Bardens Bakery System Investigation

Question: Following on from any possible incorrect orders: If an order is received in the afternoon say, then the order would be raised manually, i.e. input by hand.
Answer: There is a lot of paperwork associated with this process. Lots of problems with this current system, therefore there it is hoped that new information system can solve [there could be human errors in the ‘manual order’ process].
Question: How does the delivery process work
Answer: Each delivery is dispatched the following day.
Answer to Part 2 – SYNOPSIS AND EVALUATION
Answer to section 1:
The purpose of functional decomposition is to iteratively break down the description of the system into finer detail which creates a set of charts in which one process on a given chart is explained in greater detail on another chart.
Each process may consist of several sub processes. Each sub processes may also be broken down into smaller units. Decomposition continues until you have reached the point where no sub process can logically be broken down any further.
A good Functional Decomposition helps the analysis in several ways:

The simplicity of the structure and representation aids in understanding the breakdown of functions and processes.
Specifying the precise requirements and features for each function becomes easier because the functions and processes are broken down into smaller units.
The partitioning and independence of the functions localizes errors and minimizes system faults.
It allows the customer to view and discuss the organization in a form that can be dealt with, i.e., as a collection of functions, rather than as a continuous process.
The process of decomposing the functional requirements is as follows:

The above process starts with the primary function of the company and breaks down to the services it provides and the granular level of decomposition is shown to give a picture of all the processes involved and sub processes that are carried on.
The preparation for the interview demanded a lot of knowledge of the back ground of the company processes and it required a detailed study of the various processes which are carried on. The inflows, outflows and the various data structures, for example the databases involved.
The overall conduct was good. Working within a team led to the identification of facts and better understanding the penetrations of the system and the decision as to how many data flows are involved.
