API development to improve integration and resource efficiency. : Decreasing user interactions and automating verification processes of information between applications.

Companies today often have a variety of applications used in the daily work. The problem that companies face with these applications is that they often are brought in to deal with a specific task, and they are often brought in at different times by different third-party developers. This results in the applications being independent units and integrates poor with each other, making work and maintenance with the applications inefficient. To improve efficiency the applications need better integration with each other. Better integration can be achieved by either replacing the current applications with a new software or develop a software that helps the applications communicate. This project covers the development of the later, an API to improve the efficiency at Volvo Construction Equipment in Braa ̊s. The API is developed with the Enterprise Service Bus (ESB) as inspiration. The purpose of the ESB is to act as a middleware for the applications. Due to time limitations for the project integration between the applications wasn’t achieved. Instead, the focus was set on improving one of the moments in the work process at Volvo, that is verifying information between applications. The verification is today done manually which makes it time-consuming and this is the API set out to deal with. The API results in a reduction and improvement regarding the verification. The API still needs a manual input of data from the applications, but the API has automated the verification of the information between the applications resulting in hours of reduced work for the staff at Volvo
