挑战
制造商主要依靠现场专家知识进行根本原因分析。当有缺陷的产品被送到实验室进行分析时，这很费力，而且总是在进行验尸。从 IT 和 OT 收集数据的制造商也需要对各种专业人士有全面的了解才能理解它。这不仅耗时，而且效率低下。
解决方案
鉴于工业 4.0 革命，根本原因分析正在得到改进。曾经的验尸分析已成为预测分析。机器学习算法和大数据分析的进步有助于使用自动化方法执行根本原因分析。这些方法基于生产车间的历史实时数据。对于万无一失的技术，算法也接受制造商提供的输入。这是至关重要的，因为传统或机构知识也被考虑在内，并且预测的准确性在下一次得到提高。
数据驱动的诊断模型经过训练以检测任何与正常情况的偏差，以将其声明为异常。机器学习算法捕捉 5Ms 制造对输出质量的影响。算法将临界值添加到每个已识别的原因并相应地生成信号。

IoT Data Analytics Case Study - Packaging Films Manufacturer
The company manufactures packaging films on made to order or configure to order basis. Every order has a different set of requirements from the product characteristics perspective and hence requires machine’s settings to be adjusted accordingly. If the film quality does not meet the required standards, the degraded quality impacts customer delivery causes customer dissatisfaction and results in lower margins. The biggest challenge was to identify the real root cause and devise a remedy for that.

Reducing Scrap and Increasing Efficiency in Brick Production
Quality management in this facility was only done at the end of the production process. This makes it hard to link scrap output to its root causes and understand when and why faulty bricks are being produced. This makes the process not only unpredictable but also inefficient.

CleanTelligent Enhances Janitorial Software Solutions with Infor Birst
CleanTelligent Software, a company that aids in-house and contracted janitorial teams in streamlining communication and improving quality control, faced a significant challenge. Their clients were demanding a more dynamic way to present reporting data. The company's software was primarily used to analyze and summarize a custodial team's performance, replacing a highly manual, paper-driven process. However, the initial differences between service providers in the janitorial industry are often unclear, and the cost of switching is comparatively low. This situation led to high client turnover, with a janitorial company's customer lifetime averaging four years or less. CleanTelligent needed to improve the customer experience with dynamic dashboards and reporting, retain customers through predictive analysis, capitalize on advanced analytics capabilities to build market differentiation, and improve client retention rates.
