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.
A mobile workforce management software is key to managing an efficient field workforce.? Managing a staff of people can be tricky in any industry. Try keeping track of employees on shifting jobsites, many whom are paid hourly or temporary workers. The added pressure of ensuring the right workers get to the right sites at the right times, but they also need to track hours, parts used, vehicles and equipment assets.
In a previous post, we defined what is an operational review and why they play a key process in the continual evolution of successful businesses.?
Operational reviews allow the organization members to evaluate their performance, according to the procedures, resources properly, timescales and budgets.
In this post, we’ll take a closer look at how to implement an operational review and the steps typically undertaken to help you and your organisation to implement an operational review.
What the steps in a Operational Review Process
There are typically six steps in an operational review that range from preparatory work conducting interviews and collecting documents to the presentation of the final written report.
An audit should be customized to meet a organisatons specific needs, so standard steps can and should only serve as a guideline.? Management and internal and external auditors should adjust the process to address the company’s particular goals and objectives.
Initial Management Meeting
Understanding the problem is the first crucial step of an operational review. This is one of major areas of discussions when the audit team meets with the management, and department heads will be asked to identify any specific areas of concern. Once the problem is identified, it would be easier to come up with workable solutions.
Conduct Interviews
The next step in the evaluation is carried out with experienced teams doing interviews and keeping close observation. Each team essentially watches how employees carry out their responsibilities. This is considered a key part of the process.
When doing the interview, it is also vital that the observing team gains the employees? trust and confidence. Likewise, the staff must be assured that whatever transpires between the team and the employee will be kept confidential. Management must therefore guarantee anonymity to anyone who offers critical information, lest employees withhold vital information and render the data gathered inaccurate.
Systems Review
Employees and management practices will be reviewed by the assessing team according to the standard policies and guidelines of the company. The effectiveness of the controls in place as well as their appropriateness to the current operating conditions will also be evaluated.
Reporting
A documentation of the data gathered and the assessment of the evaluating team, will be submitted to the management after the review process. Flow charts and written narratives of departmental activities are usually part of this report. This is also where observations and recommendations of the team will be presented to the department heads concerned.
Review Results
While the operational review is being conducted, it is important to take into account the vital factors that affect the company: the people, processes, procedures, and strategies. These four factors can determine the company?s progress in the future.
Key Areas of focus in operation reviews
At a minimum an operational review should include the following key ares of assessment
Management Control
Responsibilities, authority, and the scope in which an employee has the freedom to act must be clearly defined and documented. A complete and specific job description for instance, would give the employee a clear perspective on how he acts and functions within the company.
Boundaries should be set not only to benefit the employer but more so the employee as well.
Moral and Ethical Guidelines
Moral and ethical guidelines are just as important to ensure for a smoother employer?employee relationship. Otherwise, personal issues such as work ethics, work attitude and personal values may post problems in the long run if such guidelines are not drawn properly before relationships are established.
Processes and procedures
Evaluating processes is only beneficial if the company itself updates its processes and procedural manuals regularly, or at least when needed. Such protocols may need revision and some steps may be obsolete already. Improving a company?s processes and procedures doesn’t always entail cost. In fact, improvised procedures may even be cost-effective and could make the processes more manageable.
Communication and reporting standards
Gaps in communication could result in serious lapses in internal controls, putting the company and/or its assets at risk. This is where the importance of timely and clear communication comes in. Likewise, reports must be useful, and the flow of information and how it is processed must keep pace with the company?s growth.
Information technology (IT) and security controls can also be included under the communication clause. Proper IT security policies must be in place, state-of-the-art protection techniques employed, and everything be documented, periodically updated, and continually monitored.
Strategic planning and tactics
No company can ever be complete without its strategies. It would unwise for any organization to proceed without first knowing where it stands and what direction it wants to take. Strategic planning draws such a map. It must be aligned to the mission and vision of the company, and should also coincide with the organizational goals set. Strategic planning deals with these three key questions:
What do we do now
Whom do we do it for?
How can we overcome competition
Without clear strategic direction, expectations would likely differ between ownership and management.
Contingency planning, testing and recovery
Contingency plans must be up-to-date, and are essential to the organization. If one course of action fails, the company should have plan B, C and so on. In addition, an organization should be prepared to respond to interference’s.
