Six Sigma

Six Sigma has received much attention worldwide as a management strategy that is said to have brought about huge improvements and financial gains for such big-name companies as Allied Signal, General Electric (GE) and Motorola.

If you want to give your business the chance to attain the same resounding success, Six Sigma could be the method that will steer you towards that direction.

What is Six Sigma?

So what really is it? Six Sigma is a business management tool that was developed using the most effective quality improvement techniques from the last six decades. Basing its approach on discipline, verifiable data, and statistical calculations, Six Sigma aims to identify the causes of defects and eliminate them, thereby resulting in near-perfect products that meet or exceed customer’s satisfaction.

The core concept behind the Six Sigma method is that if an organisation can quantify the number of “defects” there are in a particular process, improvement activities can be implemented to eliminate them, and get as close to a “zero defects” scenario as possible. Defect here is defined as any process output that fails to meet customer specifications.

Six Sigma is also unique from other programs in that it calls for the creation of a special infrastructure of people within the organisation (“Champions“, “Black Belts“, “Green Belts“) who are to be expert in the methods.

Six Sigma Methodologies

When implementing Six Sigma projects, two methodologies are often employed. Although each method uses five phases each, these two are distinguished from each other using 5-letter acronyms and their specific uses.

DMAIC ? is the project methodology used to improve processes and maximise productivity of current business practices. The 5 letters stand for:

  • D ? Define (the problem)
  • M ? Measure (the main factors of the existing process)
  • A ??Analyse?(the information gathered to deter mine the causes of defects)
  • I ? Improve (the current process based on the analysis)
  • C ? Control (all succeeding processes so as to minimise additional defects)

DMADV – is the method most suitable if your business is looking to create new products or designs. The acronym stands for:

  • D ? Define (product goals as the consumer market demands)
  • M ? Measure (and identify product capabilities and risks)
  • A ??Analyse?(to create the best possible design)
  • D ? Design (the product or process details)
  • V ? Verify (the design)

How does Six Sigma differ from other quality programs?

If you think that Six Sigma is just another one of those business strategies that produce more hype than actual results, think again. Six Sigma uses three key concepts that sets it apart from other business management methods.

  • It is strictly a data-driven approach, where assumptions and guesswork do not figure in the decision making.
  • It focuses on achieving quantifiable financial results ? the bottom line ($) ? as much as giving emphasis on customer satisfaction.
  • It requires strong management leadership, while at the same time creating a role for every individual in the organisation.

Is Six Sigma right for your business?

While many other organisations such as Sony, Nokia, American Express, Xerox, Boeing, Kodak, Sun Micro-systems and many other blue chip companies have followed suit in adopting Six Sigma, the truth is, any company — whether you have a large manufacturing corporation, or a small business specialising in customer service.

Certainly, there is a lot more to Six Sigma than what you can probably absorb in one sitting or reading.

FUJIFILM Cracks the Energy Code

FUJIFILM was in trouble at its Dayton, Tennessee plant in 2008 where it produced a variety of speciality chemicals for industrial use. Compressed-air breakdowns were having knock-on effects. The company decided it was time to measure what was happening and solve the problem. It hoped to improve reliability, cut down maintenance, and eliminate relying on nitrogen for back-up (unless the materials were flammable).

The company tentatively identified three root causes. These were (a) insufficient system knowledge within maintenance, (b) weak spare part supply chain, and (c) generic imbalances including overstated demand and underutilised supply. The maintenance manager asked the U.S. Department of Energy to assist with a comprehensive audit of the compressed air system.

The team began on the demand side by attaching flow meters to each of several compressors for five days. They noticed that – while the equipment was set to deliver 120 psi actual delivery was 75% of this or less. They found that demand was cyclical depending on the production phase. Most importantly, they determined that only one compressor would be necessary once they eliminated the leaks in the system and upgraded short-term storage capacity.

The project team formulated a three-stage plan. Their first step would be to increase storage capacity to accommodate peak demand; the second would be to fix the leaks, and the third to source a larger compressor and associated gear from a sister plant the parent company was phasing out. Viewed overall, this provided four specific goals.

  • Improve reliability with greater redundancy
  • Bring down system maintenance costs
  • Cut down plant energy consumption
  • Eliminate nitrogen as a fall-back resource

They reconfigured the equipment in terms of lowest practical maintenance cost, and moved the redundant compressors to stations where they could easily couple as back-ups. Then they implemented an online leak detection and repair program. Finally, they set the replacement compressor to 98 psi, after they determined this delivered the optimum balance between productivity and operating cost.

Since 2008, FUJIFILM has saved 1.2 million kilowatt hours of energy while virtually eliminating compressor system breakdowns. The single compressor is operating at relatively low pressure with attendant benefits to other equipment. It is worth noting that the key to the door was measuring compressed air flow at various points in the system.

