  • Internal Partnerships
  • Supplier Management
  • Architecture and Standards
  • Human Resource Management
anticipating new technologies
Anticipating New Technologies…
  • Business and IS staff must work closely to evaluate which technologies can best advance the business strategy.
  • It is the job of the IS department to scout new technology trends and help the business integrate them into planning and operations in terms of the following 
what is doesn t do
What IS doesn’t do…
  • There is still a need for management to partner with IS to make sure business goals and needs are met.
  • General managers generally set the business strategy, not IS professionals.
  • Since the 1970s, IT managers have turned to outsourcing as an important weapon in the battle to control costs.
  • Outsourcing means the purchase of a good or service that was previously provided internally – with IT outsourcing an outside vendor provides IT services traditionally provided by the internal MIS department.
  • Over the years, however, motives for outsourcing have changed.
factors driving outsourcing
Factors driving outsourcing
  • Cost savings
  • Qualified IT staff are difficult to find and retain
  • By bringing in outside expertise, management needs to focus less on IS operations and more on the information itself.
  • Outsourcers are specialists, should understand how to manage IS staff more effectively.
  • Outsourcers may have larger IS resources that provide greater capacity on demand.
  • Outsourcing can help a company overcome inertia to consolidate data centers that could not be consolidated by an internal group, or following a merger or acquisition.
avoiding outsourcing pitfalls
Avoiding Outsourcing Pitfalls
  • Don’t focus solely on price
  • Use life-cycle service contracts that occur in stages
  • Establish short-term supplier contracts
  • Use multiple, best of breed suppliers
  • Develop skills in contract management
  • Thoroughly evaluate outsourcers capabilities
  • Choose an outsourcer whose capabilities complement yours.
  • Base choice on a cultural fit as well as expertise
  • Determine if outsourcing relationship produces a net benefit for your company
centralized vs decentralized organizational structures
Centralized vs. Decentralized Organizational Structures
  • Centralized: reduces duplication since resources under one control and, often, in one location.
  • Decentralized: creates flexibility because resources not in the same location or control
  • “Federalism” combines centralization with decentralization.
  • For example:
    • Bethlehem Steel allows major business units (plants) to decentralize and operate independently while
    • Levi-Strauss centralized to minimize the duplication of resources and save on costs.
centralized vs decentralized approaches
Centralized vs. Decentralized Approaches
  • Bethlehem Steel has taken a decentralized approach, which mirrors their decentralized business strategy as its managers believed that computing power and decision-making should be located within local business units
  • Levi Strauss adopted a centralized strategy as it wanted to gain better control over strategic IT resources, minimize duplication across its business, and maximize sharing of scarce resources
how does the management of it differ when the scope is global rather than local
How does the management of IT differ when the scope is global, rather than local?
  • Large global MIS organizations face many of the same organizational issues as any other global department.
  • For IS, a number of issues arise that put the business at risk beyond the typical global considerations. Table 8.12 summarizes how a global IT perspective affects six information management issues.
going offshore for is development
Going Offshore for IS Development
  • Countries such as India, the Philippines, etc, offer “offshoring”,an alternative to in-house systems development
  • Many Indian enterprises, for example, are well known for their use of the Capability Maturity Model (CMM) Level 5 software development processes, making them extremely reliable, and ultimately desirable as vendors
  • The types of tasks that are outsourced are usually those that can be well-specified
  • It raises the issue of what to send offshore, and what to keep within your enterprise MIS organization.
offshoring problems
Offshoring Problems

Companies engaged in or considering offshoring express concern about …

  • quality of the work performed,
  • unexpected costs, and
  • project delays
  • future maintenance
  • not developing skills in-house
extreme programming xp
Extreme Programming (XP)
  • A disciplined approach to software development
  • Good for risky projects with dynamic requirements
  • Emphasizes customer involvement and teamwork
  • Deliver software to customer asap and implement changes as suggested
when to use xp
When to Use XP
  • When customer does not have firm idea of requirements
  • When functionality is expected to change in short-term
  • When the time-line is compressed and risk is higher
the xp approach
The XP Approach
  • Set up for small teams of programmers – between 2 and 12
  • Cannot use XP on a project with a huge staff
  • Must be able to create automated unit and functional tests
  • User stories
  • Paired-programming
  • Small releases
the xp team
The XP Team
  • Developers (work in pairs)
  • Managers
  • Customers
xp user stories
XP: User Stories
  • Customers create stories to describe functionality needed
  • Drive creation of acceptance tests for verification
  • Developers estimate how long each story will take to implement
xp release planning meetings
XP: Release Planning Meetings
  • RPM used to create a release plan
  • Release plan used to create iteration plans
  • Project velocity = estimates of user stories completed in the last iteration
xp iteration planning
XP: Iteration Planning
  • Each iteration is 1 – 3 weeks long
  • User stories are broken down into programming tasks
  • Each task should be 1 – 3 days in duration
  • Use project velocity to determine if the iteration is overbooked
  • Adds agility to the process
xp lessons learned
XP: Lessons Learned
  • Customer is always available
  • Move people around
  • Avoid adding unnecessary functionality
  • Follow coding standards
network security
Network Security
  • SSL – the Web standard
  • SET – a consortia standard favored by financial institutions
  • Digital signatures – provide authenticity
  • Firewalls – come in different flavors
  • Secure Sockets Layer, a protocol developed by Netscape for transmitting private documents via the Internet.
  • SSL works by using a private key to encrypt data that's transferred over the SSL connection. Both Netscape Navigator and Internet Explorer support SSL, and many Web sites use the protocol to obtain confidential user information, such as credit card numbers.
  • By convention, URLs that require an SSL connection start with https: instead of http:.
  • Supports non-repudiation for merchant only!
  • Secure Electronic Transaction, a standard that will enable secure credit card transactions on the Internet. SET has been endorsed by virtually all the major players in the electronic commerce arena, including Microsoft, Netscape, Visa, and Mastercard.
  • By employing digital signatures, SET will enable merchants to verify that buyers are who they claim to be. And it will protect buyers by providing a mechanism for their credit card number to be transferred directly to the credit card issuer for verification and billing without the merchant being able to see the number.
  • Supports non-repudiation for both buyer and merchant
  • Combine software and hardware
  • Normally between LANs and WANs
  • Can reside between LANs
  • May only check header information
  • May check content
  • Can take time to configure
  • Can slow down network
  • Can be assigned to one or multiple ports
