PERT originated in 1958 with the ... Polaris missile design and construction scheduling. Since that time, it has been used extensively not only by the aerospace industry but also in many situations where management desires to achieve an objective or complete a task within a scheduled time and cost expenditure; it came into popularity when the algorithm for calculating a maximum value path was conceived. PERT and CPM may be calculated manually or with a computer, but usually they require major computer support for detailed projects. A number of colleges and universities now offer instructional courses in both.[1]

Problems arise in every organization. Such problems as what products/systems to develop, should capacity be expanded, or should a computer be purchased are just a few of an endless number of continuing problems about which management must concern itself if the firm is to survive. These problems and their alternative solutions establish some elements of change around which the organization must adapt. Projects are generally established to carry out these changes and someone is always responsible for each project's successful completion.[11]

Every project is unique in terms of the problems that arise, the priorities and resources assigned it, the environment in which it operates, and the project manager's attitude and style used to guide and control project activities. Therefore, the organizational structure for the project must be designed to fit within that project's operating constraints. The organizational structure implemented may not be the same structure used throughout the life cycle of the project due to changes in priorities, available resource, project personnel, laws, and other contingencies. Regardless of the project management structure chosen, management must realize that a dynamic state of equilibrium between limited personnel and financial resources and the objectives of the project will be necessary if project management is to be successful in their particular organization.[11] Before touching on the major tools and techniques of project management, let's get to the bottom of what project management truly is. Later, I will list the benefits that the tools and techniques of project management bring to the systems analysis process.

Project management tools have evolved from simple spreadsheet products to sophisticated, Web-based project information portals. The obvious trend in project management software, as with almost everything in information technology, is a move toward Web-based systems. Most project management tools can be accessed via browsers and those that do not currently have this capability are moving in that direction.[17] One product that allows users to take non-Web-based project management tools and to then bring the data to a Web browser is mesaVista from Mesa Systems Guild, Warwick, R.I. The product acts as a portal development tool that allows firms to view information from products such as Microsoft Project over the Web. These project management portals are becoming more common as the collaboration capabilities of project management tools improve.[9]

Project management tools continue to evolve in terms of capabilities and user interface. The general direction is toward more integrated process and knowledge management systems, and user interfaces with a "Web" look.[17] Project management tools are gradually becoming integrated project information portals with capabilities far beyond simple project tracking and reporting.[9]

Project management can be understood as a systematic way of planning, scheduling, executing, monitoring, controlling the different aspects of the project, so as to attain the goal made at the time of project formulation. PERT and CPM are the two network-based project management techniques, which exhibit the flow and sequence of the activities and events. Program (Project) Management and Review Technique (PERT) is appropriate for the projects where the time needed to complete different activities are not known.

Gantt charts are created using project management information system (PMIS) applications, such as Primavera Project Planner®, Microsoft Project®, and MindView®. A typical approach for creating a schedule is to hold meetings with selected project team members and to begin identifying activities. While this approach will result in a schedule, it may not be a complete schedule. A complete schedule contains enough activities to ensure compliance with the 100% Rule. The 100% Rule requires that the scope baseline addresses 100% of the project scope. The scope baseline components are the primary sources used to identify the schedule activities. If the scope baseline addresses 100% of the project scope, then the schedule activities address 100% of the project scope. Following these steps will ensure that the final project schedule is a complete schedule.

The Agency, in collaboration with the experts of the Sector organizations, has carried out the analysis and assessment of the CR in the database that can be considered as errors in the system specifications, with a view to identify those errors which could prevent the system to provide normal service according to Article 10 of the Commission Regulation (EU) No 2016/919. This opinion supersedes and replaces the opinion ERA/OPI/2017-2. 2b1af7f3a8
