What is BCP | Basics of Business Continuity Planning

【Disclaimer】 This article is a summary created based on public guidelines and information from the Small and Medium Enterprise Agency, the Ministry of Economy, Trade and Industry, the Tokyo Chamber of Commerce and Industry, etc. For actual BCP development and operation, we recommend consulting with experts and relevant administrative authorities.
Official Name and Meaning of BCP
BCP: Business Continuity Plan
Japanese: Business Continuity Plan
Purpose: Plans and preparations to continue and quickly restore core business operations even when facing emergencies such as natural disasters, accidents, infectious diseases, or cyberattacks
Target: From large corporations to small businesses and sole proprietors, development is recommended regardless of size
Differences Between BCP and Similar Terms
We will clarify similar terms that are often confused by managers and practitioners.
BCP (Business Continuity Plan)
A plan and preparation to continue business even during emergencies
Includes normal-time preparations + emergency response + recovery phases
BCM (Business Continuity Management)
Comprehensive management activities including continuous improvement and operation of BCP
BCM is the 'mechanism for running a BCP (plan)'
BCM = BCP + Operation + Improvement is the relationship.
Disaster Prevention Plan
A plan specialized for natural disasters
Focuses on protecting human life
Included as a component of BCP
Business Continuity Enhancement Plan
A public system certified by the Small and Medium Enterprise Agency / Business Continuity Enhancement Plan Certification System (Official Small and Medium Enterprise Agency)
Receiving certification offers benefits such as tax incentives, subsidy points, and low-interest loans
→ Once a BCP is formulated, it is also possible to apply for certification as a Business Continuity Enhancement Plan is the flow.
Why BCP is necessary for small and medium-sized enterprises | Differences from large companies
There is an image that 'BCP is for large companies,' but I will organize the reasons why small and medium-sized enterprises are the ones that need BCP the most.
① Small and medium-sized enterprises are more prone to business collapse during emergencies
Large companies ensure redundancy through multiple locations, multiple business partners, and abundant funds, but small and medium-sized enterprises operate with one location, few business partners, and limited funds.
One major business partner is hit by a disaster → Possibility of losing more than half of sales
One location is hit by a disaster → All operations stop
One manager is absent for a long period → Decision-making stops
→ The essence is to compensate for the lack of redundancy with BCP planning and preparation.
② Increase in 'BCP requests' from business partners and financial institutions
In recent years, cases where BCP formulation is a condition for doing business with large companies are increasing.
Major companies in the automotive, electronics, and food industries → Supply chain BCP requirements
Financial institutions → BCP status is now an evaluation item in loan screening
Government bidding → Certification of Business Continuity Enhancement Plan is a point-adding factor
→ We are in an era where "the presence or absence of a BCP is directly linked to business opportunities, financing, and public contracts."
3. "Business continuity capability" in the recovery phase creates management differences
The recovery speed after an emergency determines subsequent business continuity.
With BCP: Major operations resume in 1-2 weeks → Business maintained
Without BCP: Suspension for over a month → Business termination/customer loss → Risk of bankruptcy
Following the Great East Japan Earthquake and the COVID-19 pandemic, companies with a BCP tended to have a higher business continuity rate after emergencies as pointed out by the Small and Medium Enterprise Agency and various research organizations.
4. Preparation for "what happens if something happens to me" for business owners
For SMEs, a BCP also functions as preparation for sudden illness, accidents, or death of the business owner in addition to disasters.
Clarifying decision-making authority in the absence of the owner
Establishing handovers for important documents, contract information, and passwords
Pre-designating successors or proxies
→ In the case of SMEs, "risks to the individual business owner" are also important elements that should be prepared for with a BCP.
5 Basic Components of a BCP

