Conception

Scrapbook design through meetings and

examples

current branding and marketing material areused to formulate a group of ideas that

articulate the company's objectives.

 Anchor points discussed and created

These areas form critical points of reference for 

the whole design process and are considered the

premier traffic pages.

Performance, Load & Stress

Testing

Load testing is the practice of modeling the

expected usage of a software program by simulating

multiple users accessing the program's services

concurrently. Performance testing is performed, from one

perspective, to determine how fast some aspect of a

system performs under a particular workload.

Stress testing is a test that put a greater emphasison robustness, availability, and error handling under 

a heavy load, than on what would be considered

correct behavior under normal circumstances.

Web Accessibility

refers to the practice of making websites

usable by people of all abilities and

disabilities.

Web Accessibility

Visual: Visual impairments including blindness, various commontypes of low vision and poor eyesight, various types of colour blindness;

Motor/Mobility: e.g. difficulty or inability to use the hands,including tremors, muscle slowness, loss of fine muscle control,

etc., due to conditions such as Parkinson's Disease, muscular dystrophy, cerebral palsy, stroke;

Auditory: Deafness or hearing impairments, including individualswho are hard of hearing;

Seizures: Photoepileptic seizures caused by visual strobe or flashing effects.

Cognitive/Intellectual: Developmental disabilities, learningdisabilities (dyslexia, dyscalculia, etc.), and cognitive disabilities of various origins, affecting memory, attention, developmental"maturity," problem-solving and logic skills, etc.

Usability Testing

means for measuring how well people canuse some human-made object (such as aweb page, a computer interface, a document,

or a device) for its intended purpose, i.e.usability testing measures the usability of theobject.

Usability testing focuses on a particular 

object or a small set of objects, whereasgeneral human-computer interaction studiesattempt to formulate universal principles.

Implementation

website is uploaded to the agreed location

Monitoring

what happens after the delivery of a website

is equally as important to all that takes place

beforehand.

website designs incorporate a query logging

facility that can be used by clients to log

queries direct to designers and developers.
