【正文】 often arises when the work to be done requires the expertise that can only be performed by a small number of individuals. A system must be developed to ensure that people who are involved in the project are using their time efficiently. This is best acplished by developing a welldefined project schedule at the beginning of the project, with participation and input from each person who will be involved. There is always enough time to do what is required. Another plaint of some project managers is that people avoid accepting responsibility. People will avoid accepting responsibility if they fear unjust criticism if they make a mistake or feel they will receive inadequate recognition of their work. A manager must develop a project control system that protects a project from major mistakes that are catastrophic, yet tolerates minor mistakes that are people simply find it easier to ask the manager than to decide themselves because some managers want to make all the decisions. A project manager must clearly define the work required because people tend to achieve what is expected of them. ASSIGNMENT OF WORK Project management involves coordinating the work rather than doing the work。s web system. Another example is the application of project schedules, using an Intere nabled tool designed to allow team members to see their assignments across multiple projects using a web browser. Developing, maintaining, and municating the project schedule is vital to the process of project management. Whether through CPM（ Critical Path Method） scheduling or simple calendar schedules, a website can be used to post current and nearterm activities. In place of a local area work, a web server can be used as a central repository for project documents. The documents may include word processing files, spreadsheets, photographs, and drawings. Users can add and check in and check out existing documents. Documents and file systems can be used during the design or construction phase but are more mon in the design administration can also be greatly enhanced via the web. Webenabled systems can manage work flow. In addition to document management, the software can create, log, track, and index project documents. Other functions include todo lists, notification of events for project members, or required followup technology has made it extremely easy to take pictures and video and include them with documents on the websites. Complete photo histories can be stored in a database and be available for online retrieval. This can provide documentation during execution of the project as well as resolution of disputes. Job cost reports can also be published for review. For security, limited access to cost information can be provided without permitting access to an accounting reports can be published online with links to other information, such as schedules, cost reports, RFIs, or accident reports. This provides a way of giving users a documentbased database that is easy to maintain and control. Voice and multimedia are another application of project management via the Inter. The Inter can be used as a facilitator of voice munication. Email can now carry attachments video . Inexpensive hardware and software also allow two or more users to teleconference online or allow users to get a live video feed from an online is an effective tool for resolving problems in the field by a team of experts who may be located in the home office without requiring them to travel to the jobsite. Security of information can he addressed by use of Intras and Extras. An Intra is an Inter site set up for private use of a pany that might include certain corporate financial data, schedules, bulletins, and human resource information or other confidential information. Intras can save panies money by reducing the amount of hard copy notices and flies that might be printed and distributed manually or by mail. An Extra is an Inter site set up by a pany for shared use with others. It might contain a variety of information with limited or full access to its employees。 or the general public. Projectspecific websites are included in this category. The success of project management via the web has a tremendous potential for saving time and increasing productivity, but education and training are essential. The project manager must understand the technology and exercise innovation to adapt the new technology. For any new technology, precautions must be taken. For example, transmitting designs and data over the Inter can open up new areas for errors, omissions, and unauthorized revisions. Confirmed receipt of information may sometimes be necessary to ensure the information has been received. Use of the web is just one example of incorporating technology into the work process. As new technologies are developed the project manager must be responsive to potential applications and devise methods to incorporate the technology to increase the efficiency of project management. HUMAN ASPECTS The information is gathered and managed to successfully bring a project to pletion. Although a system must be developed for management and control of a project, it is people who make things happen. A project management system serves as a guide for overall coordination of the entire project。s happening, and in some instances those who don39。s organization) by owners or regulatory agencies, particularly in the review and approval process. Early in the project, the project manager must identify those activities that require external decisions so the appropriate information will be provided and the person can be identified who will be making the decisions. This must be included in the project schedule to alert the responsible parties so work is not disrupted and the project is not delayed due to lack of a de