Fine-tuning your Operations and keeping our staff Happy with FieldElite

They are the engine that drives your operations, but are you really giving you value for your money? How much time is spent by your personnel on lengthy paperwork and record-keeping, as opposed to actually providing the service to your customers? Manual tasks create bottlenecks and slow your operations, which in turn affects service delivery and customer satisfaction. You want to reach more clients and boost your brand image, growing your market share and generating more revenue. Field Service Management (FSM) software comes in optimise the operations of your mobile workforce, cut down resource wastage, and enhance your productivity as a firm, by actually enabling your field staff to get more done, thus achieving their individual goals. In fact, according to a report published by Fortune Business Insights?, the global FSM market- which stood at $2.29 billion as recently as 2018, will have expanded to $7.27 billion by 2026. What does this mean for your employees, and how do they benefit from FieldElite?

  • Skipping the paperwork with end-to-end automation

Filing reports, keeping track of equipment used, working on the Excel sheets for multiple jobs on a daily basis, all through to the routing and billing- it can be a logistical nightmare. It’s not just about the hours spent poring through documents and typing away at calculators. Manual work exposes you to the risks of human error. Missing records, inaccurate assessments of the situation on the ground due to the overwhelming data streaming in, putting the head office staff under strain- it all hampers the productivity of the company. 

Take scheduling for instance. You have different employees, and various jobs that need their attention, at different locations. It can be a plumbing company whose clients have water filters that need to be repaired, gas boilers inspected, leaking pipes fixed, and others who need new installations to be set up. Assigning your personnel to the different situations will need to take into account the type of job, and the amount of time that it will require, aspects such as the location and the crew that is closest to it. At the head office you will want to keep tabs on the jobs that are in progress, pending, complete, those on hold, and even those that have been cancelled. Running all these through traditional manual processes is enough to drive you to the edge. What’s more, tasks that slip through your fingers amidst the confusion will result in negative feedback from your customers- which you don’t want hitting your brand.

With a field service job management software like FieldELite, you get to handle it all from one dashboard. Optimise your service delivery using the accurate scheduler, that allows you to account for the location of your employees, the status of the job- from the urgent ones like emergency tasks, to the normal duties such as routine maintenance, and low-priority tasks. The field service scheduling software comes with a real-time location feature that allows you to determine the employees closest to the client’s premises who will be appropriate for the job, map out the service areas and give you a birds-eye view of all the operations on the ground, while being updated with the progress of each specific task. Less time is spent travelling to- and from the central office, and more on actually tending to your client’s needs. You can even have situations where you can assign end-of-day tasks to employees who will be passing on that route on their way home.

  • Enhanced resource utilisation that promotes personal and professional development

Skill is key across the industries- from electrical services, solar panel installation, landscaping, home remodelling, pest control, plumbing, HVAC system maintenance, to construction and property management. For the job to be done appropriately and make your clients happy, you want to assign the task to an employee who is particularly proficient at it. This tends to be glimpsed over during manual scheduling since the personnel at the head office will be swamped with so many files, and will pick the first one that comes close to fitting the job description, leading to overlapping of roles. Sure, they may get it done, having seen their colleagues do it and even helping them out when they worked together before on similar projects- but will it be up to the required standard? On the other hand, the FSM allows you to ensure that you get the right technician for the task- who will be more motivated, boosting their performance.

What about accidents? Your employees want to feel safe as they go about their mandate. Many of the field service jobs are hazardous- such as electrical repair jobs, window cleaning tasks at high rise buildings, to elevator repair jobs where a slight glitch can lead to severe ramifications. Field service management software also comes in handy here, where the head office can be notified of any emergency the moment it occurs, and arrange for the necessary action to be taken immediately. That way, your employees will not feel neglected while they are out in the field, showing them that their safety is a priority to your business- which in turn increases their morale. 

  • Readily available knowledgebase and feedback system

When the employees have been assigned a specific job, they will require certain information about it. This includes the scope of the task, history of previous repairs or maintenance that was carried out, accompanying images if needed, risk assessment, any hazards or contaminants that they will need to prepare for, to notes left by technicians who had handled it. Having to keep checking their email, or picking up documents at the office for the day’s job and walking around with them all day as they tend to one customer after another, will slow things down, and not to mention frustrate them. However, the FSM system is directly accessible by the employees via app on their phones. The information needed for each specific task will thus be at their fingertips, speeding up the process and ensuring that they will be ready for each project being handled. 

While carrying out the job itself, the employees will use the very same app to update the system on how it is progressing, chat with the staff at the head office, update the inventory and even place orders for extra parts if necessary. Since mobile service management software apps like FieldElite also work in offline mode, the photos, reports and other entries that are made are collected by the app and saved on the device. Once a network connection is established, they are then updated to the central database- thus ensuring that the job can proceed regardless of the location. 

