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.

What Is Technical Debt? A Complete Guide

You buy the latest iPhone on credit. Turn to fast car loan services to get yourself those wheels you’ve been eyeing for a while. Take out a mortgage to realise your dream of being a homeowner. Regardless of the motive, the common denominator is going into financial debt to achieve something today, and pay it off in future, with interest. The final cost will be higher than the loan value that you took out in the first place. However, debt is not limited to the financial world.

Technical Debt Definition

Technical debt – which is also referred to as code debt, design debt or tech debt – is the result of the development team taking shortcuts in the code to release a product today, which will need to be fixed later on. The quality of the code takes a backseat to issues like market forces, such as when there’s pressure to get a product out there to beat a deadline, front-run the competition, or even calm jittery consumers. Creating perfect code would take time, so the team opts for a compromised version, which they will come back later to resolve. It’s basically using a speedy temporary fix instead of waiting for a more comprehensive solution whose development would be slower.

How rampant is it? 25% of the development time in large software organisations is actually spent dealing with tech debt, according to a multiple case study of 15 organizations. “Large” here means organizations with over 250 employees. It is estimated that global technical debt will cost companies $4 trillion by 2024.

Is there interest on technical debt?

When you take out a mortgage or service a car loan, the longer that it takes to clear it the higher the interest will be. A similar case applies to technical debt. In the rush to release the software, it comes with problems like bugs in the code, incompatibility with some applications that would need it, absent documentation, and other issues that pop up over time. This will affect the usability of the product, slow down operations – and even grind systems to a halt, costing your business. Here’s the catch: just like the financial loan, the longer that one takes before resolving the issues with rushed software, the greater the problems will pile up, and more it will take to rectify and implement changes. This additional rework that will be required in future is the interest on the technical debt.

Reasons For Getting Into Technical Debt

In the financial world, there are good and bad reasons for getting into debt. Taking a loan to boost your business cashflow or buy that piece of land where you will build your home – these are understandable. Buying an expensive umbrella on credit because ‘it will go with your outfit‘ won’t win you an award for prudent financial management. This also applies to technical debt.

There are situations where product delivery takes precedence over having completely clean code, such as for start-ups that need their operations to keep running for the brand to remain relevant, a fintech app that consumers rely on daily, or situations where user feedback is needed for modifications to be made to the software early. On the other hand, incurring technical debt because the design team chooses to focus on other products that are more interesting, thus neglecting the software and only releasing a “just-usable” version will be a bad reason.

Some of the common reasons for technical debt include:

  • Inadequate project definition at the start – Where failing to accurately define product requirements up-front leads to software development that will need to be reworked later
  • Business pressure – Here the business is under pressure to release a product, such as an app or upgrade quickly before the required changes to the code are completed.
  • Lacking a test suite – Without the environment to exhaustively check for bugs and apply fixes before the public release of a product, more resources will be required later to resolve them as they arise.
  • Poor collaboration – From inadequate communication amongst the different product development teams and across the business hierarchy, to junior developers not being mentored properly, these will contribute to technical debt with the products that are released.
  • Lack of documentation – Have you launched code without its supporting documentation? This is a debt that will need to be fulfilled.
  • Parallel development – This is seen when working on different sections of a product in isolation which will, later on, need to be merged into a single source. The greater the extent of modification on an individual branch – especially when it affects its compatibility with the rest of the code, the higher the technical debt.
  • Skipping industrial standards – If you fail to adhere to industry-standard features and technologies when developing the product, there will be technical debt because you will eventually need to rework the product to align with them for it to continue being relevant.
  • Last-minute product changes – Incorporating changes that hadn’t been planned for just before its release will affect the future development of the product due to the checks, documentation and modifications that will be required later on

Types of Technical Debt

There are various types of technical debt, and this will largely depend on how you look at it.

  • Intentional technical debt – which is the debt that is consciously taken on as a strategy in the business operations.
  • Unintentional technical debt – where the debt is non-strategic, usually the consequences of a poor job being done.

This is further expounded in the Technical Debt Quadrant” put forth by Martin Fowler, which attempts to categorise it based on the context and intent:

Final thoughts

Technical debt is common, and not inherently bad. Just like financial debt, it will depend on the purpose that it has been taken up, and plans to clear it. Start-ups battling with pressure to launch their products and get ahead, software companies that have cut-throat competition to deliver fast – development teams usually find themselves having to take on technical debt instead of waiting to launch the products later. In fact, nearly all of the software products in use today have some sort of technical debt.

