LisaProject
LisaProject was the first GUI-based project management software. Developed for the Apple Lisa computer, LisaProject was conceived and implemented by Debra Willrett of SoloSoft and developed for Apple's Lisa computer. In 1981, Willrett realized that project management was a universal problem and that a GUI-based application would be a useful tool. She proposed what became LisaProject to Trip Hawkins at Apple. At the time, Apple was developing the Apple Lisa computer which had limited software. LisaProject was the first project management system to simplify the project management process by allowing the user to interactively draw their project on the computer in the form of a PERT chart. Constraints could be entered for each task, and the relationships between tasks would show which ones had to be completed before a task could begin. Given the task constraints and relationships, a " critical path", schedule and budget could be calculated dynamically using heuristic methods. On ...

Apple Lisa
Lisa is a desktop computer developed by Apple, released on January 19, 1983. It is one of the first personal computers to present a graphical user interface (GUI) in a machine aimed at individual business users. Its development began in 1978. It underwent many changes before shipping at with a five-megabyte hard drive. It was affected by its high price, insufficient software, unreliable Apple FileWare floppy disks, and the immediate release of the cheaper and faster Macintosh. Only 10,000 were sold in two years. Considered a commercial failure (albeit one with technical acclaim), Lisa introduced a number of advanced features that reappeared on the Macintosh and eventually IBM PC compatibles. Among them is an operating system with protected memory and a document-oriented workflow. The hardware was more advanced overall than the forthcoming Macintosh 128K; the Lisa included hard disk drive support, capacity for up to 2 megabytes (MB) of random-access memory (RAM), expansion slo ...

MacProject
MacProject was a project management and scheduling business application released along with the first Apple Macintosh systems in 1984. MacProject was one of the first major business tools for the Macintosh which enabled users to calculate the "critical path" to completion and estimate costs in money and time. If a project deadline was missed or if available resources changed, MacProject recalculated everything automatically. MacProject was written by Debra Willrett at Solosoft, and was published and distributed by Apple Computer to promote the original Macintosh personal computer. It was developed from an earlier application written by Debra Willrett for Apple's Lisa computer, LisaProject. This was the first graphical user interface (GUI) for project management. There were many other project management applications on the market at the time, but LisaProject was the first to simplify the process by allowing the user to interactively draw their project on the computer in the ...

Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...

Project Management Software
Project management software (PMS) has the capacity to help plan, organize, and manage resource tools and develop resource estimates. Depending on the sophistication of the software, it can manage estimation and planning, scheduling, cost control and budget management, resource allocation, collaboration software, communication, decision-making, quality management, time management and documentation or administration systems. Numerous PC and browser-based project management software and contract management software products and services are available. History Predecessors The first historically relevant year for the development of project management software is 1896, marked by the introduction of the Harmonogram. Polish economist Karol Adamiecki attempted to display task development in a floating chart, and laid the foundation for project management software as it is today. 1912 was the year when Henry Gantt replaced the Harmonogram with the more advanced Gantt chart, a scheduling d ...

Program Evaluation And Review Technique
The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project. First developed by the United States Navy in 1958, it is commonly used in conjunction with the critical path method (CPM) that was introduced in 1957. Overview PERT is a method of analyzing the tasks involved in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project. It incorporates uncertainty by making it possible to schedule a project while not knowing precisely the details and durations of all the activities. It is more of an event-oriented technique rather than start- and completion-oriented, and is used more in those projects where time is the major factor rather than cost. It is applied on very large-scale, one-time, complex, non-routine infrastructure and on Research and Developmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gantt Chart
A Gantt chart is a type of bar chart that illustrates a project schedule, named after its popularizer, Henry Gantt (1861–1919), who designed such a chart around the years 1910–1915. Modern Gantt charts also show the dependency relationships between activities and the current schedule status. Definition A Gantt chart is a type of bar chart that illustrates a project schedule. This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. The width of the horizontal bars in the graph shows the duration of each activity. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Terminal elements and summary elements constitute the work breakdown structure of the project. Modern Gantt charts also show the dependency (i.e., precedence network) relationships between activities. Gantt charts can be used to show current schedule status using percent-complete shadings and a vertical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Classic Mac OS-only Software Made By Apple Inc
A classic is an outstanding example of a particular style; something of lasting worth or with a timeless quality; of the first or highest quality, class, or rank – something that exemplifies its class. The word can be an adjective (a ''classic'' car) or a noun (a ''classic'' of English literature). It denotes a particular quality in art, architecture, literature, design, technology, or other cultural artifacts. In commerce, products are named 'classic' to denote a long-standing popular version or model, to distinguish it from a newer variety. ''Classic'' is used to describe many major, long-standing sporting events. Colloquially, an everyday occurrence (e.g. a joke or mishap) may be described in some dialects of English as 'an absolute classic'. "Classic" should not be confused with ''classical'', which refers specifically to certain cultural styles, especially in music and architecture: styles generally taking inspiration from the Classical tradition, hence classicism. ...
