isn't about building or programming a system, but rather making the system live.
There are variety of options that a project manager could consider when implementing a solution. There are advantages and disadvantages to each type, and the choice usually depends on the client organizational setup and the complexity of the solution to be implemented. And These are implementation choices that are available to a project manager:
1-A parallel implementation or approach: It implies that a new solution is implemented parallel to the current operating system in use. Those who are using the system will not see major downtime once it is implemented. The trick here is to implement the system. Once the new solution is tested and running, it is “switched on” and the older version is “switched off”. The advantages with a parallel implementation include less disruption to the business, and no loss of business if the new system suddenly fails.
2-A phased implementation: Sometimes trying to implement a solution all at once is not feasible because many clients have essential operations that run during normal working hours and cannot afford the luxury of having their entire operation close down for a lengthy period in time. Often, clients have front office staff that attend to these operations (such as call centers, help desks, etc.), and they work in 24-hour shifts. This is why many clients approve of a phased implementation approach, and the project team must ensure that the phased implementation is possible. This approach involves implementing the solution to a certain number of users and then rolling them onto the new solution, while the rest of the users are rolled out in a similar fashion until the entire solution is rolled out within the client environment.
The phase approach works well because there is minimal disruption to the client's operation, and problems are resolved quickly. The phased approach could also be used if there is more than one department. The project manager could decide that implementing the solution in one department at a time could be more reliable than trying to roll out all departments at the same time.
3-A crash implementation: Be careful planning needs to take place when considering a crash (also known as full-blown) implementation. It takes an incredible amount of planning and re-planning to ensure no problems arise. In fact, with this type of implementation, the necessary contingencies need to be prepared and reviewed well in advance of the actual implementation, in order to minimize any potential failure. The necessary IT support staff also need to be available on the chosen implementation period. A full-blown implementation should be scheduled to take place over a slow period, such as a holiday or weekend.
Software integration is the process of bringing together various types of software sub-systems so that they create a unified single system. Software integration can be required for a number of reasons, such as: Migrating from a legacy system to a new database system, including cloud-based data storage.
There are 7 Phases of System Integration:
1-Requirement and Specification: Before initiating to working on the actual system integration process, DastN lists out the detailed requirements the customer has given. Efficiency is required in framing the requirements of both the systems to be integrated to make this process easy and seamless.
2-Feasibility Analysis: Once the requirements, definitions and specifications referencing the systems to be integrated are listed down, feasibility analysis takes place. The feasibility study includes complete analysis of the system integration project based on the intense research to support the decision-making process.
3-Architecture and Development: This is the system construction phase which includes system architecture plan regarding how the system should be integrated to the other comprehensive systems. Blueprints of the integration plan including the proposed architecture plan and much more are also created.
4-Management Plan: Once the complete plan of the system integration process is released, management plan follows next. Risk factor calculations, project execution plan, alternative listing etc. are the processes conducted in this phase.
5-System Integration Design: This is probably the fifth step of system integration life cycle that includes logical and physical designs created for the system that are to be integrated. Preliminary designs, detailed designs, system tests etc. are the processes included in this phase.
6-Implementation: Once the system design is ready, it is verified and implemented thoroughly. Before deploying the integrated systems, it is tested to give error-free solutions to the customer. In case of errors, integrator verify the system again to make it error-free. The final report consists of the error-free integrated system.
7-Evaluation: This is the last phase where the functioning of the integrated system is checked thoroughly. The evaluation phase includes checking, maintaining, modifying and enhancing the components.
