8 Best Practices To Reduce Technical Debt

When past actions in software development return to haunt you…

Is your business being bogged down by technical debt? Let’s look at measures that you can take to reduce it and scale your operations without the weight pulling you back. 

 

Work with a flexible architecture.

Right from the word go, you want to use architecture whose design is malleable, especially with the rapid rate of software evolution witnessed today. Going with an architecture that keeps calling for too much refactoring, or whose design won’t accommodate future changes will leave you with costly technical debt. Use scalable architecture that allows you to modify or add new features in future releases. While on this, complex features required in the final product should be discussed at the planning stage, that way simplified solutions that will be easier to implement can be identified, as this will lead to less technical debt in the long run. 

 

The Deal with Refactoring 

This is basically cleaning up the code structure without changing its behaviour. With the updates, patches, and new functionalities that are added to the systems and applications, each change comes with the threat of more technical debt. Additionally, organisations are increasingly moving their IT infrastructure from on-premises facilities to colocation data centres and deploying them on the cloud. In such scenarios, some workarounds are often needed to enable the systems to function in the new environments, which they hadn’t been initially developed to accommodate. Here, you will need to take some time to refactor the existing system regularly, streamlining the code and optimizing its performance – and this will be key to pay down the tech debt. When working with a flexible architecture from the start, the amount of work that goes into this will be reduced, meaning there’ll be less tech debt involved. 

 

Run discovery tests

Discovery testing essentially takes place even before a line of code is written for the system or application. This takes place at the product definition stage, where human insight software is used to understand the needs of the customer and is particularly helpful in setting priorities for the development work that will be carried out. It gives your business the opportunity to minimize the technical debt by allowing customers to give you a roadmap of the most pertinent features desired from the product. 

 

Routine code review

Getting a fresh look at the product or application from different sets of eyes in the development team will improve the quality of the code, thus reducing technical debt. There’s a catch though – this should be planned in a convenient way that doesn’t end up becoming a burden for the developers. Here are suggestions:

Break down pull requests

Instead of having complex pull requests where numerous changes in the code are introduced at a go, have this broken down into smaller manageable pull requests, each with a brief title and description about it. This will be easier for the code reviewer to analyse. 

● Define preferred coding practices

Documenting the preferred coding style will result in cleaner code, meaning the developers will focus their effort on reviewing the code itself, not losing time on code format debates.

 

Test automation

Relying only on scheduled manual testing opens you up to the risk of technical debt accruing rapidly, and not having sufficient resources to deal with the accumulated problems when they are identified. Automated testing on the other hand enables issues to be uncovered quicker, and with more precision. For instance, you can have automated unit tests that look at the functioning of the individual components of a system, or regression testing where the focus is on whether the code changes that have been implemented have affected related components of the system. However, establishing and maintaining automated testing will require quite some effort – making it more feasible for the long-term projects.

 

Keep a repository that tracks changes made

Do you have a record of changes made in the software? Keeping one in a repository that is accessible by the development team will make it easy to pin-point problems at their source. For instance, when software is being migrated to a new environment, or legacy software is in the process of being modernised, you will want to have an accurate record of changes that are being introduced, that way if there is an undesired impact on the system this it will be easier to zero-down on the cause.

 

Bring non-technical stakeholders on board

Does this conversation sound familiar?

Development Team: “We need to refactor the messy code quickly”

Product Team: “We have no idea what you are saying”

On one hand, you have the management or product team defining the product requirements, creating a project roadmap, and setting its milestones. On the other hand, there’s the software development/engineering that’s primarily focused on the product functionality, technical operations and clearing the backlog in code fixes. Poor communication between the two teams is actually a leading cause of technical debt.

For you to take concrete steps in managing your technical debt, the decision-makers in the organisation should understand its significance, and the necessity of reducing it. Explain to them how the debt occurred and why steps need to be taken to pay it down – but you can’t just bombard them with tech phrases and expect them to follow your thought process. 

So how do you go about it? Reframe the issues involved with the technical debt and explain the business value or impact of the code changes. Basically, the development team should approach it from a business point of view, and educate the management or production team about the cost of the technical debt. This can include aspects such as expenses in changing the code, salaries for the software engineers especially when the development team will need to be increased due to the workload piling up, as well as the revenue that is lost when the technical debt is allowed to spiral. 

