Consistency and Standards



In contrast, this is where YouTube performs worst. Two examples are:
i) Navigation history is lost when the user logs into the system, so, for instance, the loss of videos
watched, quick lists, etc; and

ii) Comments are frequently chats between users, but as these are not presented over a linear, dated
logic, the context and understanding are mislaid.

Error Prevention



This guideline is not observed; for example, when watching a video in a channel page, a table of contents is shown, although every time the user clicks in any of the other videos, the user is directed to a standard page losing any previous contextual information. In order to re-access it, being obliged to use the back button.

Concerning this guideline, YouTube performs generally well, as it keeps the user informed about what the system is doing, by providing information about loading and total video times.
 Match Between System and the Real World
This heuristic verifies to what extent the language of the interface respects the user s familiar language and concepts.



On the one hand the video controls, similar to domestic video players, respect real-world conventions,but on the other hand, there is a vast amount of unclear terminology and associated functions, such as: quicklists, featured videos or channel names.

User Control and Freedom

Copyright Infringement


Challenges
1. YouTube has a lot of issues with copyright infringement and
appropriateness of content.
2. Inappropriate content is an issue as school districts have started to block
access to the site to cut down cyber bullying.
3. Some governments prevent access to YouTube throughout entire nations
to limit access to some information and to protest content deemed as
offensive for moral or religious reasons.

Youtube’s core competency is video sharing. Prahalad and Hamel offer the following tests to identify the firm's core competencies:
  1. Is it a significant source of competitive differentiation?
I believe that there is a significant competitive differentiation between YouTube and its competitors such as Vimeo, Hulu, Youku, Tudou  etc. Google’s acquisition of YouTube for $1.65billion first helped to kill off most of their competitors. It broadened their popularity worldwide which meant that more people would continue to contribute and watch YouTube. According to market trackers at Hitwise, YouTube has a 45% share on the online video market which is more than its top four competitors combined.
Does it provide a unique signature to the organization?
YouTube is not unique with its technology but the experience and execution it provides a unique video sharing method that enables:
  • Usability
  • Community
  • Social network accessibility
Heuristic evaluation is a usability evaluation technique which allows experts to critique an interface by verifying its agreement with general and simple heuristics or principles, such as clarity, consistency or fluidity of navigation. YouTube’s usability was audited following the list of the ten Nielsen’s recommended heuristics for usable interface design.
General evaluation is shown by a positive, negative, present but unsatisfactory.
