Beta testing is the act of implementing a new idea, system, or product with a select group of people or processes in as controlled an environment as possible After beta testers identify potential problems and those problems are corrected, the idea, system, or product can be rolled out to the entire population of customers, employees, or processes The purpose of beta testing is to reduce the risks and costs inherent in launching an unproven product or system to a widespread audience  Someone with clout in the organization has a good idea or takes interest in someone  Based on past experience or knowledge, decision makers within an organization believe the idea will be successful The idea is implemented; sometimes it is implemented in beta mode so expenses and risks are minimized The success of the idea is weighed after implementation; problems are addressed after they impact products or processes in some way in the present or the future   Beta testing is sometimes used in a Six Sigma approach, but the idea or change in question goes through rigorous analysis and data testing first The disadvantage of launching ideas into beta or to an entire population without going through a Six Sigma methodology is that organizations can experience unintended consequences from changes, spend money through trial-and-error periods rife with opportunities for error In many cases, organi true gain or loss associated with the change Some improvements may appear to work on the surface without actually impacting customer satisfaction or profit in a positive way The Six Sigma method lets organizations identify problems, validate assumptions, brainstorm solutions, and plan for implementation to avoid unintended consequences By applying tools such as statistical analysis and process mapping to problems and solutions, SIX SIGMA IN MILITARY/DEFENSE officers by 40,000 employees, which was expected to be completed without any sacrifice to the Air Force's current level of operations - The Red River Army Depot Repair Facility in Texarkana, Texas has undergone a series of fruitful Six Sigma projects The facility has used Six Sigma to increase its ability to produce High Mobility Multipurpose Wheeled Vehicles (Humvees) by more than 7000 percent, going from three units a week to 32 in a day Furthermore, the cost of each vehicle has been cut in half, with an $89,000 cost of production turning into $48,000 per vehicle as a result of Six Sigma The main tools used to bring about these changes were the implementation of an assembly line process, improved time and personnel management and enhanced methods for keeping parts in stock Front-line staffers were particularly helpful in suggesting and implementing these changes In addition to the workflow modifications, the Red River Depot began placing stickers on the job site reminding workers that their work ultimately affects the lives of soldiers who fight to defend their country (http://www.dtic.mil/dtic/tr/fulltext/u2/a493547.pdf) - The Pine Bluff Arsenal, located in Arkansas, used Six Sigma to find a better way to produce and repair gas masks Thanks to their improvements, the rate of gas mask production has increased by 50 percent, while repair time has decreased by 90 percent - The Corpus Christi Army Depot saw Six Sigma drastically overhaul their previous process for helicopter repair Their Six Sigma project showed that the group was overhauling engines far too regularly As a result, the depot began overhauling engines after 900 hours of work, as opposed to the previous baseline of 309 In the end, the overhaul time was reduced by nearly 65 percent, while the reliability of the overhaul rose to more than 90 percent The trend of Six Sigma usage in the military is a positive development Although several projects have returned outstanding results, the industry is still merely scratching the surface of what Six Sigma can to help Future projects are sure to have major positive ramifications that will benefit all aspects of the military Because Six Sigma has become so popular in the military, units are encouraged to use any and all resources at their disposal when working on a project Although budgets are often 814 SIX SIGMA: A COMPLETE STEP-BY-STEP GUIDE subject to the whims of politicians, there are plenty of ways military personnel can improve their own processes, as well as the functions of others W overhaul everything at once Choosing the proper project scope will help military units to get the most out of their projects Projects should be big enough to make a huge difference, but not so big that management gets bogged down by the over-analysis of data and processes I onsider all possibilities when coming up with solutions Any process improvement, no matter how small, can provide tremendous benefit to the unit and, by extension, to the entire country Encouraging lower-level soldiers to speak up and identify their pain points will help the project team to come up with solutions that help everyone 815 At first glance, the government might not seem like the poster child for Six Sigma implementation The truly have to answer to its superiors or its constituents And yet, in many ways, the government is actually the perfect forum for Six Sigma process improvements T ly calls to mind elected officials that are responsible for helping the people in a given geographical area These individuals are tasked with many duties that are unseen by the average person Organizing local activities and appearing at community events barely scratch the surface of the responsibilities of an elected official Politicians must work with groups such as law enforcement and special interest organizations in order to facilitate changes that are demanded by the citizens of their local area Additionally, any progress made by the politician is subject to further review by other politicians, which results in many proposed changes never seeing the light of day The workflow of politicians would be less difficult if not for the non-stop stream of outside considerations that interfere with their duties Lobbyists and fellow politicians want support for their own causes, which prompts them to make pitches to other elected officials to garner support As a result, politicians are forced to devote time, energy and money to right thing to from a political perspective Elected officials must also work diligently to raise money, both for their own re-election campaigns and for the parties to which they belong Cold-calling