Top 8 Challenges of Big Data and How to Solve Them
As you consider your data integration strategy, keep a tight focus on all end-users, ensuring every solution aligns with the roles and behaviors of different stakeholders. This means that data scientists and the business users who will use these solutions need to collaborate on developing analytical models that deliver the desired business outcomes. End-users must clearly define what benefits they’re hoping to achieve and work with the data scientists to define which metrics best measure the impact on your business. As with any complex business strategy, it’s hard to know what tools to buy or where to focus your efforts without a strategy that includes a very specific set of milestones, goals, and problems to be solved.
Find ways to upskill or reskill staff to save on outsourcing or recruitment costs and open new doors for your team. The challenge then becomes choosing very carefully where to spend money to overcome problems. For IT and tech executives, this is where close alignment with the business becomes critical so the allocated budget matches what’s expected. “Otherwise, you’ll always be allocated a budget that’s insufficient to meet the business initiatives,” says Mike Puglia, chief strategy officer at Kaseya, to CIO.com. Only, the impacts of skills gaps can lead to losses in revenue or business to competitors, increase security risks, and far more. Almost one-third of IT leaders say the rate of technological change is just too fast.
The operational impact is that the administrative cost of maintaining clustered systems is typically nearly proportional to the number of systems you are maintaining, not the size of each one. That means that as their data systems grow, they will be devoting a larger and larger share of their mind to simply dealing with that growth. By a long shot, team communication is the single most important skill for IT leaders, according to 66% of survey respondents.
Working with untrained personnel can result in dead ends, disruptions of workflow, and errors in processing. Before we get into what those challenges are and how you solve them, let’s look at why these challenges exist. Learn about the challenges of big data projects so you can prepare for one and succeed. The self-service analytics specialist’s platform has greatly increased the healthcare organization’s efficiency after its old BI … It’s tempting for data teams to focus on the technology of big data, rather than outcomes. In many cases, Silipo has found that much less attention is placed on what to do with the data.

You probably already feel better knowing that analysts around the world feel the same challenges as you. Remember that different types of organizations may fit with different big data technologies. Just like when choosing the tech stack for your software, the type of big data technology must fit your enterprise needs too. If you want to choose the best big data solution, you should take some technology and functionality considerations into account.
- If your teams can only see a portion of the data, it can lead to poor execution — it could be the reason why your marketing and sales teams are misaligned, or why your customer service department misinterprets a customer’s needs.
- It can be implemented with the help of solutions based on machine learning and artificial intelligence.
- This type of real-world experience is vital for analysts hoping to hone these essential skills and prepare for the realities of the data analytics field in 2022.
- However, not all organizations are able to keep up with real-time data, as they are not updated with the evolving nature of the tools and technologies needed.
- Among the causes, the primary one of data silos is the lack of communication and coordination between different departments within an organization.
According to Statista, the global market of big data is promised to expand in the upcoming years, and perhaps it will hit a record of $68 billion by 2025. Despite the rapid rise in big data adoption and the beneficial applications it brings, many organizations are still struggling to find ways to take full advantage of it. Solutions like self-service analytics that automate report generation or predictive modeling present one possible solution to the skills gap by democratizing data analytics.
While this is not necessarily a bad thing but this technique could be used to change people’s behaviours for somebody else’s own personal needs. For example there have been various documented examples where big data techniques have been used to change people’s voting intensions. These problems are exaggerated by the size of the data, its constant changing nature and the differing formats.
If you start building a big data solution without a well-thought-out plan, you can spend a lot of money storing and processing data that is either useless or not exactly what your business needs. Big data is big, but it doesn’t mean you have to process all of your data. Enterprises also tend to overemphasize the technology without understanding the context of the data and its uses for the business. „Without a data governance strategy and controls, much of the benefit of broader, deeper data access can be lost, in my experience,“ Mariani said. „Many big data initiatives fail because of incorrect expectations and faulty estimations that are carried forward from the beginning of the project to the end,“ he said.

The most important thing is to consider how your business data is structured and fragmented before contacting a vendor. Fortunately, there are organizations that have standardized how big data is protected. In particular, most companies are guided by the NIST Interoperability Framework specifications when implementing big data solutions—where you can find a list of recommendations in the “Security and Privacy” section. When companies implement complex big data systems, they need to be prepared for serious financial costs. These costs start from the development planning stage and end with maintenance and further modernization of systems, even if you implement free software. In addition, you will need to expand your existing staff, which will also result in extra costs.
Often organizations are getting similar pieces of data from different systems, and the data in those different systems doesn’t always agree. For example, the ecommerce system may show daily sales at a certain level while the enterprise resource planning system has a slightly different number. Or a hospital’s electronic health record system may have one address for a patient, while a partner pharmacy has a different address on record.

