Web Development Process

Where do websites come from…?

Web Development Process

• All websites start with an idea!• Wouldn’t it be great if people could find

information about my company online…?• Wouldn’t it be great if people could buy our

products online…?• Wouldn’t it be great to make a site so interes-

ting that millions would visit it each day, and then earn millions on ads…?

Web Development Process

• Wouldn’t it be great if people could buy our products online…?

Now you know enough, start working!!

…and the deadline is in three weeks, btw!

Web Development Process

• Clearly, the idea itself is not enough• From idea follows purpose (mission)• Often close to the idea, but somewhat more

specific• The website should enable people to buy a

broad selection of our products online, at the same prices as in our physical stores

new products, …)– How are updates handled (CMS, Service,…)?

• Subjective!!!

Web Development Process

• Try to define objective goals instead!

Web Development Process

• ”Easy”• It must be possible for 80 % of the users to

complete an online purchase within 90 seconds, when starting from the landing page of our website

Web Development Process

• ”Broad selection”• At least 90 % of all the items in the company

product catalog must be available for purchase online

Web Development Process

• ”Positive user experience”• At least 80 % of the users participating in a

user survey must give the item ”overall user experience” a rating of 7 or more on a scale from 0 to 10. At most 5 % must give the item a rating of 3 or less.

something determines what the message is”• Who are we talking to…?

Defining a Target Audience

Web Development Process

• Purpose and target audience will often – but not always – be rather closely related

• Ideally, everybody should like our website!• In practice, only certain specific groups will be

appealed to by our product, message, form of expression, etc.

• Who are they…?

Web Development Process

• How can you characterise a certain Target Audience?– Geography– Demography– Psychography– Level of competence

Web Development Process

• Geography– Local/regional/national/

international– Urban/suburban/rural– Climate– Workplace/home

Web Development Process

• Demography– Age– Gender– Civil status (single, married,…)– Occupation– Education– Income level– Ethniticity– …

Web Development Process

• Psychography– Interests– Behaviour– Beliefs– Values– Culture/Subculture

Web Development Process

• Level of competence (with regards to Web usage)– Novice– Casual– Intermediate– Expert

Web Development Process

• Why is this relevant – what can the practical consequences be?

• Imagine these target audiences:– Children age 5-8– Senior citizens, age 60+– Adults (age 18-60), elementary education

• What is the influence on our design decisions?
