2. Propose at least five (5) system capabilities for the company.
Provide a rationale for your proposals.
a. Tracks and retrieves details such as customer particulars and
information of each order. Assign a unique code to each
transaction as its key attribute that can be tracked. Create a new
entry to every new customer in the database whereas existing
customers are sorted according to attributed transaction code.
b. Calculates the profit/loss margin of single transactions by

And daily profit and loss reports are produced immediately at
the end of the day, efficiency and accurately.
c. Builds a customer database to assists marketing to preparing
special mailings and sales. That is based on a report that
generated by complex searches, which are conducted by
returning results of existing transactions and match the keyword
in the database.
d. Programmed to create specific reports such as periodic sales
reports or list of outstanding accounts, even consume behaviors
analysis or sales trend predict when such reports are needed.
3. e. Elaborates on credit balances and aged accounts of each
customer in detail to determine the reason even resolve high
balance of account receivables.
f. Distributes notice letters and credit history reports to
customers with outstanding account receivables.
3. Ascertain the three (3) possible scenarios in this new direct
sales and accounting system.
According to the textbook, scenario describe an instance of a
use case, and represents the flows of a set of activities within a
use case (Satzinger, Jackson & Burd, 2012, p. 121). It's very
useful for system analysts and designer to understand what the
user is trying to do and what they need. There are three
scenarios of Especially for You Jewelers company's new direct
sales and accounting system which demonstrate three unique
path of activities to accomplish a task.
Scenario one: Inventory replenishment. The marketing
department has the responsibility to replenish the inventory
routinely. Every time before they place the order to purchase
products from vendor, the marketing department would check
the inventory status and request a sales trend report as
references to determine what products need to be purchased.
After the vendor or supplier received the orders, they start to
prepare and then deliver the merchandise. When the new
merchandise arrived, they will be stocked. And then the stock
will update the inventory database.
Scenario two: Payment fulfillment. When a customer initiates a
checkout process, the accounting department will receive the
request. The accounting department then going to retrieve the
customer's account information from the CRM database to
determine if this customer could pay the bill by credit or cash
only. Which is expected a method to reduce the account
receivable. Meanwhile, the accounting department also going to
check if this customer is eligible for some promotion. Then the
4. total amount of the payment will be calculated and offered to
the customer.
Scenario three: Promotion (special mail). When the marketing
department proposes to initiate a promotion which is mail
exclusively in order to increase repeat sales to existing
customers, they need some information from two sources. One
is the sales trend report, another one is a list of eligible
customers' accounts, which is retrieved from the CRM database.
If the inventory of involved products that according to the sales
trend report is not sufficient, the replenishment should be took
place before the promotion campaign be launched.
4. Using Microsoft Visio or an open source alternative such as
Dia, develop an activity diagram for each scenario that you have
identified. Note: The graphically depicted solution may not
exceed one (1) page per diagram. Provide a narrative that gives
an overview of your diagram.
Activity diagram is basically a flow chart that be used to
demonstrates the sequence of activities. Activity diagrams
describe parallel and conditional activities, use cases and
system functions at a detailed level, and useful for business
(Sparxsystems, 2015).
These three activity diagrams for scenarios that mentioned
previously are show as below:
Figure 4.1 is an activity diagram about inventory replenishment.
As the diagram shows, marketing send a query to inventory and
sales separately, and then makes a decision if it is necessary to
replenishment according to the feedbacks of inventory and
sales. If there are some demands exist, then the marketing place
an order to the vendor. The stock will receive the merchandise
and updates the inventory after the vendor prepared and
delivered the products.
Figure 4.2 is an activity diagram about apayment procession of
a customer’s order. When a customer needs to checkout, the
accounting will check the CRM database for the customer’s
5. credit to determine available payment methods, and check if
there are any available promotion to offer a discount. Then the
bill will be calculated and passed to the customer. After the
customer payed the bill, the payment is completed.
Figure 4.1
Figure 4.3 is an activity diagram about mail exclusively
promotion. When the marketing designs a mail exclusively
promotion, the marketing will ask sales for sales trend report as
a reference and query a name list of eligible customers from
CRM database. And then invoke an inventory replenishment if
inventory reports it is needed. Then marketing send out the
promotion mails generated by system.

