Poppy Pet Care Kennels offers short-term accommodation for dogs whilst their owners are on holiday. The managing director of the company has initiated a project to create a new website that will allow owners to view kennel availability, book kennel accommodation and allow them to monitor their dogs whilst they are away, via a webcam.
The system will also allow kennel assistants to plan the dogs' feeding times and schedule kennel maintenance.
Customers will be able to leave feedback on the website, which will be reviewed by the quality manager who may respond to comments made by the customer.
