  • groupwareSoftware that integrates work on a single project by several concurrent users at separated workstations.workflowThe automatic routing of documents to the users responsible for working on them. Workflow is concerned with providing the information required to support each step of the business cycle. The documents may be physically moved over the network or maintained in a single database with the appropriate users given access to the data at the required times. Triggers can be implemented in the system to alert managers when operations are overdue.Workflow Keeps Documents MovingThe manual flow of documents in an organization is prone to errors. Documents can get lost or be constantly shuffled to the bottom of the in-basket. Automating workflow sets timers that ensure that documents move along at a prescribed pace and that the appropriate person processes them in the correct order.Workflow IntegrationIntegrating workflow into existing software applications may require extensive reprogramming, because although independent workflow software can launch a whole application, a workflow system must be able to invoke individual routines within the application. As a result, vendors of application software have teamed up with workflow vendors to provide the appropriate interfaces and/or they have developed their own workflow capability. Workflow standards developed by the Workflow Management Coalition www.wfmc.org) provide interoperability between workflow software and applications as well as between different workflow systems (see Wf-XML).Workflow Vs. WorkgroupWorkflow software is not the same as workgroup software, otherwise known as groupware. Workflow deals with the step-by-step processes, whereas workgroup systems are concerned with information sharing and threaded discussions among users.

Simple Object Access Protocol) A message-based protocol based on XML for accessing services on the Web. Initiated by Microsoft, IBM and others, it employs XML syntax to send text commands across the Internet using HTTP.Web Services Description Language) An XML-based language for defining Web services. Developed by Microsoft and IBM, WSDL describes the protocols and formats used by the service.Universal Description, Discovery and Integration) An industry initiative for a universal business registry (catalog) of Web services turned over to the stewardship of OASIS in 2002 as the version 3 specification of UDDI was released. Service Oriented Architecture) The modularization of business functions for greater flexibility and reusability. Instead of building monolithic applications for each department, an SOA organizes business software in a granular fashion so that common functions can be used interchangeably by different departments internally and by external business partners as well.

  • Types of Computers
    Computers come in different sizes with varying capabilities for processing information
    Measured in FLOPS (FLoating point OPerations per Second)…how fast it process commands per second.
    Personal computer (PC) 32-64 instructing per seconds (dual processors can handle more than that)
    Workstation: about 100X faster….but with specific purpose. May be PMS. Statler doesn’t have PCs anymore: it’s a keyboard, a screen and all units point to one place
    Midrange computers: Servers and minicomputers: Multiple access use. Most servers are these
    Mainframe: in corporations.
    Supercomputer: IBM. “A larger Mainframe” Mainframes working in unison

    IT Infrastructure: Computer Hardware
  • The Need For Speed!
    The dominant chip architecture is multicore processors. Dual-core processors are also widely found in the TOP500 (the top 500 big computers).
    IBM and HP have sold the majority of the systems in the TOP500 (over 50% in the USA).
    The IBM BlueGene/L system claimed the Number 1 spot, which had been in first place since November 2004.
    Intel processors were used in a whopping 70% of the 2007 systems. AMD Opterons came in second place, while IBM POWER chips were third.
    Speed doubled! The 2007 winner achieved a Linpack benchmark performance of 478.2 teraFLOPS (TFLOPS), as compared to 280 TFLOPS just six months earlier, before a major upgrade. Top speed now is 596 TFLOPS
    In 2008, the Cell/AMD Opteron-based IBM Roadrunner at the Los Alamos National Laboratory (LANL) was announced as the fastest operational supercomputer, with a sustained processing rate of 1.026 PFLOPS. It uses 2 different architectures (hybrid system).

    Important issues faced by IT Managers
  • Business Continuity Planning (BCP)
    BCP is an approved set of preparations and sufficient procedures for responding to a range of disaster events, such as:
    Planning stage – alternative business recovery operating strategies are determined
    Emergency Response Procedures – designed to prevent/limit injury to personnel on site, damage to structures/equipment and the degradation if vital business functions
    Employee Awareness and Training Programs – must be well communicated throughout the organization
    49

  • Manager’s Role :Strategy to IS Implementation
    Business Strategy drives architecture.
    Managers must understand how to plan IT to realize business goals.
    Logical framework is used to guide the translation from business strategy to IS design.
    Know the state of existing architecture and infrastructure when translating strategy into architecture and then infrastructure.
    A business continuity plan is an approved set of preparations and sufficient procedures for responding to a disaster event.
    It is becoming more important that business managers effectively translate business strategy into IT infrastructure.
