How DevOps oils the Value Chain

DevOps ? a clipped compound of development and operations – is a way of working whereby software developers are in a team with project beneficiaries. A client centred approach extends the project plan to include the life cycle of the product or service, for which the software is developed.

We can then no longer speak of a software project for say Joe?s Accounting App. The software has no intrinsic value of its own. It follows that the software engineers are building an accounting app product. This is a small, crucially important distinction, because they are no longer in a silo with different business interests.

To take the analogy further, the developers are no longer contractors possibly trying to stretch out the process. They are members of Joe?s accounting company, and they are just as keen to get to market fast as Joe is to start earning income. DevOps uses this synergy to achieve the overarching business goal.

A Brief Introduction to OpsDev

You can skip this section if you already read this article. If not then you need to know that DevOps is a culture, not a working method. The three ?members? are the software developers, the beneficiaries, and a quality control mechanism. The developers break their task into smaller chunks instead of releasing the code to quality control as a single batch. As a result, the review process happens contiguously along these simplified lines.

This is a marked improvement over the previously cumbersome method below.

Write the Code ? Test the Code ? Use the Code
? Evaluate, Schedule for Next Review ?

Working quickly and releasing smaller amounts of code means the OpsDev team learns quickly from mistakes, and should come to product release ahead of any competitor using the older, more linear method. The shared method of working releases huge resources in terms of user experience and in-line QC practices. Instead of being in a silo working on its own, development finds it has a richer brief and more support from being ?on the same side of the organisation?.

The Key Role that Application Program Interfaces Play

Application Program Interfaces, or API?s for short, are building blocks for software applications. Using proprietary software-bridges speeds this process up. A good example would be the PayPal applications that we find on so many websites today. API?s are not just for commercial sites, and they can reduce costs and improve efficiency considerably.

The following diagram courtesy of TIBCO illustrates how second-party applications integrate with PayPal architecture via an API fa?ade.

The DevOps Revolution Continues ?

We close with some important insights from an interview with Jim Stoneham. He was general manager of the Yahoo Communities business unit, at the time Flickr became a part. ?Flickr was a codebase,? Jim recalls, ?that evolved to operate at high scale over 7 years – and continuing to scale while adding and refining features was no small challenge. During this transition, it was a huge advantage that there was such an integrated dev and ops team?

The ?maturity model? as engineers refer to DevOps status currently, enables developers to learn faster, and deploy upgrades ahead of their competitors. This means the client reaches and exceeds break-even sooner. DevOps lubricates the value chain so companies add value to a product faster. One reason it worked so well with Flickr, was the immense trust between Dev and Ops, and that is a lesson we should learn.

?We transformed from a team of employees to a team of owners. When you move at that speed, and are looking at the numbers and the results daily, your investment level radically changes. This just can’t happen in teams that release quarterly, and it’s difficult even with monthly cycles.? (Jim Stoneham)

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.

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.

Are Master Data Management and Hadoop a Good Match?

Master Data is the critical electronic information about the company we cannot afford to lose. Accordingly, we should sanitise it, look after it, and store it safely in several separate places that are independent of each other. The advent of Big Data introduced the current era of huge repositories ?in the clouds?. They are not, of course but at least they are remote. This short article includes a discussion about Hadoop, and whether this is a good platform to back up your Master Data.

About Hadoop

Hadoop is an open-source Apache software framework built on the assumption that hardware failure is so common that backups are unavoidable. It comprises a storage area and a management part that distributes the data to smaller nodes where it processes faster and more efficiently. Prominent users include Yahoo! and Facebook. In fact more than half Fortune 50 companies were using Hadoop in 2013.

Hadoop – initially launched in December 2011 ? has survived its baptism of fire and became a respected, reliable option. But is this something the average business owner can tackle on their own? Bear in mind that open source software generally comes with little implementation support from the vendor.

The Hadoop Strong Suite

  • Free to download, use and contribute to
  • Everything you need ?in the box? to get started
  • Distributed across multiple fire-walled computers
  • Fast processing of data held in efficient cluster nodes
  • Massive scaleable storage you are unlikely to run out of

Practical Constraints

There is more to Hadoop than writing to WordPress. The most straightforward solutions are uploading using Java commands, obtaining an interface mechanism, or using third party vendor connectors such as ACCESS or SAS. The system does not replace the need for IT support, although it is cheap and exceptionally powerful.

The Not-Free Safer Option

Smaller companies without in-depth in-house support are wise to engage with a technical intermediary. There are companies providing commercial implementations followed by support. Microsoft, Amazon and Google among others all have commercial versions in their catalogues, and support teams at the end of the line.
