Requirement Analysis

Software Statement of Scope

The system must have an inventory listing with thumbnails (optional) security option for warehouse security. It must have a stocking and delivery scheduling manager to allocate for stock that being transported within the warehouse. It also should be able to inform user of stock location and space availability, and also maintain a database of supplier and customers. Bar code reading should be incorporated for easy stock identifying purposes. The user must also be able to obtain goods movement summaries (goods delivered, goods arrived).

Refined Software Statement of Scope

We feel that the requirements that given by our client is not sufficient enough to give us a description about the software the they want us to implement, therefore we discuss and clarify some points that we have in doubt with. After brainstorming with our client, finally they come out with more detail and concise requirements, which is : 

The system must have an inventory listing with thumbnails (optional) security option for warehouse security, which requires the user to provide a password first (logon and logoff) before they can do further transaction. It must have a stocking and delivery scheduling manager to allocate time slot for stock that being transported within the warehouse and the schedule for the goods movement transaction within the warehouse. It also should be able to inform user of stock location and space availability, and also maintain a database of supplier and customers. Bar code reading should be incorporated for easy stock identifying purposes. The user must also be able to obtain goods movement summaries (which contain date, type and quantity of transaction, goods delivered and goods arrived).

Requirement Analysis

Requirement analysis is first done by performing grammatical parse; extracting the verbs and nouns. The nouns chosen will become the potential classes / objects, and the verbs will become the potential services/methods.

Grammatical Parsing

The system must have an inventory listing with thumbnails (optional) security option for warehouse security, which requires the user to provide a password first (logon and logout) before they can do further transaction. It must have a stocking and delivery scheduling manager to allocate time slot for stock that being transported within the warehouse and the schedule for the goods movement transaction within the warehouse. It also should be able to inform user of stock location and space availability, and also maintain a database of supplier and customers. Bar code reading should be incorporated for easy stock identifying purposes. The user must also be able to obtain goods movement summaries (which contain date, type and quantity of transaction, goods delivered and goods arrived).

Potential List

There are six categories for a noun to be considered as potential class / object:

• External entity: people, things, devices or systems that lie outside the scope of software system.
• Things/occurrence remembered: items of information and events that must be observed and recorded by the system.
• Sites: location, place, or environment that the system being analyzed needs knowledge of.
• Organizational units: the department, division, organization that the system needs to keep the information about.
• Structures: general-specification (GS) / whole part (WP).
• Roles played: there are two types of roles: the roles representing users of the system and the roles representing people who do not interact directly with the system, but whose information is remembered.

The potential nouns from the requirement can be listed in the potential list as shown below:

 Confirmed / Rejected List

Next step to do is to confirm of objects and classes from the potential list. Confirmation is done based mainly on the three categories as follows: 

• Needed remembrance: determine whether knowledge about the item is of interest to the system being analyzed.
• Needed services: determine whether the potential class / object needs to provide some form of processing / services. As long as there is needed remembrance, there will be needed services provided.
• Multiple attributes: if a potential object / class has only one attribute, then the “object” is more suitable as an attribute of one or more of the other objects and/or classes in the list.

Based on the potential list above, we can now proceed to the confirmation of the classes / objects, as listed in the confirmed / rejected list below:
