Requirements Analysis and Gathering

By the end of this lab, the student will be able to collect, classify, verify, and document functional and nonfunctional requirements.

Task # 1: Identify how the following requirements are incomplete

1. An email notification must be sent to user when he successfully registers into the system.
2. The system will allow salesman to maintain their personal contact manager. When a contact is converted into client then other salesman having duplicate of these contacts in their personal contact manager are informed that they cannot do business with this contact.
3. The installer should check the prerequisites before starting itself.

Answer 1

Here, the task is to identify how the given requirements are incomplete , Lets discuss in detail one by one :

REQUIREMENT -(a) :

An email notification must be sent to user when he successfully registers into the system.

• It can be generally seen that in this modern world of technology it is very easy for the technical frauds and scammers to perform illegal operations and manipulate with the original digital data of the users,which is one of the valuable digital asset to any organization or the company.

• The organizations use these data for various purpose such as for their own prediction of the user demand and interest as well as for the outsourcing purpose. If the data is not secured and is manipulated, it creates distrust with their clients and also hampers the organizations to predict the need and also the quality and efficiency of the product.

• So , the requirement should be like this "An email notification must be sent to the user ,asking for proper authentication of he credentials as well as the device/system authentication, When the user successfully registers into the system. This notification system will help the organization to overcome from from the data manipulation and also from automatic form submissions during the registrations.

REQUIREMENT (b) :

The system will allow salesman to maintain their personal contact manager. When a contact is converted into client then other salesman having duplicate of these contacts in their personal contact manager are informed that they cannot do business with this contact.

• This requirement is incomplete in the manner that it is not sufficient just to inform the other salesman about its contact becoming a client.

• This does not make sure about blocking of the transactions between the two.So there must be two separate list or contact managers for the the two entities i.e normal contacts and clients contacts. the boundary should be well defied between them and the system should make sure that no two-way transactions can be done to maintain the security for the users.

• And whenever a contact s converted into a client , it must be moved from the contacts list to the clients lists and all the previous transactions between the two must be settled before the contact is properly assigned/converted as client.

REQUIREMENT (c) :

The installer should check the prerequisites before starting itself.

• The requirement that the installer should check the prerequisites before starting itself, is incomplete and insecure int the way that the installer should not only check for the prerequisites but also should get verification from the security wall of the system so as to reduce the risk of any further slowdown.

• The given prerequisites check is not sufficient , the installer should also check for any viruses or any data risks associated.since once the installer has performed its operation, the installed system has the control over various segments of the device and this can lead to the data loss as well as the system failure.

• So, the requirement should be "The installer should check for all the pre-requisites as well as check for all the verifications possible from each and every segment of the device before installing ". This will save the device or the system from any type of failure or threat that may come over the period the time.