The goal here is to show the management or production team how issues like failing to properly define the product requirements will slow down future software development, or how rushing the code will affect the next releases. That way, there will be better collaboration between the teams involved in the project. 

 

Allocate time and resources specifically for reducing technical debt

With management understanding that working with low-quality code is just like incurring financial debt and it will slow down product development, insist on setting time to deal with the debt. 

For instance, when it comes to the timing of application releases, meetings can be conducted to review short- and longer-term priorities. These meetings – where the development team and product team or management are brought together, the developers point out the software issues that should be resolved as a priority as they may create more technical debt. Management then ensures that budgets and plans are put in place to explicitly deal with those ongoing maintenance costs.

 

Retire old platforms

While most of the resources are going into developing new applications and improving the systems being used, the organisation should also focus on retiring the old applications, libraries, platforms, and the code modules. It’s recommended that you factor this into the application release plans, complete with the dates, processes and costs for the systems involved. 

 

Total overhaul

When the cost and effort of dealing with the technical debt far outweighs the benefits, then you may have to replace the entire system. At this tipping point, you’re not getting value from the technical debt, and it has become a painful issue that’s causing your organisation lots of difficulties. For instance, you may be dealing with legacy software where fixing it to support future developments has simply become too complicated. The patches available may only resolve specific issues with the system, and still leave you with lots of technical debt. Here, the best way out is to replace the system in its entirety. 

 

Final thoughts

Every software company has some level of tech debt. Just like financial debt, it is useful when properly managed, and a problem when ignored or allowed to spiral out of control. It’s a tradeoff between design/development actions and business goals. By taking measures to pay down your organization’s debt and address its interest as it accrues, you will avoid situations where short term solutions undermine your long-term goals. This is also key to enable your business to transition to using complex IT solutions easier, and even make the migration between data centres much smoother. These 8 measures will enable you to manage your technical debt better to prevent it from being the bottleneck that stifles your growth.

How Armstrong World Industries is going Cradle-to-Cradle

The Cradle-to-Cradle concept holds that human effort must be biometric, in other words enrich the environment within which it functions as opposed to breaking it down. This means manufacturing must be holistic in the sense that everything is reusable and nothing is destroyed. Armstrong World Industries was the first global mineral ceiling tile manufacturer to achieve Cradle-to-Cradle certification. We decided to take a closer look at how they achieved this.

Armstrong Worldwide Industries has five plants in the UK alone. These produce an annual turnover of ?2.7 billion. They have been making ceilings for more than 150 years. Fifteen years ago and way ahead of the curve it started recycling, and has maintained a policy of not charging contractors for waste ever since. Along the way, it developed a product that can be re-used indefinitely.

The Challenge

Going green must also be commercially sustainable. In Armstrong?s case, it faced a rise in landfill tax from ?8 per tonne per year to ?80 per tonne per year. This turned the financial cost of waste from a nuisance to a threat. It calculated that recycling one tonne of ceiling materials would:

  • Eliminate 456kg of CO2 equivalents by saving 1,390 kWh of electricity
  • Preserve 11 tons of virgin material and save 1,892 gallons of potable water

They hoped to extend their own recycling project by asking demolition and strip-out contractors to join it, so they could reprocess their scrap as new batches of tiles too.

The Achievement

As things stand today, an Armstrong ceiling tile now contains an average of 82% recycled content. Indeed, if they could find more ceilings to recycle this could reach 100%. In the past two years alone, Armstrong Worldwide Industries UK has saved 130,399m? of greenfield from landfill, being the equivalent of 520 skips that would otherwise have cost contractors over ?88,000 to dispose of.

The Broader Context

Armstrong Worldwide Industries is a global leader in water management, and is bent on minimising its reliance on fossil for energy. It has implemented online measurement systems that feed data to its corporate environmental, health and safety system. This empowers it to produce reports, track corrective actions and measure progress towards its overall goal of being carbon neutral.

Next time you sit beneath an Armstrong Worldwide Industries panelled ceiling, spare a thought for how much ecoVaro consumption analytics could contribute to your bottom line (and how it would feel to be lighter on carbon too).

ecoVaro to tackle water stress

For many people within the UK, water is not really something to worry about. Surely enough of it falls out the sky throughout the year that it does feel highly unlikely that we?ll ever run out of it. There certainly does seem to be an abundance of Branded Water available in plastic bottles on our supermarket shelves.

