Group decision making in challenger launch

All these factors are considered prime to the formulation of "groupthink" [5]. Here is the first contributing factor. But I do not think you can blame the culture entirely.

The Shuttle was developed as a utility without a firm application. Smith, Pilot, Judith A. Unlike the Apollo mission, the Space Shuttle was approved as a method for operating in space, without a firm definition of what its operational goals would be [2] pg.

Therefore, a brief review of the contributing factors leading to the Challenger destruction is in order. The opinions in this analysis are those of the author and not necessarily those of the Editor or of DSSResources.

This was believed to be the result of supercooled air blowing on the joint from the liquid oxygen LOX tank vent. Aluminum oxides from the burned solid propellant sealed the damaged joint, temporarily replacing the O-ring seal before flame passed through the joint.

Once functional, the Shuttle became exposed to operational demands from a multitude of users. Each party began to rationalize that past success equaled future success [5]. Focus in this discussion will be placed on Thiokol - the subcontractor directly responsible for the development of the SRB "O" rings.

COM on Friday, October 7, They did not call for a halt to shuttle flights until the joints could be redesigned, but rather treated the problem as an acceptable flight risk. It will be difficult. It is one of the best investigations into the Challenger disaster out there and will be appreciated by those interested in that story from history.

The forecast for Florida did not show temperatures reaching this baseline for several days. Complacency began to grow among employees and safety considerations were traded for time spent on keeping the Shuttle on schedule and "the client of the day" satisfied.

Remembering the mistakes of Challenger written by Chris Bergin January 28, On this day, 21 years ago, the Space Shuttle Challenger and her crew of seven were lost when the vehicle broke up after 73 seconds of ascent, sending shockwaves through manned space flight that still remain today.

It is the opinion of this author that regarding the GDSS and decision to launch the ability of each member to have voted anonymously was the key factor that would have maintained the integrity of the GDSS and the quality of the decision.

Ice had accumulated all over the launch pad, raising concerns that ice could damage the shuttle upon lift-off.

Remembering the mistakes of Challenger

The events that followed for the crew are known to some of engineers close to the mission and need not be published — but ultimately the seven astronauts died when their cabin hit the ocean a few minutes later at over mph.

And how does one successfully navigate its use in a hardcore science context? It was later determined that these smoke puffs were caused by the opening and closing of the aft field joint of the right-hand SRB.

Group Support System - Critical Analysis There is little doubt that the environment from which NASA and its affiliated developers operated provided an opportunity for significant human error.

That broke the temporary seal created by the debris and a flame was seen breaching through the SRB joint. However, only selected senior officials were allowed to vote their "opinion", which they did verbally and at the request of NASA.

In Thick book that fascinates as we all think we know what happened the fateful day the Challenger exploded: Several engineers most notably Ebeling and Roger Boisjoly reiterated their concerns about the effect of low temperatures on the resilience of the rubber O-rings that sealed the joints of the SRBs, and recommended a launch postponement.

January Learn how and when to remove this template message Gray smoke escaping from the right side SRB The following account of the accident is derived from real time telemetry data and photographic analysis, as well as from transcripts of air-to-ground and mission control voice communications.

Secondly, it was not feasible to construct any complete management support systems MSS that could consider all of the factors associated with such a diverse group of environmental variables. A false sense of security was felt by NASA officials, with twenty-four successful Shuttle missions to their credit.

May their lives and subsequent tragic deaths remind us of the limitations of both people and technologies. Conceptually, the Space Shuttle was introduced during the crest of the successful Apollo mission.Lessons from the Challenger Launch Decision Additional Resources.

Sarah said: First, I have to commend Vaughan for a stunningly researched and wonderfully s /5. This article discusses the environmental and human decision making factors that were associated with the launching of the Space Shuttle Challenger on January 28, Shortly after launch, the Shuttle exploded destroying the vehicle and all crew members.
