Relationship between DX and consulting

What is DX

The definition of DX (Digital Transformation) proposed in 2004 by Professor Eric Stolterman of Umea University in Sweden is as follows.

“It is a technology that continues to evolve and has some impact on human life, and as a result, people’s lives change for the better.”

The Ministry of Economy, Trade and Industry of Japan summarized the following definitions in the ” Guidelines for Promoting Digital Transformation (Promotion Guidelines) ” issued in 2018.

“Companies respond to drastic changes in the business environment, utilize data and digital technology, and transform their products, services, and business models based on the needs of customers and society. To transform our culture and climate and establish a competitive advantage.”

Many of the DX that are currently in the news are mainly DX from a business perspective as defined by the Ministry of Economy, Trade and Industry.

In recent years, it has become important for companies to quickly identify changes in the external and internal environment and create new value by using the power of digital technology to guide them to optimal management strategies.

According to a report released by the Ministry of Economy, Trade and Industry, “If DX conversion cannot be realized, economic losses of up to 12 trillion yen will occur annually after 2025.” It is possible to boost the real GDP to more than 130 trillion yen in 2018.”

That is why the promotion of DX is essential in Japan today.

What is consulting

Consulting refers to the work of presenting solutions to executives (especially managers) of companies (rarely public institutions such as governments) and helping them develop.

In other words, we provide professional consulting (consultation, guidance, planning, and planning) in order to solve corporate issues such as management, strategy, accounting, organization, human resources, and IT.

Business companies that provide consulting services are called “consulting firms,” and people who provide consulting services are called “consultants.”

The consulting industry can be broadly divided into six types, and the services provided by each company differ.

strategy consulting

Strategy Consulting is a firm that mainly provides consulting in strategic areas.

We are in charge of planning and executing plans to discover and solve management issues of requested companies, and support global expansion.

It is characterized by promoting large-scale project-type consulting with a small number of elites.

Recently, some companies have built bionic companies (new-age organizations where humans and technology merge) to advance their digital strategy approach.

Representative company

  • McKinsey & Company
  • Boston Consulting Group
  • Bain & Company

Comprehensive business consulting

Comprehensive business consulting is a firm that advocates comprehensive consulting.

In addition to providing management strategy services, we also offer a wide range of consulting services, including personnel strategy, M&A, legal affairs, system introduction centered on IT, FAS (Financial Advisory Service), and specific industry-specific consulting.

The company scale is large, and it supports a wide range of industries and themes. Our clients are often large companies, and a single project requires a large budget and manpower.

  • Deloitte Tohmatsu Consulting
  • PwC Consulting
  • Accenture
  • IBM Japan

IT consulting

IT consulting is a firm that provides solutions related to customers’ business and management from the perspective of IT. From IT strategy, ERP , CRM, SCM introduction to construction and maintenance of information processing system, we are responsible for all IT in corporate management.

IT consulting firms are companies that use IT as a means to solve customer problems, rather than for the purpose of introducing systems using IT. Now that DX is accelerating, IT knowledge is being emphasized even in strategy formulation, and the demand for IT consulting is increasing.

  • ABeam Consulting
  • Hitachi Consulting

Domestic think tank consulting

Domestic think tank consulting is a firm with major securities companies and financial institutions as parent companies.

It is characterized by consulting that utilizes the know-how of major corporate groups, and covers a wide range of fields from strategy planning to system construction.

  • Mitsubishi UFJ Research & Consulting
  • Fujitsu Research Institute

HR/Human Resource Development Consulting

Human resources and human resource development consulting is a firm that specializes in solving problems related to people and organizations, such as organization, personnel, recruitment, education, and training.

In addition to consulting for human resources and organizations associated with the execution of strategies, we are also involved in the personnel system itself.

Recently, in order to strengthen competitiveness and improve productivity through the use of digital technology, we have been reforming our corporate culture and awareness toward DX, as well as developing human resources.

The role of consulting in DX

DX that does not align with business goals often ends in failure. Therefore, in such cases, the advice of a DX consultant is required.

What role does DX consulting play in promoting it?

DX Consulting has the role of “taking quick action from insight into DX, and responding from the conception of ideas to the construction of a business”.

Business and social uncertainty demands leadership and ingenuity more than ever before. The best way to keep business running is for companies to respond quickly to change and make strategic business decisions based on reliable information.

But most companies can’t do it on their own. That’s why you need DX consulting.

DX Consulting helps companies through the following processes.

① Vision formulation

We extract the gap between the company’s current issues and future ideals, and formulate a vision, such as “how the company and business departments face digital, and what kind of direction digital should achieve.”

(2) Idea creation

We understand the client’s business and create and propose unprecedented products, services, and business models.

(3) Use case creation

When defining system requirements, visualize the situation from the point of view of the user who uses the system.

④PoC/Pilot (MVP)

We determine the feasibility of new ideas and concepts and verify their effectiveness.

⑤ Support for full-scale development

We provide end-to-end support from system development to installation and maintenance.

⑥Organization and culture change

We reorganize organizations and processes to bring productivity improvements and cost reductions to existing businesses. We will review the current work itself and change the way we work.

