A zoo is in the process of introducing a new IT system to improve its processes and drive greater efficiency in its operations. It has received permission from the board of directors for a phased approach to introduce new business functionality and to replace manual processes with digital solutions.
The key areas for inclusion in the first phase are a new animal health monitoring system, which will allow the zookeepers to utilize the power of data analytics to monitor and proactively manage the health of the animals.
It will also provide them with a way of accurately recording the birth of new animals and record loans of animals to other zoos around the world.
On the public-facing side, the project will provide customers with an adoption scheme, which will raise much-needed funds.
