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。 trading partners, such as subcontractors。 and suppliers。 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。 however, some refinement and modification of the system is sometimes necessary for a particular project. People are the only resource that have the capability to detect problems and make the adjustments that are necessary to successfully manage a project. Thus, a project manager should not depend solely on the system of project management and neglect the importance of the people who are social with the project. To summarize, successful project management can best be described as effective munications between the people who perform the work that is necessary to plete the project. Management of any project requires coordination of the work of individuals who each provide an area of specialization. A successful project manager must be a good planner, dclegator, and municator. There is a tendency of some project managers to plain that the work is not being acplished because of factors beyond their control. For example, a project manager may feel that team members are too inexperienced, or that it takes more time to explain what needs to be done than the time it takes to do it themselves, or fear that a mistake by a team member would be too costly. Other typical examples are the feeling that others are too busy and don39。t have time for additional assignments or that others avoid accepting responsibility. Although these factors are of concern, they and similar factors are a routine part of working with people and can be overe with good management project managers have many years of experience of doing the work before their assignment of managing the work. Because they are familiar with what is required, they may prefer doing the work themselves rather than delegating it to others. The result is they bee overworked from attempting to both do and manage the work, spend nights and weekends devoted to their job, and then plain that the work is not acplished because others are too inexperienced. A project manager must realize that others can only gain experience by doing the work。 also that many times others can do the work just as well, if not better, than managers. The problem is acceptance of the fact that others may not do the work exactly the same way the manager would do it. The criterion should not be who can do the job best, but who can do the job satisfactorily. The project manager must balance accuracy and quality of the work for th
