ROLES OF SYSTEM INTEGRATOR Vertical Integration System Integrators is a professional or company that focuses on connecting various systems within combines different technology components, a specific department or business function software, or systems into a single, unified solution. within an organization. They ensure that all parts work together smoothly, Point-to-point Integration improving efficiency, reliability, and functionality for where individual systems are directly businesses or organization. connected to share data or functionalities Why System Integrator are important they need to work together. Boost Efficiency They connect different parts Horizontal Integration of a business, so data and information can It brings together functionalities and data from flow easily, saving time and reducing manual different departments within an organization, work breaking down departmental silos and Save Money By bringing separate systems fostering a more unified view of operations together, they cut down on the cost of having Application Programming Interfaces too many individual tools and processes. provides a layer between one application and Improve Reliability With everything working another, creating a common language that as one system, there are fewer errors and these applications can use to speak to each fewer technical problems other. Enable Innovation They allow businesses to Middleware add new technology without needing to This is a “hidden” layer of software that brings replace everything that already works systems and applications under a single tent. Support Growth As a business grows, system It provides common services and capabilities integrators make it easier to expand without to applications beyond what the operating major disruptions system offers. Key Roles of System Integrator Webhooks System integrators are the architects and engineers Commonly used in SaaS, webhooks link of the digital world. They bring together a blend of applications through event-based solutions. technical expertise, business acumen, and problem Webhooks provide real time information, but solving skills for better integration of a system they’re limited to sending an event. Electronic Data Interchange Testing & Deployment: Before going live, EDI’s replace paper documents with a they'll rigorously test the integrated system to standardized electronic format. These are ensure everything works as planned. Then, typically done through a value added network they'll deploy the solution, either all at once or through a third-party network or directly in phases, depending on your needs through the Internet Maintenance & Support Systems integrators need to have a deep understanding of WHY DO WE NEED SYSTEM INTEGRATION? interface layers, subsystems, and common Having these types of system integration improves data. They also need to have experience with efficiency and productivity. technologies and strong business knowledge Integrating systems reduces the need for repetitive manual data entry, as information flows automatically between connected systems. This streamlining minimizes the chances of human error and speeds up business processes, helping System Integrator Required Skills STEPS OF SYSTEM INTEGRATION Technical proficiency Systems integrators need to be proficient in software technologies, Step 1 Gathering information and planning automation equipment, and material including requirements and expectations. This handling. They also need to know how to means listing all of the systems that need to be design computer networks and access integrated and researching the best method of requirements. integration for each one. This outline should Problem-solving Systems integrators need to mention any operations, business processes, or be able to solve problems and have an open insights that the company wishes to improve. mind. They should also be able to accept Step 2 Analysis of the gathered information criticism This is a deeper dive into planning and involves Project management Systems integrators laying out all the steps and structure of the need to be able to collaborate, solve integration. The goal of this step is to determine problems, and produce results while adhering operational feasibility of designing software that to time restrictions and financial guidelines will adequately address all of the concerns.

The most typical one involved in the processes that the integrated systems of these is the internal IT department. The IT handle. People who do not know or understand the department sometimes tends to forget its role as a business processes involved can very easily merely support organization, and it wants to act as the driver overlook extremely important details regarding the for the integration.
