In setting up a fully functional web-site, a web developer must consider these three constructs: usability, visualization and functionality.

a)Usability
Usability refers to the elegance (style, smartness) and clarity (simplicity, clearness) with which the interaction with a web site is designed. Honestly, as a user i really like and comfortable with a website that very simple, well organized and has its own style. The style maybe can be the trademark for each website.The usability also considered pull-down menu, page turning navigation and index. Make sure all the navigation buttons do not make the users become more confused.The other thing that the developer must consider is scaffolding. Scaffolding is just like guider such as map, guide tour, table, search engine, land mark.Most importantly, the web site must be user friendly in order to make the user able to explore and navigate the web site easily.

b)Visualization
In the web site, visualization is the interface itself which is full of graphic, text and other media. Visualization do not bring any meaning if we do not describe what the visual is all about. Thus, as the developer, we must design a meaningful visual for our website.The visualization must definitely appeal to the users aesthetic as well as visual sensory. This is because, with an appropriate visualization, the contents as well as the items of a web-site will be easily understood.

c)Functionality
This refers to the function of the interface of the website.The web developer must ensure that the interface go alongside with the objectives and motives of the webpage.

A manager is a person who is seen to have the power, plans and leadership qualities in making sure that the management of a company,organization or institution runs smoothly in longer term.But can anyone hold the post as a manager?Yes perhaps with proper training, exposure and sufficient experience,a good manager could be born.But a manager also has to know his or her responsibility which includes three major elements:

A project manager must maintain the appropriate balance between these three elements.

A manager also has some options to make when it comes to the Management Models.They can choose The Traditional Organizational Hierarchy Model,Project Co-ordination Model or the Delicate Tension Model.

The Traditional Organizational Hierarchy Model.

• In this model, the manager has the full authority
• Decisions are taken at the top by the manager and then pass downwards to the other staffs.
• This may not make everyone happy as it denies the fact that expertise in specific areas lies near the bottom of the hierarchy.

The Project Co-ordination Model

• The manager will be at the centre of the hub,coordinating activities.
• The manager can easily loose control of the management process as desicions are made with no reference to the manager.

The Delicate Tension Model

• this is a more satisfactory model
• the manager is in possession of power and authority
• but the formal/infomal reporting and communication oo the other parties, without reference to the manager, as acceptable.

Whenever internet is concerned,we regularly end up surfing the net with different kind of feelings.To be exact,at times we may be totally satisfied with the speed of the delivery of the information needed and at some point, we may be taking hours to access certain web pages and later we end up logging off empty handed.So should all Web sites have the same speed limit so as not to disappoint the users?Scott Barber, an active member of the International Performance Testing community, in his article "HOW FAST DOES A WEBSITE NEED TO BE?" discussed further about this matter.

He concluded that there is no industry standard response times for Web sites.How fast is fast enough depends on many other factors which include who the customers are, what their needs are,where they are located,the connection speed used and etc.Mr Barber said that the performance expectation is influenced by user psychology, system consideration as well as usage consideration.

• user expectations - usually users will have higher expectations over a new sytem used, regardless of whether the previous system was a Web-based application,client/server or other configuration.


• resource limitations- includes time, money,people, hardware, networks and software
  
• stakeholders expectations - wants the best possible system for the least possible money.Their expectation are likely to change when decisions have to be made about tradeoffs.
