The Gantt Chart: Already Dead Or Still Alive?


The theory that something is Regarded as dead automatically suggests that it was living before. As we aren’t speaking about a individual here but about a visualization technique, living and dead in different words imply that this technique had a worth previously but is considered no more needed today. Consequently, it could be worth it to lock back in the past when a Gantt chart not only was viewed as precious, but also as groundbreaking instrument. This may reveal a few more insights it may have expired since then.

The surroundings, for which Henry Laurence Gantt devised his Graphs, was that the manufacturing business and the prime usage case was that the progress of managerial decision-making from the scheduling procedure. The plan of this Gantt graph followed the question that data a foreman or manager required to determine as a way to rapidly understand if or not a manufacturing was on schedule, beforehand or running late. Gantt introduced the concept to utilize time and resource use and no more amounts for a yardstick for making scheduling decisions, and generated various kinds of graphs based upon the individual demands of their manufacturing supervisors. These executives in the time needed to handle bottlenecks, were assumed to manage uncertainty, and had to deal with problems caused by the high amount of human participation to industrial manufacturing. With this particular environment, Henry Gantt produced a chart that outlined all appropriate data at one glance to allow supervisors making deep scheduling choices.

In Brief, the Gantt graph was living when the Following attributes were fulfilled: It needed to be manufacturing environment where decision support for monitoring procedures were required and required context-sensitive data (“for human demands”) at a single glance taking into consideration resource and time use as essential determinants.

What’s changed since then to announce the Gantt chart deceased?

Although we are going towards the so-called service Society, the accumulative net output of the production sector still counts for over 25 percent of the global GDP (source: World Bank). Undoubtedly, this business still has its own relevance. Competition is growing and several products increasingly turned into a commodity. Both tendencies induce a gross pressure particularly in the manufacturing market. This permits making the first assumption that scheduling procedures are now even more significant, and as such the resources providing decision support for scheduling jobs.

This premise could be reinforced by three center evidences: First, It appears to be common belief that time is an integral success factor for manufacturing businesses. An underlining proof for this frequent sense can originated from appearing at frequent key performance indicators like time-to-market or manufacturing modalities such as just-in-time. This raises the question why a time-focused monitoring tool is seen as obsolete. Secondly, because the fantastic old times of Henry Gantt the ratio repair prices to variable costs has been getting increasingly more mend cost-savvy. That can be and even accurate for manufacturing environments. In fix cost-intensive locations, people typically must set a high emphasis on the finest possible source use to make maximum utilization of their correct cost-driving capacities. Again, the query has to be raised a resource-focused visualization to support scheduling choices ought to be obsolete in a situation like this. Third, one should consider decision support . The shipping of context-sensitive data has emerged as a single candidate for getting a new paradigm to the design of decision support methods. This becomes much more significance if a person chooses the enormous data growth into consideration. Henry Gantt meant to make exactly this. His graphs were supposed as a context-sensitive instrument to boost time- and – resource-based scheduling choices. For the next time the query has to be raised why this can be regarded as obsolete. The reverse appears to be accurate: For manufacturing firms, there’s more demand to get a Gantt chart than previously.

Ultimately and honest enough: Lots of them “the Gantt is Dead” urges come in the project management market. This particular use case of a Gantt chart hasn’t yet been analyzed here. The focus here is to demonstrate that the Gantt chart as Henry Gantt devised its alive and should be living in the manufacturing market. I believe, this question was definitely answered.
