What Sub-Metering did for Nissan in Tennessee

When Nissan built its motor manufacturing plant in Smyrna 30 years ago, the 5.9 million square-foot factory employing over 8,000 people was state of art. After the 2005 hurricane season sky-rocketed energy prices, the energy team looked beyond efficient lighting at the more important aspect of utility usage in the plant itself. Let’s examine how they went about sub-metering and what it gained for them.

The Nissan energy team faced three challenges as they began their study. They had a rudimentary high-level data collection system (NEMAC) that was so primitive they had to transfer the data to spread-sheets to analyse it. To compound this, the engineering staff were focused on the priority of getting cars faster through the line. Finally, they faced the daunting task of making modifications to reticulation systems without affecting manufacturing throughput. But where to start?

The energy team chose the route of collaboration with assembly and maintenance people as they began the initial phase of tracking down existing meters and detecting gaps. They installed most additional equipment during normal service outages. Exceptions were treated as minor jobs to be done when convenient. Their next step was to connect the additional meters to their ageing NEMAC, and learn how to use it properly for the first time.

Although this was a cranky solution, it had the advantage of not calling for additional funding which would have caused delays. However operations personnel were concerned that energy-saving shutdowns between shifts and over weekends could cause false starts. ?We’ve already squeezed the lemon dry,? they seemed to say. ?What makes you think there?s more to come??

The energy team had a lucky break when they stumbled into an opportunity to prove their point early into implementation. They spotted a four-hourly power consumption spike they knew was worth examining. They traced this to an air dryer that was set to cyclical operation because it lacked a dew-point sensor. The company recovered the $1,500 this cost to fix, in an amazing 6 weeks.

Suitably encouraged and now supported by the operating and maintenance departments, the Smyrna energy team expanded their project to empower operating staff to adjust production schedules to optimise energy use, and maintenance staff to detect machines that were running without output value. The ongoing savings are significant and levels of shop floor staff motivation are higher.

Let’s leave the final word to the energy team facilitator who says, ?The only disadvantage of sub-metering is that now we can’t imagine doing without it.?

What is work force management?

For organisations to ensure they provide the right service.  In order to do they need to assign the right employees with the right skills to the right job at the right time to meet demand.

Workforce Management Background

Workforce management (WFM) is a strategy used by companies to increase their efficiency and performance. It entails all activities aimed at maintaining a steady output, such as human resource management, forecasting, field service management, budgeting, scheduling, performance and training management, analytics, recruitment and data collection.

Workforce management utilizes a unique set of performance enhancing tools and software to bolster corporate management, workers, and other categories of managers and supervisors in the manufacturing team, distribution, transportation, and retail operators. This is sometimes called HRM systems, or part of ERP systems, or workforce asset management.

Unlike the conventional outlay that only needed staff scheduling to improve time management, workforce management is now all-inclusive and demand-oriented to optimize staff scheduling. Apart from focusing on demand-orientation and optimization, workforce management also incorporates:

  • Estimating the workload and resource utilisation
  • Job scheduling
  • Management of working times and accounts
  • Monitoring the process of workforce management

Each task should be clearly defined and performed efficiently based on set engineering standards and methods of optimizing each task as much as possible. Out of this framework and demand based forecasts, workers are scheduled and given tasks, performance measured, give feedback, and incentives computed and paid.

Workforce management is an entire scheme aimed at building the capacity of workers, increase productivity and client relations, and where possible reduce labour costs.

What is Mobile Workforce Management (MWM)

Mobile workforce management (MWM) is a software-based service used to oversee employees outside of the institution?s premises; MWM sometimes refers to the field teams. Mobile workforce management encompasses all activities done to monitor and schedule the field workforce.

The entire process includes procurement, management and using mobile devices, applications and computer software. Related support services like tracking, logging, dispatch, productivity management, and other types of communication are also to make it efficient.

Companies do not have the same needs and MWM firms need to fine-tune their software and devices to sufficiently bridge this gap. Some providers are suited only to a specific type of company because of specialization, like managing the electric grid. This experience makes the MWM company suited to provide applications that are relevant to the company for them to continue operating smoothly and efficiently.

With the increase in mobile devices, applications, secured wireless networks and virtual desktop, there comes a stream of opportunities for small and medium-sized businesses (SMB) and other ventures. Nevertheless, a mobile workforce needs better controls, security and support, as well as a functioning mobile workforce management strategy.

MMS (managed mobility services) is often used interchangeably with MWM, but they should not be confused. MWM is related to software and applications used by mobile and computer devices to manage on-field work while MMS focuses on enterprises, and is like a way of keeping in touch with the company, other employees, and linking the mobile while at work to servers and the database.

Benefits of Mobile Workforce Management

MWM allows the utilization of technology to drive productivity. Here are the top five advantages of MWM..

  1. Customer focused. The customer is the backbone of any business. The team needs to keep in touch with up-to-date information about every interaction. In the end, better client relation makes sure that the customer is always happy.
  2. Information has the power to build or destroy. A cloud-based system is easier to manage and can help with collection of data which is used to make business decisions. This can help cut costs, increase the workforce support, and identify areas where polishing needs to be done.
  3. Improved efficiency. Mobile workforce management is majorly used in taskforce allocation. If the company adopts a cloud-based work force management system, allocation is done automatically saving a lot of time.
  4. Increased revenue. Each business seeks to maximize the profit. With cloud-based mobile workforce management some operations like task management, data analysis, customer communication, reporting, and performance monitoring can be automated. This reduces the costs incurred for multiple applications and saves time.
  5. Ease of communication. Communication is vital. Constant communication with customers drives sales rates and everyone loves that. Quick communication will help customers solve their problems faster and get instant feedback.

