Gantt Chart

A Gantt chart is a horizontal bar chart developed as a production control tool in 1917 by Henry L. Gantt, an American engineer and social scientist. Frequently used in project management, a Gantt chart provides a graphical illustration of a schedule that helps to plan, coordinate, and track specific tasks in a project.

A Gantt chart is a type of bar chart that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Terminal elements and summary elements comprise the work breakdown structure of the project. Some 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 "TODAY" line as shown here.

Although now regarded as a common charting technique, Gantt charts were considered revolutionary when they were introduced. In recognition of Henry Gantt's contributions, the Henry Laurence Gantt Medal is awarded for distinguished achievement in management and in community service. This chart is used also in Information Technology to represent data that has been collected.

Word Breakdown Structure

work breakdown structure (WBS) in project management and systems engineering, is a tool used to define and group a project's discrete work elements (or tasks) in a way that helps organize and define the total work scope of the project.

A work breakdown structure element may be a product, data, a service, or any combination. A WBS also provides the necessary framework for detailed cost estimating and control along with providing guidance for schedule development and control. Additionally the WBS is a dynamic tool and can be revised and updated as needed by the project manager.

The Work Breakdown Structure is a tree structure, which shows a subdivision of effort required to achieve an objective; for example a program, project, and contract. In a project or contract, the WBS is developed by starting with :

  • the end objective and
  • successively subdividing it into manageable components
  • in terms of size, duration, and responsibility (e.g., systems, subsystems, components, tasks, subtasks, and work packages)
  • which include all steps necessary to achieve the objective.


In the innovation management field the S-Curve illustrates the introduction, growth and maturation of innovations as well as the technological cycles that most industries experience. In the early stages large amounts of money, effort and other resources are expended on the new technology but small performance improvements are observed. Then, as the knowledge about the technology accumulates, progress becomes more rapid. As soon as major technical obstacles are overcome and the innovation reaches a certain adoption level an exponential growth will take place. During this phase relatively small increments of effort and resources will result in large performance gains. Finally, as the technology starts to approach its physical limit, further pushing the performance becomes increasingly difficult, as the figure below shows.


Critical Path Method, abbreviated CPM, or Critical Path Analysis, is a mathematically based algorithm for scheduling a set of project activities. It is an important tool for effective project management.

Originally, the critical path method considered only logical dependencies between terminal elements. Since then, it has been expanded to allow for the inclusion of resources related to each activity, through processes called activity-based resource assignments and resource leveling. A resource-leveled schedule may include delays due to resource bottlenecks (i.e., unavailability of a resource at the required time), and may cause a previously shorter path to become the longest or most "resource critical" path. A related concept is called the critical chain, which attempts to protect activity and project durations from unforeseen delays due to resource constraints.

Is Glutathione safe in the liver?

“ the levels of glutathione in the liver is critically linked to the liver’s ability to detoxify. The higher the
glutathione content, the greater the liver’s capacity to detoxify harmful chemicals. Typically, when we are
exposed to chemicals to which can damage the liver including alcohol, the concentration of glutathione
in the liver is substantially reduced. This reduction makes the liver susceptible to damage.

How to Make Glutathione Naturally Within the Body

There are several ways a body can manufacture glutathione. It is true it takes 3 amino acids for the body to manufacture glutathione but our bodies can take food, turn the foods into the substance to manufacture the 3 needed amino acids needed to manufacture glutathione. This is also the natural method for a body to create glutathione.

As an example, asparagus and watermelon will make glutathione.

With all of the breaking news regarding glutathione as an antioxidant as well as part of the reason for the development of autism, many supplements are suddenly jumping on the glutathione bandwagon.

Glutathione is not new to this Web Site. We have been recommending glutathione for the past 10 years to assist individuals to taper off psychotropic medications.

One thing that has been overlooked by many still is the role of glutathione within the liver as well as the role of glutathione transporting a toxin to the liver. There is considerable more to glutathione than having it in the cells.

The whey proteins mentioned on this site do make intracellular glutathione. However, like most other things in life, not all things are equal.

When you need intracellular glutathione quickly, the best method and safest method is with a whey protein. We have reviewed the top selling whey proteins. One whey protein stands so far above all others it is amazing.

Additional Glutathione Information

The non-essential amino acid homocysteine is produced in the body with the metabolism of the amino acid methionine.

Homocysteine is usually broken down into the amino acid cysteine. Cysteine is one of the amino acids needed by the cells to make intracellular glutathione. If your body does not convert homocysteine to cysteine the intracellular glutathione conversion will not take place.

The rapid conversion of homocysteine is critical. If conversion takes place too slow, homocysteine will accumulate in the body and damage cell membranes, damage blood vessels, increase the risk of cardiovascular disease, and atherosclerosis.

Rapid conversion of homocysteine requires an individual to have adequate amount of vitamin B6, B12, and folate. Over 50% of the population in the world has a genetic defect in the pathway needed to metabolize B6, B12, and folate.