Water, water, every where,
And all the boards did shrink;
Water, water, every where,
Nor any drop to drink.

The Rime of the Ancient Mariner ? Samuel Taylor Coleridge

Despite this, Once-unthinkable water crises are becoming commonplace.  If you consider that In England and Wales, we use 16 billion litres of clean drinking water every day ? that’s equivalent to 6,400 Olympic sized swimming pools.

Currently, water companies can provide slightly more than we need ? 2 billion litres are available above and beyond what we’re using.  In some areas, though, such as south east England, there is no surplus and, as such, these regions are more likely to face supply restrictions in a dry year.

If we take little moment to reflect on some of the most notable water related stories over the past few years, we’ll start to get a picture of just how real the potential and the threat of water shortages can be.

Reservoirs in Chennai, India?s sixth-largest city, are nearly dry right now. Last year, residents of Cape Town, South Africa narrowly avoided their own Day Zero water shut-off.

It was only year before that, Rome rationed water to conserve scarce resources.

Climate change is likely to mean higher temperatures which may drive up the demand for water (alongside population growth) and increase evaporation from reservoirs and water courses during spring and summer.

The impact of climate change on total rainfall is uncertain, but the rain that does fall is likely to arrive in heavier bursts in winter and summer. Heavier rain tends to flow off land more quickly into rivers and out to sea, rather than recharging groundwater aquifers.

A greater chance of prolonged dry periods is also conceivable.  This combined with the harsh reality that no human population can sustain itself without sufficient access to fresh water.

If present conditions continue, 2 out of 3 people on Earth will live within a water-stressed zone by 2025

What is water stress?

Water stress is a term used to describe situation when demand for water is greater than the amount of water available at a certain period in time, and also when water is of poor quality and this restricts its usage. Water stress means deterioration in both the quantity of available water and the quality of available water due to factors affecting available water.

Water stress refers to the ability, or lack thereof, to meet human and ecological demand for water. Compared to scarcity, water stress is a more inclusive and broader concept.

Water Stress considers several physical aspects related to water resources, including water scarcity, but also water quality, environmental flows, and the accessibility of water.

Supply and Demand

Major factors involved when water scarcity strikes is when a growing populations demand for water exceeds the areas ability to service that need.

Increased food production and development programs also lead to increased demand for water, which ultimately leads to water stress.

Increased need for agricultural irrigation in order to produce more crops or sustain livestock are major contributors to localised water stress.

Overconsumption

The demand for water in a given population is fairly unpredictable.  Primarily, based on the fact that you can never accurately predict human behaviour and changes in climate.

If too many people are consuming more water than they need because they mistakenly believe that water is freely available and plentiful, then water stress could eventually occur.

This is also linked to perceived economic prosperity of a give region.  Manufacturing demand for water can have huge impact regardless whether water is actively used within the manufacturing process or not.

Water Quality

Water quality in any given area is never static.  Water stress could happen as a result of rising pollution levels having a direct impact on water quality.

Water contamination happens when new industries either knowingly or unknowingly contaminate water with their industrial practices.

Largely, this can happen and frequently does so because these industries do not take effective control of monitoring and managing their impact on communal water supplies.  Incorrectly assuming this is the responsibility of an additional third party like the regional water company.

The truth is, water quality and careful monitoring of it is all of our responsibility.

Water Scarcity

Simple increases in demand for water can in itself contribute to water scarcity. However,  these are often preceded by other factors like poverty or just the natural scarcity of water in the area.

In many instances, the initial locations of towns or cities were not influenced by the close proximity of natural resources like water, but rather in pursuit of the extraction of other resources like Gold, Coal or Diamonds.

For Instance, Johannesburg,  South Africa is the largest City in South Africa and is one of the 50 largest urban areas in the world. It is also located in the mineral rich Witwatersrand range of hills and is the centre of large-scale gold and diamond trade.

Johannesburg is also one of the only major cities of the world that was not built on a river or harbour.   However, it does have streams that contribute to two of Southern Africas mightiest rivers – Limpopo and the Orange rivers.  However, most of the springs from which many of these streams emanate are now covered in concrete!

Water Stress and Agriculture

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of real-time data and utilize cloud-based storage and processing power to curate it.