Many analysts are used to doing data preparation in spreadsheets and finishing a report just in the nick of time, leaving zero energy to tackle tough problems. The good news is that knowing the problem is the first step to kicking it to the curb. Big Data can foster big solutions, but it often comes with its own big headaches. Seemingly small issues that hide in the crevices of your workday are annoying time-suckers — and worse, you get so used to them you forget how painful they really are. As mentioned earlier, Big Data techniques allow one to predict and change people’s behaviors.
It is imperative for the data scientists to communicate effectively with business executives who may not understand the complexities and the technical jargon of their work. If the executive, stakeholder, or the client cannot understand their models, then their solutions will, most likely, not be executed. The most challenging thing about data is not the data itself but understanding how the data relates to the company’s current and future business opportunities. To use big data to find actionable insights about a business, you need to be able to filter through the data and find patterns or trends that can help you make better decisions.
According to a report updated in 2022, 99.5% of collected data was left forsaken and never got used or analyzed. Therefore, vast and rapid data growth definitely results in the greater need for data analytics and business intelligence; this is when the concept of big data analytics shows up and gets hype. The sheer size of Big Data volumes presents some major security challenges, including data privacy issues, fake data generation, and the need for real-time security analytics. Without the right infrastructure, tracing data provenance becomes difficult when working with massive data sets.

Build a safety net so no client loss, staff loss, or data loss causes you to crumble. Even with utmost preparation, processes perfected to the smallest detail, and a nimble approach, you’re still going to encounter obstacles, if not disasters, on the way. No matter the quality of your work, there is typically a lifecycle in an SEO-client relationship.
Silipo cautions against ad hoc integration for projects, which can involve a lot of rework. For the optimal ROI on big data projects, it’s generally better to develop a strategic approach to data integration. Ted Dunning, HPE’s Data Fabric chief technology officer, explains the expected — and unexpected — challenges you’ll face and how your data management practices will change accordingly. As companies drown in data and gain the capability to harness its power, IT professionals must be aware of potential integration and preparation complications.
Finding and Fixing Data Quality Issues
This danger is amplified in an enterprise setting where the big data technologies are deployed alongside existing legacy systems. From cybersecurity risks and quality concerns to integration and infrastructure, organizations face a long list of challenges on the road to Big Data transformation. Big Data along with AI, machine learning, and processing tools that enable real business transformation can’t do much if the culture can’t support them. Overcoming these challenges means developing a culture where everyone has access to Big Data and an understanding of how it connects to their roles and the big-picture objectives.
Many organizations do not have a dedicated team to manage and govern their data. As a result, they struggle to keep up with the ever-changing big data landscape. From science labs to marketing firms, many organizations are grappling with the challenge of turning their enterprise data’s enormous volume and complexity into information that can be turned into insight.
And if you can’t trust your data, you can’t trust the analysis you get from it. But in that same survey, only a little more than a quarter of the companies report that they’ve transformed into a data-driven organization, and only 19% indicate they’ve established a data culture. Many organizations struggle to manage their vast collection of AWS accounts, but Control Tower can help. A generic data lake with the appropriate data structure can make it easier to reuse data efficiently and cost effectively. For example, Parquet files often provide a better performance-to-cost ratio than CSV dumps within a data lake.
Another survey from AtScale found that a lack of Big Data expertise was the top challenge. A Syncsort survey got even more specific; respondents said that the biggest challenge when creating a data lake was a lack of skilled employees. IoT devices increase the potential threat surface by introducing more devices/endpoints to the network. These sensors and devices generate a ton of data and present several opportunities for hackers to gain access to the network. The problem is, managing unstructured data at high volumes and high speeds means that you’re collecting a lot of great information but also a lot of noise that can obscure the insights that add the most value to your organization. Our agile product development solutions advance innovation and drive powerful business outcomes.
In this case, the big data and analytical tools that will be used for its operation need to be adjusted for monitoring and screening the patient’s experience while being in the hospital. Data quality is critical for big data systems, as inaccuracies can lead to inconsistencies, http://tula-samovar.com.ru/544-u-predstavitel-stva-livii-v-pol.html non-reproducible findings, and tough-to-grasp analytics. Even a small percentage of incorrect data affects the bottom line and can cause unanticipated consequences. As mentioned earlier, big data techniques allows one to predict and change people’s behaviours.
Before performing data analysis and building solutions, data scientists must first thoroughly understand the business problem. Most data scientists follow a mechanical approach to do this and get started with analyzing data sets without clearly defining the business problem and objective. However, no career is without its own challenges, and being a data scientist, despite its “sexiness” is no exception. According to the Financial Times, many organizations are failing to make the best use of their data scientists by being unable to provide them with the necessary raw materials to drive results. In fact, according to a Stack Overflow survey, 13.2% of the data scientists are looking to jump ship in search of greener pastures – second only to machine learning specialists.
For example, when different departments of an enterprise use different software and hardware solutions, data leakage or desynchronization may occur. In addition, not all solutions are suitable for an end-to-end integration, so the structure of a big data system turns out to be unnecessarily complex and expensive to maintain. You can use different data science solutions to implement big data—from machine learning to data simulation and business intelligence. If you have never dealt with any of them before, it can be difficult for you to decide on the approach to implementing a big data system. Over time, existing capacity becomes inadequate, and companies must take decisive steps to optimize performance and ensure the resiliency of an expanded system. In particular, the main challenge is to acquire new hardware—in most cases, cloud-based—to store and process new volumes of data.
Big Data Challenges include the best way of handling the numerous amount of data that involves the process of storing, analyzing the huge set of information on various data stores. There are various major challenges that come into the way while dealing with it which need to be taken care of with Agility. Developing stronger teams is a leading challenge for one-quarter of IT decision-makers as they try to fortify their departments with the capabilities to transform their organizations. While technical skills remain in demand, soft skills — we call them Power Skills at Skillsoft — have an elevated importance in today’s workplace. Skills like these make a big impact in team dynamics, especially when fusing teams or working cross-functionally.
