CHAPTER 4:MEASURING THE SUCCESS OF STRATEGIC INITIATIVES




           measuring information technology success         


  •  Key performance indicator - measures that are tied to business drivers.
  •  Metrics are detailed measures that feed KPIs.
  •  Performance metrics fall into the nebulous area of business intelligence that is neither technology, nor business centered, but requires input from both IT and business professionals.



               EfFiCiEnCy AnD EfFeCTiVeNeSs:-


>Efficiency IT metric - measure the performance of the IT system itself including throughout speed and availability.

 >Effectiveness IT metric - measures the impact IT has on business processes  and activities including customers satisfaction conversion rates and self-through increases.

                                       MeTrIcS:-

·
   > Regardless or what is measured, how it is measured and whether it is for the sake of efficiency or effectiveness, there must be benchmarks - beseline values the system seek to attain.

   >Benchmarking is a process of continuously measuring system results, comparing those results to optimal system performance and identifying to improve system performance.

MeTrIcS:-


Efficiency IT metrics focus on technology and include :
  •      Throughput - the amount of information that can travel trough a system at any point.
  •      Transaction speed - the amount of time a system takes to perform a transaction.
  •      System availability - the number of hours a system is available for users.
  •      Information accuracy - the extent to which a system generates the correct results when executing the same transaction numerous times.
  •      Web traffic - includes a host of benchmarks such as the number of page views, the number of unique visitors, and the average time spent viewing a Web page.
  •      Response time - the time it takes to respond to user interactions such as a mouse click.


Effectiveness IT metrics focus on an organization’s goals, strategies, and objectives and include:
  •      Usability – The ease with which people perform transactions and/or find information. A popular usability metric on the Internet is degrees of freedom, which measures the numbers of clicks required to find desired information.
  •      Customer satisfaction – Measured by such benchmarks as satisfaction surveys, percentage of existing customers retained, and increases in revenue dollars per customer.
  •      Conversion rates – The number of customers an organization “touches” for the first time and persuades to purchase its products or services. This is a popular metric for evaluating the effectiveness of banner, pop-up, and pop-under ads on the Internet.
  •      Financial – Such as return on investment (the earning power of an organization’s assets), cost-benefit analysis (the comparison of projected revenues  and costs including development, maintenance, fixed, and variable), and break-even analysis (the point at which constant revenues equal ongoing costs).


  Security is an issue for any organization offering products or services over the Internet.
             It is inefficient for an organization to implement Internet security, since it slows down processing:
      However, to be effective it must implement Internet security.
      Secure Internet connections must offer encryption and Secure Sockets Layers (SSL denoted by the lock symbol in the lower corner of a browser) .

      
        Web Site Metrics:
  •      Abandoned registrations – Number of visitors who start the process of completing a registration page and then abandon the activity.
  •      Abandoned shopping carts – Number of visitors who create a shopping cart and start shopping and then abandon the activity before paying for the merchandise.
  •      Click-through – people who visit a site, click on an ad, and are taken to the site of the advertiser.
  •      Conversion rate – potential customers who visit a site and actually buy something.
  •      Cost-per-thousand (CPM) – sales dollar generated per dollar of advertising. This is commonly used to make the case for spending money to appear on a search engine.
  •      Page exposures – average number of page exposure to an individual visitor.
  •      Total hits – number of visits to a web site, many of which may be by the same visitor.
  •      Unique visitor – number of unique visitors to a site in a given time. This is commonly used by Nielsen/Net ratings to rank the most popular Web site.


                    SuPpLy ChAiN MaNaGeMeNt 

                                        MeTrIcS:-

  •  Back order - an unfilled customer order.
  • Customer order promised cycle time - the anticipated or agreed upon cycle time of a purchase order.
  • Customer order actual cycle time - to actually fill a customer’s purchase order.
  • Inventory replenishment cycle time - measure of the manufacturing cycle time plus  the time included to deploy the product to the appropriate distribution center.
  • Inventory turns ( inventory turnover ) - the number of times that a company’s inventory cycles or turns over per year.


                     CuStOmEr ReLaTiOnShIP

Marketing metrics.

BPR and ERP METRICS - The balanced scorecard enables organizations to measures and manage strategic initiatives.


CHAPTER 6: VALUING ORGANIZATIONAL INFORMATION.

OrGaNiZaTiONaL InFoRmATiOn:-

Ø  Information is everywhere in an organization.
Ø  Employees must be able to obtain and analyze the many different levels, formats and granularity of organizational information to make decisions.
Ø  Successfully collecting, compiling, sorting and analyzing information can provide tremendous insight into how an organization is performing.
Ø  Levels, formats and granularity of organizational information.  


·  Transaction information verses analytically information.



ThE VaLuE oF TiMeLy InFoRMaTiOn:-

ü  Timeliness is an aspect of information that depends on the situation.
ü  Real-time information – immediate, up-to-date information.
ü  Real-time system – provides real-time information in response to query requests.

ThE VaLuE oF QuALiTy InFoRMaTiOn:-

·         >Business decisions are only as good as the quality of the information used to make the decisions.
·        > You never want to find yourself using technology to help you make a bad decision faster.
·        > Characteristics of high-quality information include;
       
               Low quality information example;



UnDeRsTaNDiNg ThE CoStS oF PoOR InFoRMaTiOn:-

v  The four primary sources of low quality information include;

ü  Online customers intentionally enter inaccurate information to protect their privacy.
ü  Information from different systems have different entry standards and formats.
ü  Call center operators enter abbreviated or erroneous information by accident or to save time.
ü  Third party and external information contains inconsistencies, inaccuracies and errors.

v  Potential business effects resulting from low quality information include;

ü  Inability to accurately track customers.

                                     Increased Information Security

       vInformation is an organizational asset and must be protected

      vDatabases offer several security features including:
§Password – provides authentication of the user
§Access level – determines who has access to the different types of information

§Access control – determines types of user access, such as read-only access

vAlmost 90 million people had their personal information stolen or lost by organizations
§Bank of America: 1.2 million customers
§CardSystems: 40 million customers
§Citigroup: 3.9 million customers
§DSW Shoe Warehouse: 1.4 million customers.
§TJX Companies: 45.6 million customers
§Wachovia: 676,000 customers


   vA well-designed database should:

§Handle changes quickly and easily

§Provide users with different views

§Have only one physical view
\
Physical view – deals with the physical storage of information on a storage device
    Have multiple logical views

Logical view focuses on how users logically access information 

              Increased Scalability and Performance


vA database must scale to meet increased demand,  while maintaining acceptable performance levels

§Scalability – refers to how well a system can adapt to increased demands
§Performance – measures how quickly a system performs a certain process or transaction
     
Reduced Information      Redundancy
vDatabases reduce information redundancy


§Redundancy – the duplication of information or storing the same information in multiple places

vInconsistency is one of the primary problems with redundant information

Increase Information Integrity (Quality)

vInformation integrity – measures the quality of information

vIntegrity constraint – rules that help ensure the quality of information

§Relational integrity constraint
§Business-critical integrity constraint
