please any help

For the following system, (i) formulate a value proposition and a consumer segment; (ii) draw a use case diagram with all the use cases; (iii) write the complete description of one of the use cases; (iv) write a use story; (v) draw a UML class diagram. A politician hired you to develop a management system for her daily life. She wants her secretary to deliver her the morning agenda every day, including the pending tasks and anniversaries. For each appointment, she wants to know the date, time, duration, location, description, participants, suit (whose pre-registered values are sports, informal, social, and back-tie). While the appointment is being registered, if the place is not registered, it can be registered at that moment. The appointments can be lunches, audiences, cafes, ceremonies, cocktails, interviews, dinners, meetings, visits, or others. Several people (who must be previously registered) can participate in an appointment. For all registered people, their name, telephone number, cell phone number, occupation, e-mail address, and, optionally, their address must be informed. If the politician cannot participate in an appointment, she can delegate it to one or more of her advisors. As soon as the politician delegates the appointment, the advisors receive an SMS on their cell phone telling them. The politician can also get a report with all the appointments of an advisor. Travel must also be registered in this system. For each trip, the start and end dates, the description, the advisors that will accompany, and the necessary documentation must be recorded. Some tasks are pre-registered in the system, for example, purchase of passage, lodging, speech, transportation, visa, gift purchase, sending confirmation, etc. When registering a trip, the secretary selects the tasks that apply to that trip and indicates the person responsible (an advisor) and the deadline. Ordinary tasks are also registered in the system. For each task, the description, the person responsible (an advisor), the deadline, the priority (whose pre-registered values are low, medium, high, and urgent) are registered. The politician can modify the list of priorities at any time. The events (holidays, celebrations, such as the day of each profession, etc.) should also be registered because the politician wants to send an email to all the professionals whose day is being celebrated. For example, on a teacher's day, she wants to send a message to all registered teachers.