But no one likes being in debt. Actually, technical staff often find themselves clashing with business executives as they try to emphasise the implications involved when pushing for product launch before the code is completely ready. From a business perspective, it’s all about weighing the trade-offs, when factoring in aspects such as the aspects market situation, competition and consumer needs. So, is technical debt good or bad? It will depend on the context. Look at it this way: just like financial debt, it is not a problem as long as it is manageable. When you exceed your limits and allow the debt to spiral out of control, it can grind your operations to a halt, with the ripple effects cascading through your business.

 

How Mid-South Metallurgical cut Energy Use by 22%

Mid-South in Murfreesboro, Tennessee operates a high-energy plant providing precision heat treatments for high-speed tools – and also metal annealing and straightening services. This was a great business to be in before the energy crisis struck. That was about the same time the 2009 recession arrived. In no time at all the market was down 30%.

Investors had a pile of capital sunk into Mid-South?s three facilities spread across 21,000 square feet (2,000 square meters) of enclosed space. Within them, a number of twenty-five horsepower compressors plus a variety of electric, vacuum and atmospheric furnaces pumped out heat 27/7, 52 weeks a year. After the company called in the U.S. Department of Energy for assistance, several possibilities presented.

Insulate the Barium Chloride Salt Baths

The barium chloride salt baths used in the heat treatment process and operating at 1600?F (870?C) were a natural choice, since they could not be cooled below 1200?F (650?C) when out of use without hardening the barium chloride and clogging up the system. The amount of energy taken to prevent this came down considerably after they covered and insulated them. The recurring annual electricity saving was $53,000.

Manage Electrical Demand & Power

The utility delivers 480 volts of power to the three plants that between them consume between 825- and 875-kilowatt hours depending on the season. Prior to the energy crisis Mid-South Metallurgical regarded this level of consumption as a given. Following on the Department of Energy survey the company replaced the laminar flow burner tips with cyclonic burner ones, and implemented a number of other modifications to enhance thermal efficiency further. The overall natural gas reduction was 20%.

Implement Large Scale Site Lighting Upgrade

The 24/7 nature of the business makes lighting costs a significant factor. Prior to the energy upgrade this came from 44 older-type 400-watt metal halide fixtures. By replacing these with 88 x 8-foot (2.5 meter) fluorescent fittings Mid-South lowered maintenance and operating costs by 52%

The Mid-South Metallurgical Trophy Cabinet

These three improvements cut energy use by 22%, reduced peak electrical demand by 21% and brought total energy costs down 18%. Mid-South continues to monitor energy consumption at each strategic point, as it continues to seek out even greater energy efficiency in conjunction with its people.

Top 10 Benefits of Using Field Service Automation Software

Just how much wastage is witnessed in your operations? Each morning your technicians report to work, they receive the day?s schedule, go through the inventory for the parts and tools that will be required, collect and fill the paperwork, before finally hitting the road- translating to hours of manual organisation. What of the information they need when they are at the site? Are they carrying around bulky files on each individual customer? Your field technicians are also responsible for lots of the equipment being handled- and you want to keep a tab on it all- knowing what is being worked on, when it is happening, how long it takes, and the materials that have been used. Dealing with all this on your end through loads of Excel sheets, calculating and updating time logs, and ticking off the inventory- it can be a strain. Field Service Automation Software comes in to handle it all- from the scheduling and tracking, to inventory control and invoicing- all on the same platform.

Eliminating the Paperwork and Optimising Your Operations

There has been a surge in demand for all-in-one Field Service Management (FSM) solutions. They leverage the power of mobile technology, cloud computing and social collaboration to boost the efficiency of field services. In fact, the FSM market is growing at rates never seen before, if the recent statistics are anything to go by. According to the latest estimates, it is worth $3.5 billion and is expected to hit $5.9 billion by 2024.

It’s understandable why this is happening. Technology is advancing, and we all know it’s every entrepreneur?s dream to optimise the use of the available resources while guaranteeing customer satisfaction. If technology can deliver this through automation, why not? Every business now wants to automate things, and the focus is to maximise resource output. You should, therefore, not be surprised to see the FSM software industry booming. If you just considered the field service industry, you’ll realise that there are so many software applications to help with service automation, whether full or partial.

A good example is FieldElite, which helps with the management of field workers. From your desktop or the palm of your hands, on a tablet or smartphone, you can take full control of your field workers, manage scheduled jobs, and use maps to manage work assignments for the already dispatched field workers. Not only does FieldElite help you handle tasks in an accountable manner but also provides options for accounting and reports, all managed in an easy to use dashboard.

10 Benefits Field Service Automation Software Brings On Board

Why would organisations need to invest in a Workforce management app? Below are some of the key benefits of using a Field Service Management software:

1. Cut down the down-time and make every minute count

From scheduling your operations, mapping out preferred routes, dispatching the service team, to staying connected with them throughout the tasks, you get to improve worker efficiency with field service software like FieldElite. 

