Learning aim A: Understand the principles of website development
A1 Purpose and principles of website products
The concepts and principles of website production.
•
Purpose of websites, including the features of:
o
content-based (Web 2.0 technologies)
o
product and/or service-based
o
target audience, e.g. social networker, seekers, gamers, buyers, age profile, gender
o
requirements, e.g. user-friendly, consistent, navigational, customisable, flexible.
•
Principles of website design, e.g. usability, white space, site layout, accessibility,
spacing, navigation, typography, alignment, clarity, consistency/intuitiveness,
accuracy, content, media, simplicity.
•
Media and objects, e.g. position, colour, contrast, size, appropriateness.
•
Creativity and innovation, e.g. unconventional layouts, white space, ‘outside of
the box’ thinking, golden ratio.
•
Search engine optimisation, e.g. indexing (meta tags), use of keywords,
importance of updates, limiting crawling.
A2 Factors affecting website performance
Requirements of website performance to support organisational requirements.
•
Where scripts run (on the web server – server-side scripts, or the local client
machine – client-side scripts).
•
Browser compliance, e.g. which elements are supported by different browsers.
•
Server-side factors, e.g. bandwidth availability, number of hits, file types.
•
Client-side factors, e.g. upload and download speeds, browser, cache memory,
processor speed, interactivity.
Learning aim B: Design a website to meet client requirements
B1 Website design
Website design requirements driven by the priorities of an organisation.
Understanding the steps involved in developing a design for a client website.
•
Problem definition statement requirements: intended audience, full summary
of the problem to be solved, constraints, benefits, nature of interactivity,
complexity of the website.
•
Purpose requirements as defined in a client brief for their interactive website.
•
Application of website design principles by professionally created websites.
•
Initial design ideas/prototypes (illustrating design principles) and the
requirements for an interactive website, including:
o
diagrammatic illustrations, e.g. storyboard, mood board, wireframe,
site maps
o
realistic representations
o
search engine optimisation
o
alternative design ideas/prototypes, including compatibility with
mobile/tablet devices.

•
Client-side scripting design tools and techniques, e.g. pseudocode, flow charts
(including use of British Computer Society (BCS) standard flow chart symbols)
used to develop original code.
•
Effective use of ready-made and/or original assets, e.g. a digital animation,
digital graphic, digital audio and video, or any other combined assets.
•
Obtaining and using feedback from others to help refine alternative design
ideas/prototypes and make decisions.
•
Testing plan requirements and its completion with test data,
to test functionality.
•
Identifying technical and design constraints and working around them.
•
Local legal and ethical considerations applicable.
