In school I realised that I was never certain on what to eat in school, because I never knew what the school was planning on having for the next day. As my I was looking for a Computer Science IA, the idea of solving the problem for my lunch schedule was ideal. The students have to know the evening before hand what they are going to eat. If they would get informed a day before, they could decide whether they want to eat in school or bring their own food from home.
The idea of a telegram chatbot came to my mind as it is an automation system and can therefore be used to send respond messages to the students and inform them about the meal. The bot will also have a tool to communicate with the kitchen staff to ensure safe organisation. Students will have the option to choose in the chat conversation and the bot will inform the kitchen on how many meal items to prepare for the next days meal.
Cook and cafeteria owner change their meal plan everyday and present them in the caffetitria. Students and staff therefore don't know what they're about to have for lunch. This results in fewer meals being purchased because they do not know whether they should bring money or home-made lunch instead. As the cooks can now tell more precicly how much food is demanded, they can reduce their waste of food.
In addition to that it'd be useful being informed in case of sold out meals or changes in menu.
- The evidence of consultation has been referred to in the scenario.
- Any documentation associated with evidence of consultation has been linked to the cover page.
An application that helps informing students and staff on a daily basis (~6:30 and 7:30 in the morning) about the upcoming meals that day. The application can be configured in advance for the upcoming meals of the week / month.
Optional: an interaction between the recipients of the information and their preferred choice for the upcoming meal could be made.
