The increase in "tasks that only the person in charge understands" is often caused by a common failure pattern: operational improvements that depend on individuals. The challenge arises when skilled individuals are relied upon too heavily, resulting in no lasting systems. When dependence on individual skills and experiences continues, it becomes "the norm" and is no longer recognized as a problem. It is important to not only improve individual tasks but also to re-evaluate business processes, data, and systems as a whole, designing a structure where "anyone can execute tasks with the same quality." 【Do you face any of these challenges?】 ■ Business operations come to a halt when a specific person is absent ■ Business procedures are not documented ■ Handover takes a long time or is not possible ■ Methods differ from one person in charge to another ■ There is an atmosphere that makes it difficult for others to get involved in the tasks ■ Business improvements are stagnant, and the status quo continues *For more details, please download the PDF or feel free to contact us.

One common failure pattern in "tasks only understood by the person in charge" is superficial standardization. While there may be documents, they often diverge from reality, resulting in a situation where they are ultimately not used on-site. This is rooted in a lack of a culture of standardizing operations. A shift from "relying on people" to "entrusting to systems" is necessary. It is key to not only develop manuals but also to translate them into forms that are actually used in the field. 【Do you face any of these challenges?】 ■ Operations come to a halt when a specific person is absent ■ Work procedures are not documented ■ Handover takes a long time or is not possible ■ Methods differ from person to person ■ There is an atmosphere that makes it difficult for others to get involved in the tasks ■ Business improvements are not progressing, and the status quo continues *For more details, please download the PDF or feel free to contact us.

One common failure pattern in "tasks only understood by the person in charge" is the procrastination of manual creation. Even if the importance is understood, it is not initiated, and the personalization of the task progresses further. Since the procedures exist only in the mind of the person in charge, issues such as difficulties in handover gradually become apparent. Let's start by identifying the tasks that have become personalized and clarifying "why this person is the only one who can do it." 【Do you have any of the following issues?】 ■ Business stops when a specific person is absent ■ Business procedures are not documented ■ Handover takes time or is impossible ■ Each person has a different way of doing things ■ There is an atmosphere that makes it difficult for others to get involved in the tasks ■ Business improvement is not progressing, and the status quo continues *For more details, please download the PDF or feel free to contact us.

One of the common failure patterns in business systems is the absence and obsolescence of documentation. There is a disconnect between the actual situation and the specifications, leading to a state where it cannot be accurately understood. As a result, a "system that cannot be changed" is created, making improvement itself a risk. It is essential to review and rebuild the information infrastructure itself, rather than making ad-hoc improvements. A shift to a design that assumes changes is required. 【Do you face any of these issues?】 ■ Bugs and troubles occur every time there is a specification change ■ The number of people who understand the system's structure is limited ■ It is difficult to predict the impact range, leading to delays in change decisions ■ Even small improvements require significant effort ■ There is a dependency on external vendors for every modification ■ There are business systems that are said to "break when touched" *For more details, please download the PDF or feel free to contact us.

One common failure pattern in business systems is maintenance that has become overly dependent on specific individuals. Only certain personnel can understand it, leading to a black box situation. This is one of the structural factors that accumulates "difficulty in making changes." By establishing a structure where business, data, and systems are integrated, we can finally realize a "system that is resilient to changes." 【Do you face any of these challenges?】 ■ Bugs and issues arise with every specification change ■ The number of people who understand the system's structure is limited ■ It is difficult to predict the scope of impact, making change decisions time-consuming ■ Even small improvements require significant effort ■ There is a dependency on external vendors for every modification ■ There are business systems that are said to "break when touched" *For more details, please download the PDF or feel free to contact us.

One common failure pattern in business systems is the accumulation of individual modifications. As a result of prioritizing certain responses, the overall consistency breaks down and becomes complicated. The cause lies not in "technology," but in the "accumulation of design and operation." First, it is essential to clarify "why it is difficult to make changes" and gradually transition to a system that is resilient to change, which will be the first step toward sustainable business improvement. 【Do you have any of the following issues?】 ■ Bugs and troubles occur every time there is a specification change ■ There are only a limited number of people who understand the system's structure ■ It is difficult to predict the scope of impact, leading to delays in change decisions ■ Even small improvements require significant effort ■ There is a dependency on external vendors for every modification ■ There are business systems that are said to "break when touched" *For more details, please download the PDF or feel free to contact us.