company and the system's functional capabilities (IBM, 2015).
The system vision document of the new direct sales and
accounting system of Especially for You Jewelers is developed
as follow.
System vision document
Direct sales and accounting system of Especially for You
Jewelers
Introduction
Especially for You Jewelers has experienced a tremendous
increase in its business over the last couple of years. As a side
effect, a lot of problems, such as high balance of account
receivable or sales cannot be tracked sufficiently, arising and
cannot be solved because of the current system lack of the
capability.
10. In order to solve exist problems and improve the business
performance, Especially for You Jewelers has the urge to
develop a direct sales and accounting system.
Business requirements
The Business requirements of Especially for You Jewelers
include following aspects:
i. Track every sales to determine where is the profits come from
ii. Track every sale to discover the reason why the account
receivables so high and find a way to reduces it
iii. Develop a customer database to manage customer
relationship
iv. Analyze the data stored in the database to know the sales
trend
v. Analyze the data to learn the consume pattern or customers
vi. Combine the results or sales trend analysis and customers'
consume pattern analysis to adjusts inventory and initiates
promotion campaign
System overview & Major features
The direct sales and accounting system is comprised of several
subsystems, which are Customer Service subsystem (contain a
CRM database), Marketing subsystem, Sales subsystem, Product
Information subsystem, Accounting Information subsystem and
Supplier Information subsystem.
Since Especially for You Jewelers is in a period of business
boosting, there are many explicit requirements, though, new
11. requirement keep appearing like the problems they faced.
Therefore, the system is going to be developed by adaptive
approach. Through many times iteration, the agile methodology
could develop a prototype system rapidly to produce business
value early. The increment requirements could be add to the
system in next iterations.
The system is developed as a web-based system because its
feature of platform independent makes it easy to be access from
anywhere, any devices. Users don't need any installations or
upgrades, which makes this system maintenance easier (Revsys,
2015).
The CRM database is based on relational database, the data
structure is simple and easy for database users to understand
and use.
The authorization and privilege control mechanisms in an
RDBMS based on the types of database tasks the users need to
perform. Which makes database administration more secure and
easier (Deborah, 2015).
In addition to fulfill the exist requirements, new system is able
to provide the capability of decision making support by data
analysis.
Scope and limitations
According to the business model of Especially for You
Jewelers, the new system focuses on its traditional brick-and-
mortar business. E-commercial is not take into account by now.
Other needs
Since the new system is web-based and developed by agile
approach, once there are any motivate that drive Especially for
You Jewelers to expand online business, it is much easier to add
12. increment requirements than develop another new system.

Technical Paper: Final Project Plan
Due Week 10 and worth 200 points
Especially for You Jewelers is a small jewelry company in a
college town. Over the last couple of years, it has experienced a
tremendous increase in its business. However, its financial
performance has not kept pace with its growth. The current
system, which is partly manual and partly automated, doesn’t
track accounts receivables sufficiently, and the company is
finding it difficult to determine the reasons why the receivables
are so high. The company runs frequent specials to attract
customers but has no idea whether these efforts are profitable or
if the benefit—if there is one—comes from associated sales.
Especially for You Jewelers wants to increase repeat sales to its
existing customers; thus, it needs to develop a customer
database. It also wants to install a new direct sales and
16. accounting system to help solve the outlined problems.
The new direct sales and accounting system for Especially for
You Jewelers will be an important element in the growth and
success of the jewelry company. The direct sales portion must
track every sale, be able to link to the inventory system for cost
data, and provide a daily profit and loss report. The customer
database must be able to produce purchase histories to assist
management in preparing special mailings and special sales to
existing customers. Detailed credit balances and aged accounts
for each customer would help to solve the problem with the high
balance of accounts receivables. Special notice letters and credit
history reports would help management reduce accounts
receivable.

1. Suggest at least five (5) expected business benefits that
Especially for You Jewelers company might derive from a new
system. Provide a rationale for your suggestions.
