Generally speaking ICTarchitecture relates to hardware, software, access and protocols and the overall design of an ITsystem including logical and physical interrelationships between its components.Areas of IT architecture can include practices such as: Technology Enterprise IT governance Information architecture Data Solutions Applications Systems Business Risk management and securityICT architecture can be seen as a series of principles and guidelines used to direct the process ofpurchasing, developing, modifying and interfacing IT resources throughout an organisation.Resources can include hardware equipment, software, communications, methodologies, modellingtools and organisational structures, standards and procedures.Obtaining the client’s business specifications and business requirementsThe business needs of an organisation should be aligned with the ICT strategy. ICT strategic planningaligns technology with business goals, which should support the organisation’s strategic objectives.When planning the ICT needs of an organisation, the overall strategic direction of the organisationneeds to be understood so that it can work towards those objectives. An ICT strategic plan outlineshow technologies would be used within an organisation to assist it in achieving its objectives.Class activity: refer to the following ICT strategic plan which provides an example of an ICT strategy:https://www.homeaffairs.gov.au/about/access-accountability/plans-policiescharters/plans/information-and-communication-technology-ict-strategyProducing an ICT network architecture design for a client can refer to an external organisation, withinan enterprise (for example a department, franchise, branch or business area), or a service industry,government body or ICT company.© MILCOM Communications Pty Ltd trading as MILCOM Institute | RTO No. 6859 | CRICOS Provider Code:03491GHead Office: Unit 12/1866 Princes Highway Clayton VIC 3168 | Phone: 1300 369 320 | Email :[email protected]Student Guide for ICTTEN611 | v 1.0 | Last reviewed: May 2019 | Not controlled when printed Page 10 of 26The type of business specifications that a client may have can include: A budget allocation for ICT Cost estimates for a project Their current system and functionality Identified future expansion and growth forecasts Specific technical requirements and needs Timelines for design, development and deployment. A user problem statement.