A common failure pattern when introducing tools is that while individual tasks may improve, the overall process becomes more complicated. The cause is not an "Excel problem," but rather an "operational problem." Decisions to create things in Excel because it is convenient accumulate, leading to a structure where Excel proliferates continuously. Improvements to individual tools or partial system implementations are insufficient. By redesigning business processes, data, and systems as a whole, we can finally achieve a structure that is "resilient to change" and "not dependent on specific individuals." 【Do you have any of these issues?】 ■ Multiple similar files exist, and the latest version is unclear ■ Only specific personnel can perform update tasks ■ Data aggregation and transcription take a lot of time ■ Input errors and formula breakdowns occur frequently ■ Storage locations and naming conventions are inconsistent ■ Business operations come to a halt when the responsible person is absent *For more details, please download the PDF or feel free to contact us.

One common failure pattern in companies where Excel continues to proliferate is neglecting to address individualization. This leads to a structure that only the creator understands, making handovers and improvements difficult. Issues such as individualization and black-boxing have become chronic in many companies. It is important not just to continue using Excel, but to review the entire business process and transition to an appropriate system. 【Do you face any of these challenges?】 ■ There are multiple similar files, and it is unclear which is the latest version ■ Only specific personnel can perform update tasks ■ It takes a long time to aggregate and transcribe data ■ Input errors and formula breakdowns occur frequently ■ Storage locations and naming conventions are inconsistent ■ Business operations come to a halt when the responsible person is absent *For more details, please download the PDF or feel free to contact us.

One common failure pattern in companies where Excel continues to grow is the ongoing expansion without establishing rules. By continuously adding to files, they become numerous and uncontrollable. While Excel is convenient and easy to use, continuing to use it without management rules can easily become a bottleneck in operations. The first step is to organize the current situation and visualize "where the waste and risks are." 【Do you have any of the following issues?】 ■ Multiple similar files exist, and the latest version is unclear ■ Only specific personnel can perform update tasks ■ Data aggregation and transcription take a long time ■ Input errors and formula breakdowns occur frequently ■ Storage locations and naming rules are inconsistent ■ Operations come to a halt when the responsible person is absent *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we consistently supported a food company's core system renewal, utilizing a data model from ERP implementation to data migration. The company required business management that took into account the complex commercial flows unique to the food industry. Since various campaign prices and special pricing significantly impact profits, there was a need for a system that could accurately grasp profit and loss by customer and item, and quickly reflect this in estimates and sales strategies. To address this, we created a data model of the current business operations, visualizing and analyzing the business characteristics and challenges. By designing the improved state as a data model and reflecting it in the RFP, we clarified the requirements and enabled the selection of an appropriate ERP package. Additionally, we improved migration quality and efficiency through data mapping. 【Results and Effects】 - Improved accuracy of vendor proposals and estimate amounts through enhanced RFP precision - Reduced add-on and customization costs with To-Be model and low-code approach - Reduced labor and costs for data migration by utilizing the As-Is model - Enhanced overall project quality and success probability through the visualization of business requirements *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we rebuilt the insurance contract management system for a property and casualty insurance company and established a framework that allows for the integrated management of multiple products. The company required support for a wide variety of forms and a vast number of management items, as well as the ability to address complex and advanced business requirements. Since individual systems were built for each insurance product, modifications to multiple systems occurred every time there were regulatory or legal changes, resulting in significant development and maintenance costs. To address this, we defined insurance products as a common model and systematized business rules and administrative constraints within a data model. We designed a database that could manage multiple insurance products within a single system and significantly improved development productivity and maintainability by linking model information to low-code tools. [Results and Effects] - Significantly reduced lead time for market introduction of new products - Reduced system maintenance and operational costs - Achieved rapid and efficient responses to regulatory and legal changes - Facilitated easy addition of products and expansion of functions through a common platform *For more details, please download the PDF or feel free to contact us.

At ITS, by adopting a unique data modeling approach, we solve the challenges inherent in legacy systems while inheriting their benefits and achieving a reconstruction that incorporates new business requirements. Methods for reconstructing legacy systems include rehosting (refreshing only the infrastructure), rewriting (replacing development languages and tools), straight conversion (recompiling in a new language), and rebuilding (reconstructing from scratch). However, we believe these methods are insufficient as means to address the challenges inherent in legacy systems. **Benefits of Model Creation** - Untangles complex information and provides a stable data structure - Inherits strengths from the current system while adapting to new business requirements - Eliminates individual dependency through standardized model creation techniques - The logical model serves as a consistent common blueprint from system construction to maintenance *For more details, please download the PDF or feel free to contact us.*