⑦ Human resource development

In order to acquire digital human resources, we will develop internal systems and skill definitions, etc., and improve the organization so that they can be firmly established even after joining the company.

Advantages of receiving DX consulting

Organizing, visualizing and objectifying information

Internal and industry facts are usually shared. However, even if it is a known fact, in most cases, “information is not organized and given meaning”.

Just by organizing the information and making it easy to see, the problem becomes clear.

It is not easy to organize and give meaning to “information” in a meaningful way, but consultants are experts who use logical thinking and frameworks, so they are good at visualizing and objectifying information.

If information related to DX is organized, internal discussions will be objective and active, and the accuracy of decision-making for DX promotion will increase.

Ability to incorporate diverse know-how and skills

It is possible to incorporate various know-how and skills such as the latest successful cases and overseas projects from consultants who have been involved with numerous companies and have accumulated achievements.

Innovative and effective ideas are important in promoting DX. You can strengthen your company’s competitiveness by broadening your business horizons from advice from consultants and positively streamlining existing businesses.

Opinion as an expert

Our consultants have deep knowledge in various fields such as marketing, financial accounting, industry, IT, and human resources.

For a company, it is better to have a consultant enter and proceed with the part of the company that you want to reform while receiving professional advice, rather than gathering people without specialized knowledge to build from scratch, because it will solve problems and reform. You can shorten the time of trial and error.

In particular, consultants who specialize in a certain field will be helpful because they have a wide and deep drawer on the issues.

Problems when receiving DX consulting

Tends to be entrusted to external parties

One of the most common reasons for failure is to ask a consultant to handle your company’s issues that only the person in charge can see.

Coordination between departments within the company and coordination with business partners also occur, so it is necessary to have close dialogue with the consultant and constantly check the progress.

It’s a mistake to take everything a consultant says with a grain of salt

Even if it can be operated under the guidance and cooperation of a consultant, if it is operated only in-house, it will be unreasonable, and the improvement plan will fall into a state of “rice cake in the picture”, and the improvement may be delayed.

When receiving consulting, it is also important to be able to receive advice that matches the level of your company.

Can be expensive

The cost of DX consulting depends on the size of the company, but the market price is several million to tens of millions. Even if you anticipate a certain amount of cost at the time of the request, if the problem is deep-rooted during the consulting process, it may take time to analyze and create a solution, and additional costs may be incurred.

What industries and companies should receive DX consulting?

In-house digital talent shortage

Since IT operations have been dependent on external vendors, companies that do not have human resources with deep knowledge of the digital field who can promote DX need the cooperation of consultants with high IT expertise.

Existing business is facing difficulties

Companies that do not actively incorporate IT and are facing difficulties in their existing businesses should receive consulting. Also, even if existing businesses are doing well, simply maintaining them will result in a loss of competitive advantage in the future.

For companies that want to “add additional value to their existing business and tie it to future business development,” but do not know the specific method and their internal activities are not moving in the direction of reform, consulting need advice.

system cannot be implemented

Once ideas and business models for reform are formulated, it is the system that embodies them.

However, it is quite difficult to build a zero-to-one system in-house, and because it is often deployed on a cloud basis, it may not be possible to respond with conventional legacy knowledge and development methods.

We need consultants who can provide solutions for system design and implementation.

How to choose a DX consulting company

When choosing a DX consulting company

  • area of ​​expertise
  • where there is a track record
  • budget

Let’s focus on the above three points.

area of ​​expertise

Each DX consulting company has its own specialty.

The three main areas are:

  • Strategic consulting area
  • System development area
  • DX conversion of services and products

It is important to ask a DX consulting company that has an area of ​​expertise that meets your needs.

Of the three areas above, it is said that the strategic consulting area can meet the widest range of needs, so it is recommended to choose a company that has this specialty area when the direction of DX conversion is not decided.

If you can design in-house but do not have the resources to develop a system, it is a good idea to ask a DX consulting company that is good at system development.

If you have your own product and want to promote its conversion to DX, we recommend a DX consulting company that specializes in service and product areas.

where there is a track record

We will look at the performance of the DX consulting company and judge whether it is likely to answer our company’s needs and make a request. Let’s check the details and results of the actual implementation of consulting on the website of the DX consulting company.

Even if your company’s needs and areas of expertise match, if the track record is poor, there may be differences in recognition of details, resulting in a mismatch. If you check the results and match your company’s needs, you can expect highly accurate consulting.


The cost of receiving DX consulting varies greatly depending on the content of the measures and the scale of implementation. The market price is about several million to tens of millions of yen, but if it involves large-scale system development, it may cost hundreds of millions of yen. Also, the larger the DX consulting company, the higher the cost.

There are many cases where the budget is not listed on the homepage, so let’s check the cost by inquiring individually by e-mail form etc.

4 companies that provide DX consulting

Now, let me introduce four companies that actually do DX consulting.

Construction of Bic Camera information infrastructure

Bic Camera Co., Ltd., a major consumer electronics mass retailer, operates an integrated information platform that is used by about 9,000 people from the group’s field sites to the management department, but the processing load has increased as the amount of data and users have increased in recent years. was slowing performance and hampering analytics and reporting activities.
