Ridgeline Mountain Outfitters
(RMO): background/problems



RMO has a disparate collection of computers
dispersed across home offices, retail stores,
telephone centers, order fulfillment/shipping
centers, and warehouses- everything connected
by a complex set of LAN’s, WAN’s and VPN’s
A new Consolidated Sales and Marketing
System was proposed
This is a major project that grew out of the RMO
strategic planning process

RMO Existing Application
Architecture

Supply Chain Management (SCM)


Phone/Mail Order System



12 years old; Visual Studio/MS SQL
Reached capacity; minimal integration
Retail Store System


5 years old; Java/Oracle
Older package solution; minimal integration
Customer Support System (CSS)

Web based system; evolved over the years, minimal
integration

Ridgeline Mountain Outfitters
(RMO): solution



Strategic planning and competitive advantage
for organizations involves leveraging information
systems
The information systems strategic plan is
based on the overall strategic needs of the
organization
The information systems strategic plan includes
definition of the technology architecture and
the application architecture needed by the
organization
4
Information Systems Strategic
Plan


Technology architecture— the set of
computing hardware, network hardware and
topology, and system software employed by the
organization
Application architecture—the information
systems that supports the organization
(information systems, subsystems, and
supporting technology)
5
Proposed Application Architecture:
Integrate SCM and New CSMS
6
New Consolidated Sales and
Marketing System (CSMS)

Sales Subsystem


Order Fulfillment Subsystem


Track shipments, rate products and services
Customer Account Subsystem


Integrates online, phone, and retail stores
Shopping history, linkups, “mountain bucks” rewards
Marketing Subsystem

Promotional packages, partner relationships, more
complete merchandise information and reporting

Support mobile computing devices
Incorporating customer’s feedback and
comments into production information
Integrating social networking functions




Support smartphones
Tablet computers
Designed for each platform and downloadable
apps
Mining from Facebook and Twitter

What is the problem and idea for the solution?
What are the capabilities the new system will have?
Helps define the scope
Business Benefits

13. What is the difference between system
capabilities and business benefits?



The business benefits are measured in the
dollars that are brought to the organization,
either as increased revenue or reduced costs.
(Intangible benefits are those where a dollar
amount cannot be easily assigned, but still will
add value to the organization.)
The system capabilities are the functions that
support the business procedures.
The system capabilities are those things that
enable or lead to the business benefits.
15
15. List 10 types of benefits that may be
considered when approving a project.


Opening up new markets with new services, products, or locations
Increasing market share in existing markets
Enhancing cross-sales capabilities with existing customers
Reducing staff by automating manual functions or increasing
efficiency
Decreasing operating expenses, such as shipping charges for
“emergency shipments”
Reducing error rates through automated editing or validation
Reducing bad accounts or bad credit losses
Reducing inventory or merchandise losses through tighter controls
Collecting receivables (accounts receivable) more rapidly

3. Develop a System Vision Document for Especially for You
Jewelers based on the work you did for Problem 1 and
Problem 2.
19
Activities of Core Process 2:
Plan and Monitor the Project
20
Schedule the Work

Project manager must establish initial project
schedule and keep adjusting:

Project Iteration Schedule


The list of iterations and use cases or user stories assigned to
each iteration
Detailed Work Schedule



Within an iteration, the schedule that lists, organizes, and
describes the dependencies of the detailed work tasks
As each iteration is finished, a detailed work schedule is
prepared for the next iteration
The next detailed work schedule takes into account the
changes necessary based on feedback/progress
21
21. What is the difference between the project iteration
schedule and the detailed work schedule?
22
6. What is meant by an organic approach?


The way a plant or animal grows is an organic
approach. It starts small and increases in size.
But even when it is small it still has all the
essential components and is fully functional.
As it grows it develops more capability and
expands its scope.
Developing a piece of software “organically”
attempts to take a similar approach. It starts
small, but is functional, and grows piece by
piece adding more capability.

Problem 8: Project Iteration
schedule



Currently, the university has very sparse records of its equipment
and almost no records about maintenance or the software that has
been purchased.
A list of use cases has been defined; it will serve as the starting
point to develop this system.
Take the following list of use cases to create a project iteration
schedule. You should try to arrange the use cases so similar ones
are developed together. Also, the most important use cases should
be developed first