Most FSM software programs allow the administrator to send tasks directly to the field worker?s mobile. More often than not, the FSM software provides vital information, including service history, optimal route to the site, the tools required, and contact numbers, among other details.

This improves efficiency by ensuring that the client’s needs are taken care of promptly. Where it’s about machine maintenance, the downtime would be as short as possible.

2. Enhance professionalism and boost your brand image

FSM software programs are known for ensuring professionalism in the manner in which business activities are conducted. Of course, professionalism is attained through several factors, including working with a team of professionals. Such a team, using FSM software, results in enhanced efficiency and excellence.

A field service software like FieldElite helps you to consolidate all your business information into a single central database. With different access levels, your employees will access only as much information as is relevant to their respective duties.

An FSM software is ideal because the stored information can be accessed from any location, meaning field workers can pick new tasks while in the field, provided they’ve got the requisite tools. Instead of having to come back to the office, the employee would access all the information and execute the necessary task.

3. Resource Optimisation with Real-time Field Service Automation Software

Resource optimisation is one of the key determinants of a company?s profitability. While businesses vary in size and purpose, they all share one thing in common ? the desire to increase productivity while ensuring the optimal usage of resources.

Besides productivity, field service software also allows for efficient utilisation of the available resources to cut down on costs.

4. Stay connected with all your crew- and coordinate them better

FSM software facilitates improved coordination with the workforce. The software streamlines the management of the entire field service life cycle, ranging from labour to work orders, returns, contracts, warranties, and equipment.

The idea is to bring all the company?s field-related operations to a central point. And now, with easy data accessibility from a central platform, improved coordination is easily achievable.

5. Get accurate data and make well-informed decisions every step of the way

Adopting the field service management software is more than just a way to improve efficiency. It goes a long way towards improving a company?s accuracy. When a field service management software is used to trace a company?s activities, all the tasks are tracked on the mobile device, keeping the managers informed of every step.

Besides, the technicians also have a free reign to record the diagnostics, quality information, test results, and the parts consumed. All the information can be captured using text, audio, videos, and still photos. This guarantees minimal to no instances of data manipulation.

6. Improve Customer Satisfaction: Win Their Loyalty

Field service management software improves customer satisfaction. How does that happen? Well, using a field service software like FieldElite allows for quick response to customer queries. If there?s one thing that quickly turns your customers off, it’s delayed response to their requests. With the field service management software, however, you can respond to such requests quickly and effortlessly.

Moreover, your customers can also track the service engineer to ensure they’re well informed of any anticipated delays. With quick response time, customer machines have more reliable up-time, which is the desire of every client.

7. Flexibility ? because no one likes being tied down

If there?s one thing that customers like when dealing with a company, it’s flexibility. Instinctively, customers will always want different options to choose from when using a service without appearing to be confined to one provision. Having limited options would also appear boring.

To this extent, it would be wiser to adopt advanced FSM software. Advanced FSM software is compatible with mobile phones, meaning users can easily manage their tasks from isolated locations. FSM software can either be device-agnostic or device-specific. The device-specific type supports Android, Windows, and Apple iOS. This guarantees mobile-friendly tasks where users can easily manage the assignments via mobile application.

8. Store client history in secure cloud-based FSM software

Software like FieldElite stores client history precisely. All the past data, including order history, are stored separately and accurately. In so doing, the field technician gets easy access to the tools, specifications, and technician instructions that aid them in their operations. The result is increased productivity and on-time service delivery.

9. Asset Management and Inventory Control

Naturally, companies offering different repair services have plenty of assets to store. Accordingly, retrieving a specific part out of the large collection would be daunting.

With a field service application like FieldElite, the staff members can track down all the products effortlessly using the GPS. Furthermore, the FSM software ensures excellent maintenance of assets.

10. Improve oversight of field workers ? and keep them in the loop

The FSM software comes with many useful tools, including a built-in GPS tracker. The GPS tracker oversees the operations of the on-field workers, providing precise details about their geographical location, actual arrival time, and most importantly, the distance from the job site.

While this might not be useful at all times, it comes in handy when you need to assign an urgent task to the nearby technician. Call it a classic example of dynamic scheduling.

Final Thoughts

With so much at stake, it’s increasingly compelling to include the Field Service Management Software in your business. With every industry moving towards automation, your business cannot afford to lag.

Quick and efficient service delivery through FSM software may be the difference between you and your competitors.

The FSM software is no longer the cherry on the cake but a must-have tool for your survival in the highly competitive market.
