Question 1:
             The major components of BI are:
a.      Data Warehouse:  A data warehouse is a relational database that is designed for query and analysis. It usually contains historical data derived from transaction data, but it can include data from other sources. It separates analysis workload from transaction workload and enables an organization to consolidate data from several sources.
b.      Business Analytics : It can be defined as  collection of tools  for manipulating, mining and analysing the data in the data warehouse.
c.       Business Performance Management(BPM):   BPM is a set of management and analytic process that enables  management of an organization’s performance to achieve selected goals. It is used for monitoring and analysing  performance.
d.      User interface : User interface is the system by which people interacts with machine . Example: Dashboard
 
The major similarities and differences of DSS and Bi are as follows:
i.                    BI uses data warehouse whereas  DSS can uses any data sources including data warehouses.
ii.                  BI has  a strategy/executive orientation whereas  DSS are normally oriented towards analysts.
iii.                Mostly DSS are built to support decision making directly whereas most BI systems are built to  provide information that will  lead to improved decision making.
iv.                 BI systems tend to be developed with commercially available tools  whereas DSS tend to use more custom programming to deal with problems that may be unstructured.

2.      The Net Present Value(NPV) is  $1215454 which is above 1 million. Therfore the NPV claim made by the consultant is reasonable.
 
3.       
 
Model (DSScode):
 
 

 
 
 
 
 
 
 
 
 
 
 
Output:

 
Table:

 
After processing the model , choosing risk under analysis tab, and selecting  net present  value for  year 2013(npv for other years would make no sense) we get the graph below(choosing cumulative  probabilities).The horizontal axis in the graph below gives the net present value and vertical axis the probability. AS the net present value is  less than $500,000 the proposal should be rejected by the manager.