in order to request donations is a harsh reality for many lower-level politicians, and fundraising dinners are the norm for higher-level officials These politicians are also required to acquire endorsements from important people in the community, including newspapers and unions With so much on promises for the future in order to gain support, as opposed to showcasing their track records from previous jobs While elected officials may be synonymous with the popular definition of government, there are plenty of other people that keep the industry running Everyday people that take jobs working in the government also have a say in how well the industry serves its people Civilians working in the government have a wide variety of responsibilities, including serving 816 SIX SIGMA: A COMPLETE STEP-BY-STEP GUIDE as court officials, DMV clerks, IRS auditors and countless other positions The politicians in initiatives The need for government employees to work with elected officials, and the potential for disagreements along the way, highlights the need for Six Sigma in government Additionally, Six Sigma may be able to help politicians to manage the many demands on their time Eliminate Red Tape While the government is commonly associated with being the ul T decision made by government members involves outside parties Citizens may be asked to vote on certain changes, while others simply require approval by higher authorities These added steps add significant lead time to the execution of approved items, often resulting in added costs and unhappy citizens (https://www.isixsigma.com/industries/governmentnon-profit/six-sigma-government-focusing-customer/) Incorporating Six Sigma can help any government office to increase its efficiency One of the main ways in which Six Sigma can make a notable difference is by identifying common areas where progress initiatives stall out It may turn out that a certain office is a culprit in delaying new actions, including improved processes that will help everyone Officials can then work with these offices to develop new ways of gaining approval that will speed up the implementation of new programs and processes Six Sigma can also highlight the true costs that come as a result of these delays For instance, a delay in the execution of an increase for automobile registration fees can ultimately cost a town or county millions of dollars Not only these delays present the image of a disorganized government, but they also hurt the citizens of that community Even if people feel as though they dodged a bullet by not having to pay the increased registration fee this year, they will ultimately have to pay additional money in other areas, The elimination of red tape allows the government to run more efficiently and transparently This makes it easier for the community to have more faith in its government, which ultimately will benefit all elected officials at re-election time 817 SIX SIGMA IN GOVERNMENT Improved Usage of Funding One of the most difficult aspects of government is getting things done with a limited C simply print money at will Financial prudence is important in government, just as it is in any business or industry A branch of government that incorporates Six Sigma will have a better idea of where their money is going, but the applications of Six Sigma go much deeper Thanks to the quality measures taken and the data collected over the course of the project, the government will have a better idea of how much of a return each investment provides A government group that spent $500,000 to renovate an ice skating rink may be pleased to find that residents have attended skating sessions at that rink twice as often over the past three years Discovering the financial potential of improving recreational facilities may inspire those officials to further enhance other government-owned properties, such as golf courses and batting cages This ability to track spending and return on investment may have tremendous benefits for politicians Instead of merely thanking donors for their contributions, elected officials can was positively impacted as a result of their generosity Such personalized shows of appreciation and consideration would be impossible without the data-driven philosophy of Six Sigma Time Allocation Government officials have a lot to In addition to dealing with the red tape that swallows many of their desired implementations, officials have to take time to meet with their constituents, maintain a presence in the community and attend important local events, such as graduations This is above and beyond the responsibilities typically associated with government, including passing laws, identifying avenues for process improvements and lobbying for the necessary support to get their initiatives pushed through the system These many activities take a great deal of time With so much that needs to get done, taking a step back to evaluate the typical workflow seems impossible Once again, Six Sigma comes to the rescue, prompting a re-evaluation of existing process and identifying ways to free up time without sacrificing productivity Just as with financial distribution, politicians will have the chance to see exactly how many hours each week they devote to the various aspects of their jobs Furthermore, as they did with funding, they will be able to see just how productive each of those hours turned out to be For example, a politician might find that fundraising for eight hours a week is marginally 818 SIX SIGMA: A COMPLETE STEP-BY-STEP GUIDE less effective than seeking donations for ten hours a week, proving that eight hours per week is the ideal amount of time to spend fundraising Those extra two hours can be reallocated to a function that needs more attention and that would generate a bigger return This approach to time management could be revolutionary for elected officials and any government employee that has too little time to carry out too many responsibilities A responsible distribution of time commitments may result in a more efficient government Checks and Balances The United States Constitution was written with an emphasis on checks and balances In other words, none of the three branches of government - judicial, executive and legislative should be able to obtain too much power In the event that one of those three branches becomes more prominent than the others, the remaining two branches have the wherewithal to use their power to check the growing branch On