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 LANs, WANs and VPNs
• 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)
• 5 years old Java/Oracle
• Phone/Mail Order System
• 12 years old Visual Studio/MS SQL
• Reached capacity minimal integration
• Retail Store System
• 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

5
Information Systems Strategic Plan

• Technology architecture the set of computing
  hardware, network hardware and topology, and
  system software employed by the organization
• Application architecturethe information systems
  that supports the organization (information
  systems, subsystems, and supporting technology)

Proposed Application Architecture Integrate SCM
and New CSMS

New Consolidated Sales and Marketing System (CSMS)

• Sales Subsystem
• Integrates online, phone, and retail stores
• Order Fulfillment Subsystem
• Track shipments, rate products and services
• Customer Account Subsystem
• Shopping history, linkups, mountain bucks
  rewards
• Marketing Subsystem
• Promotional packages, partner relationships, more
  complete merchandise information and reporting

Key Additions

• Support mobile computing devices
• Incorporating customers 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

Activities of Core Process 1Identify Problem
and Obtain Approval

Identify the Problem

• System Vision Document
• Problem Description
• What is the problem and idea for the solution?
• System Capabilities
• What are the capabilities the new system will
  have?
• Helps define the scope
• Business Benefits
• The benefits that accrue to the organization
• Tangible (in dollars) and intangible 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.

16
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

Especially for You Jewelers based on the work you
did for Problem 1 and Problem 2.

Activities of Core Process 2Plan and Monitor
the Project
21
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

22
21. What is the difference between the project
iteration schedule and the detailed work
schedule?
23
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.

24
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