Sentek?s technology can be found in remote places like Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily repositioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to an end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By accurately monitoring water can be saved until when the plant really needs it.

Peter also emphasises that crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return.

The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us.

Ecovaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

A Quarter of the World?s Population, Face High Water Stress

Data from WRI?s Aqueduct tools reveal that 17 countries ? home to one-quarter of the world?s population?face ?extremely high? levels of baseline water stress, where irrigated agriculture, industries and municipalities withdraw more than 80% of their available supply on average every year. 

Water stress poses serious threats to human lives, livelihoods and business stability. It’s poised to worsen unless countries act: Population growth, socioeconomic development and urbanization are increasing water demands, while climate change can make precipitation and demand more variable.  

How to manage water stress

Water stress is just one dimension of water security. However, like any challenge, its outlook depends on adequate monitoring and management of environmental data.

Even countries with relatively high water stress have effectively secured their water supplies through proper management by leveraging the knowledge they have garnered by learning from the data they gathered.

3 ways to help reduce water stress

In any geography, water stress can be reduced by measures ranging from common sense to innovative technology solutions.

There are countless solutions, but here are three of the most straightforward:

1. Increase agricultural efficiency: The world needs to make every drop of water go further in its food systems. Farmers can use seeds that require less water and improve their irrigation techniques by using precision watering rather than flooding their fields.

Businesses need to increase investments to improve water productivity, while engineers develop technologies that improve efficiency in agriculture.

Consumers can reduce food loss and waste, which uses one-quarter of all agricultural water.

2. Invest in grey and green infrastructure:  D Data produced by Aqueduct Alliance  –  shows that water stress can vary tremendously over the year.  WRI and the World Bank?s research shows that built infrastructure (like pipes and treatment plants) and green infrastructure (like wetlands and healthy watersheds) can work in tandem to tackle issues of both water supply and water quality.

3. Treat, reuse and recycle:  We need to stop thinking of wastewater as waste.

Treating and reusing it creates a ?new? water source.

There are also useful resources in wastewater that can be harvested to help lower water treatment costs. For example, plants in Xiangyang, China and Washington, D.C. reuse or sell the energy- and nutrient-rich byproducts captured during wastewater treatment.

Summary

The data is undeniably clear, there are very worrying trends in water.

Businesses and other other organisations need to start taking action now and investing in better monitoring and management, we can solve water issues for the good of people, economies and the planet. We collectively cannot kick this can down the road any further, or assume that this problem will be solved by others.

It is time, for a collective sense of responsibility and for everyone to invest in future prosperity of our Planet as a collective whole.  Ecological preservation should be at the forefront of all business plans because at the end of the day profit is meaningless without an environment to enjoy it in!

The Connection between Big Data and MDM

Master Data is information that is critical to your business. This could include contracts, proprietary information, intellectual capital and a whole lot more besides. Because this often reposes in a variety of different places, you need a master data management / MDM policy to control it. That way, you can link it all together in a single, secure, backed up file.

This Sounds Like Big Data

Not necessarily: big data refers to extremely large data sets that are best stored and analysed on a cloud using big technology, in order to uncover trends, patterns and associations often relating to human behaviour. Of course, if you run a niche restaurant your critical master data might be limited to a few recipes and the books you do not care to show your accountant.

The distinction is largely a question of size: think of your master data as the subset of big data that you already have your mind around. According to John Case of IBM this is probably already in a structured format and available to share. He goes on to present a cogent case for using this as a peg point around which to systematise the rest. This is because the average organisation already has master data recording customers? and prospects? behaviour.

Do I Still Need My Master Data?

Yes you do, because real people created it with the benefit of human insight. Retain it as a separate set. Then compare it with the results of big data processing for even richer insights. Two heads are better that one and that goes for data processing too.

Trends in CRM Big Data

Adding data via location-aware devices like smartphones and tablets is adding a new dimension to customer information. We now know where they were when they made the enquiry or punched in the information. Use this geo-location data to hone the way you interact with customers and service their accounts. Do not phone a customer who makes decisions at work when they are at home.

Does My Master Data Belong on a Cloud?

There are a number of ?ifs? to consider. How comfortable are you with your service provider. What would happen if someone hacked their server? There are many advantages to cloud technology. Denizon knows of solutions you can rely on, and makes sure its clients have contingency plans to protect them at all times.
