Machine Learning currently redefining the financial industry: How can CFOs do?

Among the most interesting trends, Machine Learning is shaping up to be one of the next evolution in the transformation of financial industry and one of the top key technology trends in 2017. But how can CFOs unlock the value of Machine Learning to meet their business objectives and improve performance today?

There are many cutting-edge technologies that is transforming the finance - one of the oldest skills that people has developed after shaping the forms of community. The common nature of these innovations is easy access capabilities, faster paced transactions, a smarter customer experience and better business opportunities.

# What is Machine Learning?

Machine Learning is a type of Artificial Intelligence that allows computers to learn and make software applications become more accurate in predicting outputs without being explicitly programmed. It is the product of established statistical theory in computing power. The basic premise of Machine Learning is to build algorithms that offer businesses the opportunity to transform their operations and their services.

These algorithms are often categorized as being supervised or unsupervised. They learn by analyzing very large volumes of quantitative and qualitative historical data, looking for patterns and trends across hundreds of variables at the highest speeds.

# Four ways CFOs can unlock value

1. Identify areas of machine-induced improvement

Businesses must continually make choices about pursuing new business opportunities. Because an investment in one area requires savings in another. Machine learning helps companies increase savings by taking automation to a much higher level than previously possible.

In many companies, for instance, a high percentage of staff still perform transnational tasks such as like procure-to-pay, order-to-cash, and record-to-report, that can be completed faster and with fewer people through machine learning.

2. Create a learning culture

The value in machine learning is about gaining control and using analytics to expand the business, which is a fundamental job of finance. It can transform your finance organization to be a more strategic partner to the business. At the same time, you need to think about how to train and develop the career paths of your staff. By cultivating an engaged workforce, your company and its people can be more agile, flexible and open to change.

3. Keep finance in your organization’s digital strategy

Unlocking the value of machine learning in finance is tied to your business’s digital strategy. CFOs need to start taking part in the company’s discussions about digital transformation (1). For some organization, there’s a lot of talk in public about the pursuit of a digital journey. CFOs need to help solidify the company’s digital strategy so that when a business case is up for review, you’re well-informed and can make the right decisions.

4. Understand the importance of a digital core

An organization’s digital strategy sets a course for how the enterprise uses technology to enable competitive advantages in the digital economy. Machine learning has played a key role in an effective digital strategy.

Machine learning is dependent upon live, integrated business data. Therefore, to fully embrace machine learning, enterprises need to run on a digital core (2) that is connected, intelligent, responsive, and predictive.

Do You Know About Project Management Myth

Everyone has been duped. Duped into believing there is a “Body of Knowledge” or a “ScrumMaster” or any number of things related to IT project management. There is no Project Managment. There is task management. A project doesn’t keep changing - it remains amorphous from initiation through delivery. You have tasks, and you manage those, along with people, expectations, budget, and really everything besides the project. The project is just what people talk about in to have a common reference point. They can only directly talk about tasks, deadlines, and other empirical data/things. A project is a cloud without clear edges, and it moves, this way… then that. Sometimes it is by design, but sometimes it is not.

There is no such thing as Project Management


Ayer said if it cannot be proven true or false through experience, it is a nonsensical statement. I think considering a project anything more than a bucket of tasks, people, meetings, and assorted ceremony is nonsensical. You have your phases, milestones, meetings, UAT sessions in one for or another regardless of the underlying PLC, but what does this really mean? Project start, do, and end. There are things that people look to in order to recognize a given effort. People need to communicate to make that happen. Ultimately, the effort either passes the test, fails the test, or falls somewhere in between and there is an uncomfortable call where you and the Client try to determine what is fair. Wouldnt it be obvious?




An Agile SDLC removes the need for the “classic” PM and GANTT charts (thank God). However, a Scrum Master is not enough (that’s another sham… pay $1200 and you get certified. No test, no obstacle course, just pay and get the stamp - and yet somehow, people eat it up).

You need someone with common sense and communication skills who isn’t afraid to ask questions and is, above all else, good at finding answers and not emotionally attached to anything but (and this is not mandatory) the Process and Excellence. Why be emotionally attached to the Process? If you have to ask, I don’t think I can explain it to you. You either love delivering good working software or it’s a job. It can be both at times, but the passion is what makes you great. If you don’t want to be great at whatever your chosen discipline is, I don’t understand you, but know you are out there in vast numbers.

Emotion is key in Project Management and Software Development. You have to care. You have to really give a damn. Day to day, decisions are made pragmatically, but that pragmatism is a tool leveraged by the passionate. Or at least, it should be, in my opinion.

Define features, assign priorities to them, practice RIP or RAD or just plain old iterations and while you do UAT, let the client prioritize and re-prioritize and add features all they want because in the end, it is their baby. You want it to be yours, and it might feel like yours, but you are babysitting. I dont know… maybe you are delivering. In my finer moments, I like to believe you are performing magic and manifesting chances for ephemeral excellence, otherwise lost in the mist (or something similarly eerie).

Project Management isn’t about deadlines. It is about delivery. There is a big difference - just like software isn’t made of activities, but it is made of features. Management becomes a means to an end and not a science unto itself beyond the fact that it must include an inherent ability to turn itself into something else. What is good for the goose might not be good for the gander. Still, we can try to lump them together for sake of expedience and to sell books on The Process. We impose things like deadlines and estimates to give the illusion of control. While deadlines and estimates can be marginally effective, they will never be as effective as passion for Process.

People point to Parkinson’s Law and claim that workers somehow manage to take all the time they can to fulfill a task.This is only rarely true. More often, people complete a task in as much time as required. It is simply the definition of what required means that can lead to varied results. Process is malleable. Process is not a set of phases and it is not a template approach. It is different for each project, each organization, and it will possibly change mid-stream. Process is not pre-defined. It is defined as you go, like your System, and in the end, the code is the functional spec (the path you take is the Path). I have found it best to let the Project reveal it’s Process.

Some sculptor I should know the name of but don’t said that he simply removed the excess marble from the statue. I like that Ida. Of course, you have to know how to recognize the signs that something is unclear, iterative, risky, costly, or otherwise noteworthy and be prepared to nudge it along and steer it. However, there can be no didactic System of Project Management. In fact, as I said earlier, there can be no true Project Management. There can only be work, workers, money, expectations, and the like. This is not a bad thing. Not at all. And I think the IT community is coming to realize that Project Managers cannot be certified but by experience.

“If you aren’t making mistakes, you’re not making enough decisions.”

I hope you are all well. Sorry I had to disable comments. I don’t like forcing people to register and to be honest, enough of you email me that I don’t see a need for comments.  I am quite happy to discuss, but that is because I like this stuff and want to learn something as often as possible. I do not use this blog to generate business, expressly. I use it to learn. It is, right now, part of my Process. You can say I am being very literal, but really… take a look at that GANTT chart from day 1 and compare it to the chart on day 100. Where is the project? In both, in between, and probably calling on the phone to find out when the mail merge feature is going to be ready because the bonus letters need to go out yesterday
