3. Problem statement
To Manage the process of building a house from scratch

4. Requirement Specifications
Supported activity list
Human-computer interface description
Solved problem list
Checks and balances
Information source list
Information requesting organization list
Security and fault-tolerant requirements

5. Supported activity list
Allow user to upload the plan
Creates a budget account for each user (like a bank account)
Organize a specific house building process for the user
Scheduling all the construction processes: arranging them in a series (first process; evacuation, second process; lay the foundation, third process; rough plumping…etc.), assigning them to specific start and due dates (first process; evacuation; will take 4 to 5 days)

6. Human-computer interface

7. Solved problem list: Current system: Contains a lot of paperwork
A huge depending on the user's memory
The user is TOO involved in the process
Time consuming
Not strict
New system:
No paper work
No depending on the user's memory
The system does most of the work
A precise system with no mistakes
A strict system;

8. Use Cases - Possible Use cases
Use cases are the steps and procedures between the user and the system and we will define three possible use cases.
- Possible Use cases
create an account
Upload a plan and start constructing
Checking for each process.

9. Use case Description Upload a plan and start constructing
The system will create a schedule for the User to organize time and shows the possible materials
Pre-condition
Primary flow of event
Alternate flow of event
Post-condition

10. Use case Description Checking for each process.
The system will make sure that the User is on the right track and there is no delay in processing.
Pre-condition
Primary flow of event
Alternate flow of event
Post-condition

11. Formal scenarios Scenario 1: (Room Design)
Our system will give the option of having a 3D MAX view of the AutoCAD plan for the user to design any room before buying the furniture

12. Formal scenarios Scenario 2: (Ordering Materials)
The user chooses the needed materials that the system will display from different manufactures

22. Class Skeletons - Public class users {} class role:
this class manages the users; their accounts, and their budgets
- Public class Materials {}
this class manages the materials; their information, adds materials, removes materials
