Companies considering in-house prediction model development projects are rapidly increasing. This is because AI utilization in demand forecasting has become essential rather than optional. As research results continue to show that AI-based demand forecasting accuracy is over 40% higher on average than traditional methods, many companies are joining this trend.

In this situation, companies face important decisions: Should they develop Python-based prediction models directly through their own IT teams, or should they adopt proven AI solutions like Deepflow?

Python has established itself as the most popular programming language for data analysis and machine learning model development. With its rich libraries and developer ecosystem, Python provides various tools necessary for implementing demand forecasting models and is already being utilized by many corporate IT teams. The in-house development approach has the advantage of perfectly reflecting a company's unique business logic and data characteristics.

There are Python libraries for building predictive models, such as pandas, NymPy, matplotlib, seaborn, scikit-learn, etc. There are also functions that make it easier to analyze data and program predictions (source: Exploring data using Pandas — Geo-Python site documentation)

However, the process of IT teams directly developing prediction models using Python can be more complex and lengthy than expected. Numerous challenges exist, including securing specialized personnel such as data scientists and ML engineers, extensive data preprocessing and feature engineering, model training and optimization, and continuous performance improvement and maintenance. This requires fundamental discussions about a company's core competencies and resource allocation.

On the other hand, specialized AI demand forecasting solutions like Deepflow have high-performance models already optimized by industry that can be immediately utilized. These solutions have the advantage of saving time and resources needed for in-house development while providing high-level prediction accuracy. Particularly, Deepflow's approach of providing industry-specialized AI models presents immediate solutions to specific forecasting problems companies face, unlike general prediction models built from scratch with Python.

This article will comprehensively compare two approaches - IT teams' direct Python-based prediction model development and Deepflow solution implementation - across multiple dimensions including cost, time, accuracy, scalability, and maintenance. Through this analysis, we aim to help companies make optimal choices suited to their situations, resources, and business goals, and provide insights for building more efficient and accurate demand forecasting systems.

Realistic Limitations of Python-Based Demand Forecasting Model Development

Difficulties in Securing and Retaining Specialized Development Personnel

Realistic Limitations of Python-Based Demand Forecasting Model Development

The talent pool of data scientists, machine learning engineers, and MLOps specialists required for AI development is extremely limited in the market. For a domestic mid-sized company to recruit one skilled data scientist requires costs exceeding 100 million won annually, and retaining such talent long-term is an even more challenging task.

In startup stages, limited resources should be focused on building core business capabilities, but recruiting AI specialists creates significant financial burden. To solve these problems, some companies employ strategies of collaborating with external consultants or utilizing talent on short-term project bases, but these also show limitations in terms of knowledge transfer and project continuity.

According to research by global consulting firm McKinsey, 67% of domestic mid-sized companies that started AI-related projects failed to meet planned schedules due to talent acquisition problems, and 42% experienced project suspensions due to key personnel turnover.

Overcoming Uncertainty in Development Period and Costs

The process of developing demand forecasting models with Python typically requires at least 6 months to over a year. This is because complex stages must be completed including data collection and cleansing, model development and training, testing and optimization, and system integration.

The problem is that development periods are frequently extended due to unexpected data quality issues or iterative work for model performance improvement during this process. This uncertainty acts as a significant risk factor for companies' business plans and investment recovery timing.

AI experts point out that such delays stem more from business process understanding and data quality issues rather than technical challenges. Particularly in mid-sized companies and above, unstructured data from legacy systems or data silo problems are identified as major causes of project delays.

Decision-makers must establish project management systems that separate development processes into clear milestones and strengthen verification processes at each stage to minimize these risks. Additionally, it's essential to organize data governance systems from enterprise-wide perspectives and pre-build data pipelines suitable for AI projects.

Specialized solutions like Deepflow can significantly shorten implementation periods through already optimized methodologies and proven frameworks, providing strategic advantages for companies that need to respond agilely to business environment changes.

Hidden Burdens of Continuous Maintenance and Performance Improvement

AI model development is not a one-time project but a continuous journey. Even after development completion, continuous management including model performance monitoring, periodic retraining, and hyperparameter tuning is necessary. Particularly, model performance can deteriorate over time due to data drift phenomena, making regular updates essential.

In reality, approximately 40% of annual development costs in maintenance expenses occur continuously beyond initial AI model development costs. These maintenance costs are often underestimated during initial investment review stages and can act as serious budget pressure if not reflected in long-term TCO (Total Cost of Ownership) calculations.

AI adoption and financial performance standards

AI experts point out that model performance degradation in operational environments is one of the biggest risk factors for corporate AI projects. Particularly in mid-sized companies and above, continuous model management can become more difficult due to imbalances between organizational data science capabilities and IT operational capabilities.

Decision-makers must establish operational systems and budget plans for continuous value creation rather than simple development completion for AI project success.

Specific measures include building MLOps systems, introducing automated monitoring systems, and organizing dedicated teams for model performance evaluation and retraining. Specialized solutions like Deepflow have the advantage that service providers handle most of these operational burdens, allowing companies to concentrate resources on core business activities. This can be an important consideration especially for organizations lacking AI operational experience.

Technical Challenges of Scalability and System Integration

Many companies face unexpected technical difficulties when expanding prediction models initially started in single departments or limited scopes to entire enterprises. Numerous challenges need resolution during expansion including smooth integration with existing IT infrastructure, connecting various data sources, securing real-time processing capabilities, and maintaining performance as users increase.

AI experts analyze that these scalability problems are more significantly affected by organizational data governance and IT architecture maturity rather than technical constraints. Particularly in mid-sized companies and above, major challenges include integration with legacy systems, minimizing latency for real-time decision support, and ensuring compatibility with enterprise-wide IT security policies.

Decision-makers need architecture design considering enterprise-wide applicability from initial design stages to solve these scalability problems. Effective strategies can include adopting microservice architecture, building API-based interfaces, and utilizing cloud-native technologies.

Specialized solutions like Deepflow already possess enterprise-grade scalability and integration capabilities, facilitating linkage with various internal systems and minimizing technical risks that may arise during expansion processes.

Gaps in Industry-Specific Knowledge and Domain Expertise

Even with technical capabilities to develop models with Python, deep domain knowledge in relevant fields is essential for building sophisticated prediction models reflecting industry-specific characteristics. Each industry including logistics, retail, manufacturing, and energy has unique variables, patterns, and constraints, and effectively reflecting these in models is a challenge beyond simple technical issues.

For example, in fashion retail, complex factors like trend changes, seasonal effects, and discount policies affect demand, requiring deep understanding of the industry to accurately model these factors. AI experts point out that lack of domain knowledge is a major reason why even technically excellent models fail to lead to actual business value creation.

Particularly in mid-sized companies and above, the limitations of standardized AI models become more clearly evident in complex environments combining industry-specific characteristics with unique business processes. Decision-makers must build close collaboration systems between business experts and data scientists and establish knowledge management systems that systematically document industry-specific specialized knowledge for reflection in model development to overcome these domain expertise gaps.