paper, this ensures that no one branch of the government can garner too much influence (http://www.usconstitution.net/consttop_cnb.html) T United States Republican officials are inclined to vote for Republican measures while voting down Democratic initiatives, and vice versa The selling point of staying within party lines is one of solidarity If a congressman is a Democrat and he or she wants to get a specific action passed, he or she will receive much more support if that congressman typically supports his or her party on a regular basis Note that these decisions often have little to with the actual preferences of the individuals in q T in and veto measures they actually like just to stay in good standing with their political parties Once again, the idea is that the entire party will stand behind a politician if he or she works with that party on their ideas However, the potential always remains for a “ “ ea 819 SIX SIGMA IN GOVERNMENT Limited Amount of Time Elected government officials come into office with the confidence of the people and their U Terms of service for elected officials ensure that there are a variety of voices contributing to solving the problems posed by the people of a given area They also make sure that no politician can rest on his or her laurels They need to generate results, and they need to so in enough time that voters can take note of the improvements before the next election Six Sigma can be helpful to government officials in so many ways However, the solutions “ “ -sensitive Gathering data, evaluating a broken process and devising ways to improve that process all take time, as I T I I up to each individual serving to make sure the future incorporates the updated processes and efficient workflow that have been implemented through Six Sigma Getting Buy-In The unfortunate reality of politics and government is that not everyone is willing to respect the wishes of other politicians Every politician has his or her idea of how things should be, and any elected official is eager to see those ideas implemented as soon as possible At the same time, politicians with a great vision for the future might see their ideas throttled by the people above them This can happen for a variety of reasons The aforementioned party line issue may change the minds of politicians; additionally, personal philosophies may take center stage, or senior politicians may simply want to take credit for the ideas of people that are lower on the food chain No matter what the situation may be, the fact is that not every good idea comes to fruition, cessary support This is unfortunate, yet unavoidable because of the Catch-22 involved Six Sigma requires total buy-in from all stakeholders who may benefit from a project, but most senior politicians the projected results of the initiative This results in improvements that are partially carried out - or not carried out at 820 SIX SIGMA: A COMPLETE STEP-BY-STEP GUIDE all - through no fault of the Six Sigma project team This can happen even if the team asked for permission before embarking on the project H T U “ W grown steadily over the years - Houston currently boasts more than million residents D H the city found itself facing a $140 million deficit in July 2015 (http://performance.houstontx.gov/sites/default/files/Industrial%20Engineer%20%20Case%20Study%20-%202015-02.pdf) “ “ H 2010s However, when the deficit grew to such a high number in 2015, it was time for Houston to get its most tenured employees involved Since many city employee had put in between 20 and 30 years on the job, this change was necessary in order for those employees to keep their jobs and keep contributing to the welfare of the city H “ “ A T O “ department was responsible for confirmation and payment associated with renting city equipment to other groups Unfortunately, the department suffered from rampant inefficiency It typically took Outside Services 111 days to resolve invoices received from vendors This was a far cr A demand answers The Six Sigma team implemented a series of process improvement measures that helped them to develop a revised process for handling the outside vendors These methods included process mapping, eliminating waste and developing a system for verifying that Outside Services was actually responsible for a given invoice The improved methods proved highly successful After beginning with an average cycle time of 111 days, Outside Services brought its average turnaround time down to 2.5 days Additionally, the group was able to reduce its staff from six employees to one However, this did not mean that those extra employees lost their jobs In fact, Houston has re-invested a variety of resources into its Six Sigma projects, including human capital 821 SIX SIGMA IN GOVERNMENT H Sigma green bel T “ “ W H “ The long-time employees of Houston not only get to continue serving the community, but they are able to so in new and exciting ways that have invigorated the entire staff of city employees The future is bright for Houston, as it is for any city that implements Six Sigma and continues to invest in its solutions Six Sigma is a great resource for both government employees and elected officials Since any improvement in government operations has a trickle-down effect that ultimately helps many people, even the smallest Six Sigma initiative can have large-scale benefits Inefficiency in the government hurts everyone - elected officials and government staffers all feel the strain of broken processes, and nobody faces the impact of these processes more than the citizens of these affected areas Bringing up any ideas that can help to improve the flow of government - ideas, money, time, etc - stands to benefit operations tremendously Government officials may be reluctant to undertake Six Sigma projects out of fear that they H way to use Six Sigma to its fullest potential Talking to everyone involved with a process from the most important people to the lowest-ranking officials - will help bring about a solution that benefits all parties involved Politicians must always remind themselves that the purpose of any Six Sigma project is to streamline internal operations in order to help the people that truly need assistance The focus should never deviate from that objective Re-elections and raising money must come a distant second to what really matters Source http://www.villanovau.com/resources/military/six-sigma-for-defense/ http://www.dtic.mil/dtic/tr/fulltext/u2/a493547.pdf
