2 Problem Analysis
3 System analysis
The Norfolk hotel do not have a reservation system and still use the manual process to conduct their business processes.
our Investigation will involve use of techniques such as observation, interviews, samples and document revisions.
The Norfolk hotel offers many services and therefore since it is assumed that the operations are manual problems will include;
Difficulty in location of guest files due to the large number of guests’ files.
Large storage space required due to the fact that the physical files occupy too much space.
Human and computational errors due to the fact that humans are prone to make mistakes.
Excessive complains from guests because of poor management of documents encouraged by the manual system.
Poor communication since guests may often be served with services they haven’t ordered.
Difficulty in data analysis where accountants may find it difficult to analyze the guests’ data during generation of expenditure bills.
Project managment tool that will be used is the Microsoft project manager since it is readily available.
This tool is important because it helps to identify upcoming development projects that arose from problems, opportunities and directives.
Involves identification and articulation of system requirements where all the requirements should be identified to avoid future problems, constrains and interruptions. The stage also involves seeking out and valuing the input of all the stakeholders. This stage helps in identifying system input details and also system output details.

DECISION ANALYSIS PHASE
Is characterised by Feasibility Analysis.
Investigation is required in this stage to determine whether or not a given project is feasible. As per the Norfolk hotel, four main areas will be considered. This included the technical aspect, financial aspect, organizational aspect and the schedule aspect.
After acquiring results from the definition phase, system architecture is used to create the overall structure of the system. The system design phase describes the functional capabilities of the proposed system.
Analyst plans smooth conversion from old system to new system
Review and evaluate system
In a dynamic context, organizations need to be compelled to carry out new competitions and to possess an in and out cosmo vision for themselves.
strategic management tools are required. One of the strategic tools is an information system which involves computer technology.
For the system to function to its best capability, the analyst recommends the following:
Networking of the hotel’s computers to enable data communication at the hotel.
The hotel server be connected to the internet. In addition the hotel should have a web site onto which the booking page will be loaded to enable online booking over the internet.
The system should be troubleshoot and updated to maintain the high competence standards of the system. This is because, being a system, the NORFOLK HOTEL MANAGEMENT SYSTEM is bound to undergo system entropy.
High security measures should be upheld in order to avoid theft crimes at the hotel.
The latest versions of antivirus be installed and updated frequently in order to detect the many virus programs that are emerging daily in the IT society.
Every employee of the hotel is identified uniquely by a user name and password to his/her office computer. As in 1980 terrorist attack