Additional WFM benefits

 Other WFM benefits are:

  • Operations are made efficient as all complex processes are automated.
  • Employers learn more about worker engagement, productivity and attendance, allowing them to modify training, coaching and processes aimed at streamlining performance.
  • Automation and easy manipulation of data to improve HR, productivity and slash administrative costs.
  • It increases employee productivity by reducing absenteeism and late arrivals.
  • Boosts the morale of employees by encouraging transparency and facilitating manager-employee communication.
  • WFM analyzes market and schedule requirements to pick the right employee with the best set of skills for a certain task.

Companies which embrace workforce management and mobile workforce management have a higher operational efficiency. They have lower operational costs and limit manual work as much as possible

What Heijunka is & How it Smooths Call Centre Production

The Japanese word Heijunka, pronounced hi-JUNE-kuh means ?levelling? in the sense of balancing workflows. It helps lean organizations shift priorities in the face of fluctuating customer demand. The goal is to have the entire operation working at the same pace throughout, by continuously adjusting the balance between predictability, flexibility, and stability to level out demand.

Henry Ford turned the American motor manufacturing industry upside down by mass-producing his iconic black motor cars on two separate production lines. In this photograph, body shells manufactured upstairs come down a ramp and drop onto a procession of cars almost ready to roll in 1913.

Smoothing Production in the Call Centre Industry

Call Centres work best in small teams, each with a supervisor to take over complex conversations. In the past, these tended to operate in silos with each group in semi-isolation representing a different set of clients. Calls came through to operators the instant the previous ones concluded. By the law of averages, inevitably one had more workload than the rest at a particular point in time as per this example.

Modern telecoms technology makes it possible to switch incoming lines to different call centre teams, provided these are multi-skilled. A central operator controls this manually by observing imbalanced workflows on a visual system called a Heijunka Box. The following example comes from a different industry, and highlights how eight teams share uneven demand for six products.

This departure from building handmade automobiles allowed Henry to move his workforce around to eliminate bottlenecks. For example, if rolls of seat leather arrived late he could send extra hands upstairs to speed up the work there, while simultaneously slowing chassis production. Ford had the further advantage of a virtual monopoly in the affordable car market. He made his cars at the rate that suited him best, with waiting lists extending for months.

A Modern, More Flexible Approach

Forces of open competition and the Six Sigma drive for as-close-to-zero defects dictates a more flexible approach, as embodied in this image published by the Six Sigma organisation. This represents an ideal state. In reality, one force usually has greater influence, for example decreasing stability enforces a more flexible approach.

Years ago, Japanese car manufacturer Toyota moved away from batching in favour of a more customer-centric approach, whereby buyers could customise orders from options held in stock for different variations of the same basic model. The most effective approach lies somewhere between Henry Ford?s inflexibility and Toyota?s openness, subject to the circumstances at the moment.

A Worked Factory Example

The following diagram suggests a practical Heijunka application in a factory producing three colours of identical hats. There are two machines for each option, one or both of which may be running. In the event of a large order for say blue hats, the company has the option of shifting some blue raw material to the red and green lines so to have the entire operation working at a similar rate.

Predictability, Flexibility, and Stability at Call Centre Service

The rate of incoming calls is a moving average characterised by spikes in demand. Since the caller has no knowledge whether high activity advisories are genuine, it is important to service them as quickly as possible. Lean process engineering provides technology to facilitate flexibility. Depending on individual circumstances, each call centre may have its own definition of what constitutes an acceptably stable situation.

Reduce Cost and Improve Productivity

Whether the economy is in a downturn or not, management will always aim for a more cost effective IT solution. If your current IT infrastructure is hurting your profitability, our expertise is both ‘tested and proven”.? Also “bleeding edge” solutions in the industry will enable us to find inexpensive alternatives for you.

For instance, have you started to wonder whether having a constantly growing number of servers, many of which are underutilised, is really the norm? Well, that used to be the case. However, with the advent of virtualisation and replication, that expensive exercise is steadily becoming a thing of the past.

By implementing solutions powered by these two technologies, organisations can now manage excess storage capacities and hardware resources by performing simpler processes at lesser costs. In addition to that, using the same pair of technologies, companies can also decrease the downtime suffered during maintenance and upgrades.

Thus, at the end of the day, not only do companies stand to reduce expenditures, they can also boost revenues as a result of increased productivity time.

Do we still have other IT solutions that tackle a different set of problems but arrive at the same outcome, i.e. reduced costs + improved productivity = higher profits? You bet we do.

Basically, this is how we’ll help your company arrive at the same winning formula:

  • Provide insights as to where and when changes have to be made. Oftentimes, initiatives to reduce cost and improve productivity are not preceded by the appropriate study especially as with regards to their impact on all departments in the organisation. This usually results in unnecessary duplication of resources, a sure way to increase costs instead.
  • Consolidate and automate. We’ll work within your budget in finding ways to consolidate your applications, hardware, storage, databases, and processes. Then we’ll integrate automation practices to simplify management and maintenance of all these assets. This will substantially free not only your IT infrastructure but also your IT staff, giving them more opportunities to innovate.
  • Create an innovative environment. One of the benefits you gain in having room to innovate is the potential to discover new ways to drive costs even further. A fraction of your savings can then be used to develop even better IT solutions, thus creating a productive cycle: IT solutions > savings and innovation > better IT solutions. Our role is to help you harness your potentials to keep that cycle running.
  • Work to reduce carbon footprint in all your procedures. By ensuring that energy consumption is brought to a minimum in every step you take, you can rest assured that costs have only one way to go – down. Check out our Energy Management Software ecoVaro.