This includes establishing a formal process to review transactions processing during both disruption and recovery.
Presentation of Report
Based on your objectives and our findings, we will develop detailed recommendations to improve your company?s performance and productivity. Our written report will include a list of both short-term and long-term projected improvements and courses of action, to be mutually agreed upon by both parties.
To ensure the achievement of the improvements we outlined, our team will also assist in the implementation of these modifications.
The plan has three levels of recommendations: one for executives, another for management, and a third one for staff.
The executive summary concentrates on your company?s strengths, weaknesses, opportunities and threats to its entirety. It includes recommendations for any needed changes in policy or governance.
The management plan is based on employee feedback and includes areas of immediate improvement as well as identification of potential problem areas. Concerns from the bottom level management can now be forwarded to the top level management in formal writing. Better working relationships may evolve from this, thereby setting the work environment for a higher productivity ratio.
Lastly, the staff report deals with topics like charting the hierarchy of the organization, and discussing in detail specific control objectives that are critical to the company?s mission. Part of our goal is to encourage personnel to pay close attentions to such changes, if any, as these efforts are essential if they want to bring about both organizational and personal success.
If you would like to further discuss how our operational review services can benefit your company, please feel free to contact us at your convenience to schedule an initial consultation. We?ll be more than happy to assist you.
If only technologists had their way, passwords and PINs would have long been replaced with more innovative (and admittedly, better) security solutions. But such is not the case. Those alternative solutions, which include biometrics, smart cards, and password fobs, effective as they may be, are just way too expensive to implement.
So although passwords and PINs may not be here to stay, they certainly won’t be going away soon either.
Why keeping passwords in memory is no longer possible
A couple of decades ago, it would have been nearly impossible to crack an eight-character password using brute force. Today, however, advancements in computing power are rendering the typical passwords of the past easily decipherable, forcing us to come up with passwords that are not only much longer, but also much more complex and hence difficult to recall.
For instance, memorable words like your favourite character (e.g. ‘skywalker’) may have been acceptable then, but not anymore. Today?s security systems will encourage you to insert numbers or even other keyboard characters as a means to once again counter brute force. Hence, ‘sk5%ywa936lker@#’ may be more acceptable.
Remembering that one alone can be pretty daunting.
To further complicate matters, the number of applications that require passwords for access is much greater than before even for a single end user. Ordinary end users have to keep track of passwords for their email account, network login, workstation login, online services, and so on.
The burden is even greater for your IT admins, who have to remember a larger collection of passwords that protect business critical systems and applications. Clearly, the team in charge of your IT security will need a way to manage all these passwords.
Password management solutions
Existing password management solutions typically come in the form of software applications that store passwords. Basically, all you need to remember are your login details for the app a.k.a. the ?master password?. Once you’ve gained access inside, you can then retrieve any password you stored there.
Some of these apps are installed in portable devices like Pocket PCs, PDAs, or smartphones, which you would normally take along with you. For as long as the device stays with you, your passwords will be in safe hands. What’s more, you can retrieve them anywhere you go.
But obviously, there’s a problem. What if the device gets misplaced or stolen? Although the person who ends up with your device may not be able to gain access into the app and your passwords, neither will you. A better solution would therefore be an app that can be accessed anywhere but is not susceptible to getting lost.
Web-based password manager
A web-based password manager fits the bill. You don’t have to take it with you, but still you can access it almost anywhere. A typical web-based password manager will have all your passwords stored in a centralised, highly secure location.
If you want, you can even use your mobile password manager along with the web-based one. Ideally, your web-based password manager would have a copy of all the end-user passwords as well as the master passwords of your organisation.
With an easy to access but highly-secure web-based password manager, you no longer have to come up with passwords that (ironically) are supposed to be easy to remember but hard to crack at the the same time.
Furthermore, password managers are ideal for keeping passwords that have to be changed every-now-and-then; a requirement that’s becoming all too common in organisations bent on enforcing more stringent controls.
Like it or not, regulations are here to stay and for a company to comply with them, its IT and financial systems will have to be equipped with a suitable control framework. One common stumbling block to such an implementation is a company?s over-reliance on spreadsheets. (more…)
