UNIT 6: WEBSITE DEVELOPMENTUnit 6: Website DevelopmentLevel: 3Unit type: InternalGuided learning hours: 60Unit in briefLearners investigate website development principles. They will design and develop a website usingscripting languages.Unit introductionIncreasingly, organisations rely on websites to serve customers and, in some cases, to generaterevenue. With millions of web pages being created daily, the need for websites to be engaging,innovative and desirable is important. As a website developer, you must use sophisticatedtechniques to capture user interest and to ensure that customers are served. The scripting involvedin the development of websites has become crucial: website developers need to understand andacquire the necessary skills to find solutions to a variety of scenarios and problems.In this unit, you will review existing websites – commenting on their overall design andeffectiveness. You will use scripting languages such as Hypertext Markup Language (HTML),Cascading Style Sheets (CSS) and JavaScript and a simple text editor, or rapid applicationdevelopment tools. Finally, you will reflect on the website design and functionality using a testingand review process.Many software developers, database experts and systems managers need web-client developmentskills as an integral part of their overall portfolio of expertise. This unit will prepare you foremployment as a website developer or as a website development apprenticeship. The unitwill benefit you if you want to go on to higher education to develop your studies.Learning aimsIn this unit you will:A Understand the principles of website developmentB Design a website to meet client requirementsC Develop a website to meet client requirements.Pearson BTEC Level 3 National Extended Diploma in Information Technology –Specification – Version 1.0 final pre-publication – August 2016 Pearson Education Limited 201671

UNIT 6: WEBSITE DEVELOPMENTFurther information for teachers and assessorsResource requirementsFor this unit, learners must have access to software resources that will allow them to use tools andtechniques (given in the unit content) to design and develop websites. For example, text editors(such as Notepad ), rapid authoring software (such as Dreamweaver , KompoZer), File TransferProtocol (FTP) service (such as FileZilla ) to upload websites to a web server.Essential information for assessment decisionsLearning aim AFor distinction standard, learners will give a detailed and balanced evaluative report thatexplains how the two sites meet user requirements. This must be explored further by identifyingthe requirements of the websites, for example it has a secure login, and why these are importantfor the user. Learners will discuss what overall impact the site will have on the organisation,including positive and negative outcomes. The report will demonstrate high-quality written/oralcommunication through use of accurate and fluent technical vocabulary to support a well-structuredand considered response that clearly connects chains of reasoning.For merit standard, learners will show a clear understanding of how the two sites employdifferent principles of website design to develop websites that are creative and high performing.Learners will give a detailed analysis of how user needs and principles of website design impacton the design and development of a website. The report must provide a balanced discussion,supported by reasoned examples. It will be technically accurate and demonstrate good-qualitywritten/oral communication.For pass standard, learners will give a detailed comparison of two websites, for example Asdaand Tesco – two similar commerce sites, with an explanation of who the site is aimed at andits purpose. Learners will explain the use of design principles in each website to compare theirapplication. The evidence may have some inaccuracies and the comparison may be unbalanced.Learning aims B and CFor distinction standard, learners will draw on and show synthesis of knowledge across thelearning aims to evaluate how the decisions and methodologies applied throughout the design,development, maintenance, optimisation and testing stages of their website impacted on the overalloutcomes. They will consider whether the website meets client requirements, including achieving itsstated purpose and appealing to the target audience. Learners will justify their designs and providea discussion on why alternative designs were not used.Learners will give a detailed and balanced evaluation of how effectively their completed websitemeets the client requirements, including appealing to the target audience and meeting its statedpurpose, in comparison to alternative solutions. Their evaluation will be supported by evidencefrom all stages of the project to reach conclusions and suggest developments. The evaluationmust contain a systematic and accurate review of their own skills, performance and behavioursand the impact that this had on the development of the final website. Learners will take individualresponsibility for their own work, for example identifying potential issues and resolving them,reviewing their work and making improvements, keeping their work safe and secure, and showingresponsible use of quoted materials. Creativity will be shown, for example, by taking innovativeapproaches to problem solving and through the originality of their solution.78Pearson BTEC Level 3 National Extended Diploma in Information Technology –Specification – Version 1.0 final pre-publication – August 2016 Pearson Education Limited 2016

UNIT 6: WEBSITE DEVELOPMENTFor merit standard, learners will apply their knowledge through selection and application ofappropriate methodologies to design, develop, maintain and test an effective, optimised websiteto meet client requirements. Learners will produce comprehensive designs, including alternativesolutions. When developing their website, learners will produce an optimal solution to meet clientrequirements as closely as possible. Learners will also gather and analyse feedback on their websitein order to make improvements. Learners will record the changes that are made and producesubsequent versions of the website as appropriate.Learners will give a clear analysis of the success of their solution, giving accurate and reasonedsuggestions as to how the solution could be improved, they will discuss alternative solutions thatcould be implemented if the task were to be repeated. They will consider how decisions they madeduring the project affected the outcomes and justify why these decisions were made. They will givean evaluation of how their skills and behaviours affected the outcomes of the website.For pass standard, learners will apply understanding through the planning and development ofthe website to meet client requirements. Learners will produce detailed designs for their website,including user requirements, visual designs and technical documentation. Learners will carry outand document a number of tests and reviews of the website (including use of test users andappropriate test plans, schedules and test data) to ensure that the solution works and meets theidentified criteria. They will give evidence that different types of testing have been carried out andthat important problems and errors identified have been responded to. Learners’ websites will befunctional and meet the identified requirements but there may be some performance issues and/orthe implemented solution may not be as efficient or effective as it could be.Learners will review how the decisions they made during planning and development affected thewebsite. Learners will explain the extent to which the website meets the initial project brief. Theywill consider both positive and negative aspects of the website, although their review may beunbalanced and/or superficial. They will make reference to the possible alternative solutions thatcould be implemented.Links to other unitsThis unit links to:xxxxxxxxxxxUnit 1: Information Technology SystemsUnit 3: Using Social Media in BusinessUnit 4: ProgrammingUnit 7: Mobile Apps DevelopmentUnit 11: Cyber Security and Incident ManagementUnit 12: IT Technical Support and ManagementUnit 14: IT Service DeliveryUnit 15: Customising and Integrating ApplicationsUnit 16: Cloud Storage and Collaboration ToolsUnit 17: Digital 2D and 3D GraphicsUnit 18: Digital Animation and Effects.Employer involvementThis unit would benefit from employer involvement in the form of:x guest speakersx technical workshops involving staff from local organisations/businessesx contribution of design/ideas to unit assignment/scenario/case study/project materials,including own organisation/business materials as exemplars where appropriatex feedback from staff from local organisations/businesses on plans/designs/items developedx opportunities for observation of organisational/business application during work experiencex support from local organisation/business staff as mentors.Pearson BTEC Level 3 National Extended Diploma in Information Technology –Specification – Version 1.0 final pre-publication – August 2016 Pearson Education Limited 201679
