System integration ensures that all systems and software programs work together.
System Integration (SI) is the process of implementing new systems that interface with existing systems. It applies to all human disciplines, simple or complicated. IS requires a lot of planning, implementation and optimization. Software system integration, management system integration, and business system integration are examples of IS.
The basic purpose of IS is to solve problems. Without the SI, there will only be solutions that can cause more problems. System integrators are experts in various disciplines such as finance, technology, engineering and management.
Software system integration (SSI) often starts with defining existing systems or solutions. If the existing solution uses outdated technology, SSI will propose a new system based on currently available improvements over the existing solution. In general, the resources used in creating new systems are justified by financial experts, presenting the savings or increase in revenue for implementing the proposed solution.
Management system integration (MSI) identifies existing solutions and proposes new solutions that would exploit the opportunities. For example, when wireless technology brought computing power to people in the field, the response time to resolve a new action was greatly reduced. New developments in software and communication technology allow people to reduce the time needed to brainstorm and make decisions.
Systems integration as a business will always have enormous potential. Any customer who needs to optimize any aspect of their operation may need help from people in the IS business. The IS process usually starts with a request for proposal (RFP) from the customer. For example, if the customer is a company’s security department, the RFP might define existing issues experienced by security personnel.
A solutions company then submits a proposal. The proposal includes definitions of existing problems as well as proposed solutions. For an RFP that emphasizes the need to strengthen nighttime security, for example, the proposal could include closed-circuit night-vision television (CCTV) cameras. The cost aspect is taken into account when proposing solutions within the client’s budget.
Systems integration can involve any type of system that implements a solution, and the solution must have measurable returns. When the proposed system can save expenses or help generate revenue, the system is evaluated based on other benefits and risks. For example, nuclear energy is mainly harnessed because of the very low cost per unit of energy, but there is a risk of radioactive contamination, which is harmful to people and the environment.