Once the job is completed, the customer input is also taken, registered in the system through their e-signature. A signoff comment included gives the customer the opportunity to indicate their experience with the job, and the feedback that they would like to provide. In case the job has not been completed, then the scheduling software kicks in, putting it in queue for another appointment to take care of the task, or resolve the issue that had caused it not to be completed the first time. The completed tasks head right to invoicing, which is also handled within the field service management platform, making it a seamless task for the head office staff.

Technology and process improvement

Tightening organisational flow to improve productivity and minimise costs is a growing concern for many businesses post the Global Financial Crisis. Businesses can no longer afford to waste time and personnel on inefficient processes. Organisations using either Six Sigma or Lean techniques better manage their existing resources to maximise product out-put. Both of these techniques involve considerable evaluation of current processes.

What is Six Sigma?

Six Sigma is an organisational management strategy that evaluates processes for variation. In the Six Sigma model, variation equates waste. Eliminating variation for customer fulfilment allows a business to better serve the end-user. In this thought model, the only way to streamline processes is to use statistical data. Each part of a process must be carefully recorded and analysed for variation and potential improvements. The heart of the strategy embodied by Six Sigma is mathematical. Every process is subject to mathematical analysis and this allows for the most effective problem solving.

What is a Lean Model?

Lean businesses do not rely on mathematical models for improvement. Instead, the focus is on reducing steps in the customer delivery cycle, which do not add value to the final deliverable. For example, maintaining excess inventory or dealing with shortages would both be examples of waste behaviour. Businesses that operate using Lean strategies have strong cash flow cycles. One of the best and most famous examples of Lean in action is the Toyota Production System (TPS). In this system, not only is inventory minimised, but physical movement for employees also remains sharply controlled. Employees are able to reach everything needed to accomplish their tasks, without leaving the immediate area. By reducing the amount of movement needed to work, companies also remove wasted employee time.

Industry Applications for Lean and Six Sigma

Lean businesses reduce the number of steps between order and delivery. The less inventory on hand, the less it costs a business to operate. In industries where it is possible to create to order, Lean thinking offers significant advantages. Lean is best utilised in mature businesses. New companies, operating on a youthful model, may not be able to identify wasteful processes. Six Sigma has shown its value across industries through several evolution’s. Its focus on quality of process makes it a good choice for even brand new businesses. The best use is the combination of the two strategies. With the Lean focus on speed and the Six Sigma focus on quality combined, the two organisational processes create synergy. By itself, Lean does not help create stable, repeating success. Six Sigma does not help increase speed and reduce non value-added behaviours. Combined, these two strategies offer incredible value to every business in cost savings.

Using Technology to Implement Lean Six Sigma

Automation processes represent an opportunity for businesses to implement a combination of both Lean and Six Sigma strategies. Any technology that replaces the need for direct human oversight reduces costs and increases productivity. A few examples of potentially cost saving IT solutions include document scanning, the Internet, and automated workflow systems.

  • Document Scanning – Reducing dependency on paper copies follows both Lean and Six Sigma strategies. It is a Lean addition in that it allows employees to access documents instantly from any physical location. It is Six Sigma compliant in that it allows a reduction on process variation, since there is no bottleneck on the flow of information.
  • The Internet – The automation potential offered by the Internet is limitless. Now, businesses can enter orders, manage logistics and perform customer service activities from anywhere, through a hosted portal. With instant access to corporate processes from anywhere, businesses can manage workflow globally, allowing them to realise cost savings from decentralisation.
  • Automated Work Systems – One of the identified areas of waste in any business is processing time. The faster orders are processed and delivered, the greater the profits for the company and the less the expense per order. When orders sit waiting for attention, they represent lost productivity and waste. Automated work systems monitor workflow and alert users when an item sits longer than normal. These systems can also reroute work to an available employee when the original worker is tied up.

Each of these IT solutions provides a method for businesses to either reduce the number of steps in a process or improve the quality of the process for improved customer service.

Identifying Areas for Lean Six Sigma Implementation

Knowing that improved processes result in improved profits, identifying areas for improvement is the next step. There are several techniques for creating tighter processes with less waste and higher quality. Value Stream Mapping helps business owners and managers identify areas of waste by providing a visual representation of the total process stream. Instead of improving single areas for minimal increases in productivity, VSM shows the entire business structure and flow, allowing management to target each area of slow down for maximum improvement in all areas.

Seeing the areas of waste helps management better determine how processes should work to best obtain the desired outcomes. Adding in automated processes helps with improved process management, when put in place with a complete understanding of current systems and their weaknesses. Start with mapping and gain a bird’s-eye view of the situation, in order to make the changes needed for improvement.