Explaining the basic structure necessary for BCP formulation, from risk analysis to recovery strategy.
A BCP for SMEs consists of the following 5 basic elements. If you organize these in order, a minimum viable BCP will be completed.
Basic 1: Risk Analysis | Anticipating what might happen
List the risks your company may face and probability of occurrence × degree of impact to prioritize them.
Major Risks
Natural Disasters: Earthquakes, floods, typhoons, heavy snow
Accidents/Failures: Fires, power outages, communication failures, IT failures
Infectious Diseases: Pandemics, mass infections
Cyber Attacks: Ransomware, data leaks, unauthorized access
Human Risks: Sudden illness, resignation, or accidents involving management or key personnel
Business Partner Risks: Bankruptcy or disaster damage to major business partners
Economic Risks: Rising raw material costs, exchange rate fluctuations
How to prioritize:
High impact × High probability → Highest priority measures
High impact × Low probability → Secondary priority measures (prepare with insurance, contracts, etc.)
Low impact × High probability → Absorb through normal operations
Low impact × Low probability → Postpone
Basic ② Identification of Core Business | Deciding "tasks that must never be stopped"
In an emergency, decide in advance what to prioritize with limited resources.
3 questions to identify core business
What percentage of sales does this operation generate?: Which operations generate the top 80%?
Is it an operation that supports the trust of business partners and customers?: The magnitude of trust lost if stopped
Is it an operation with a legal or contractual obligation to continue?: Medical, infrastructure, public contracts, etc.
→ Use these questions to narrow it down to about 3 core businesses. You can then make the decision to systematically scale down or stop the rest during an emergency.
Basic 3: Preparation of Countermeasures | Concrete Preparations for Business Continuity
Prepare the physical and organizational preparations necessary to continue core business operations.
Physical preparations
Power: UPS, portable power supplies, emergency generators
Communication: Multiple lines, mobile Wi-Fi, satellite communication
Data: Backups (cloud, NAS), redundancy
Business continuity infrastructure: NAS, servers, business systems
Alternative office space: Remote work, satellite offices
Stockpiling materials: Raw materials, parts, water, food
Organizational preparations
Emergency contact network
Rules for delegating decision-making authority
Safety confirmation system
Notification procedures for business partners
Basic 4: Establishing a Structure | Deciding Who Does What
Determine the command structure and role assignments for emergencies during normal times.
Composition of the Disaster Response Headquarters: Head, Deputy Head, and functional leads
Order of succession: Order of decision-making authority in the absence of the Head
Communication network: Contact routes for employees, business partners, government, and financial institutions
Role manual: List of tasks for each person in charge
Basic 5: Training and Improvement | Keeping the Plan 'Ready to Use'
A BCP only functions if it is regularly trained and improved, rather than just created and forgotten.
Regular training: Tabletop and practical exercises 1-2 times a year
Review: Annual review based on personnel changes and business environment shifts
Education: Thorough awareness for new employees and executives
Continuous improvement: Post-training review and plan revision
How to Develop a BCP for SMEs | 5 Practical Steps
We will organize the order in which SME owners and managers should start.
Step 1: Risk Assessment of Your Company
SME Agency's BCP Formulation and Operation Guidelines, referring to public guidelines, summarize the risks that could occur based on your industry, size, and location on a single sheet of A4 paper.
Step 2: Identification of Core Businesses
Narrow down the 'tasks that must never stop' to no more than three. Sharing this within the company will speed up priority decision-making during emergencies.
Step 3: Development of Basic Measures
Establish minimum preparations based on the four pillars of power, communications, data, and personnel to support core business operations. Specific measures are organized in detail in [BCP Measures for SMEs: 5 Business Infrastructures to Keep Operations Running].
Step 4: Establishing Systems and Communication Networks
Establish command chains, delegation rules, and communication networks for emergencies and share them with employees and relevant parties.
Step 5: Training and Improvement
Conduct training 1-2 times a year and improve the plan through reviews. A "non-functional BCP" is meaningless, so develop it into a "usable BCP" through training.

Common Patterns of Failure in BCP Formulation for SMEs

A wake-up call and countermeasures to prevent the creation of ineffective plans or plans that become mere formalities, and to build a truly functional business continuity plan.
Failure Pattern 1: Aiming for a 'Perfect BCP'
Rather than getting discouraged by aiming for a 100-page BCP, it is far more effective to start with a practical BCP of about 10 A4 pages.
Failure Pattern 2: Copying Templates Directly
Templates from the Small and Medium Enterprise Agency and Chambers of Commerce are convenient, but copying them without reflecting your company's industry, scale, and risks will not work in an emergency.
Failure Pattern 3: 'Create and Forget'
20% of a BCP's value is realized at the time of creation, and the remaining 80% is realized through training and improvement. Please be sure to plan for training 1-2 times a year.
Failure Pattern 4: No Scenario for the Absence of Management
The biggest risk for SMEs is the sudden illness or accident of the business owner. Please be sure to include decision-making authority in the absence of management in your plan.
Failure Pattern 5: Ignoring Digital and Cyber Risks
In recent years, ransomware and data leaks have been hitting SMEs directly. Please be sure to include cyber measures in addition to physical preparations.
Frequently Asked Questions (FAQ)
Q1. Is BCP mandatory by law?
A. There is no legal obligation for general companies. However, it is recommended or mandatory for specific industries such as medical, nursing care, infrastructure, and finance. Additionally, cases where BCP formulation is requested by major business partners are increasing.
Q2. What is the difference between BCP and BCM?
A. BCP = 'Plan/Preparation', BCM = 'Management activities including continuous operation and improvement of BCP'. BCM is a comprehensive concept that encompasses BCP.
Q3. Is BCP necessary for sole proprietors?
A. Yes, it is. In fact, for sole proprietors operating alone, preparing for 'when something happens to me' is the key to business continuity. A simplified version of a BCP is sufficient.
Q4. How much does it cost to develop a BCP?
A. If you create it in-house, the cost is almost zero. If you hire an external consultant, it can range from 300,000 yen to several million yen depending on the scale. Using the public formats provided by the Small and Medium Enterprise Agency makes in-house creation a realistic option.
Q5. Where should I start?
A. Start with the 3 steps of Risk Assessment → Identifying Core Business → Preparing Countermeasures. Specific countermeasures are detailed in [BCP Measures for SMEs | 5 Business Infrastructures to Keep Operations Running].
Q6. How often should the BCP be reviewed?
A. An annual periodic review + improvements after drills is the standard. Reviews are also necessary whenever there are major changes such as shifts in the business environment, personnel changes, or new business transactions.
Q7. What is the relationship with the Business Continuity Enhancement Plan certification?
A. Once you develop a BCP, you can apply for certification as a "Business Continuity Enhancement Plan." Obtaining this certification provides public benefits such as tax incentives, low-interest loans, and additional points for subsidies.
Q8. What should I prepare for disaster stockpiles?
A. Power (portable power stations), communication (satellite devices), information (emergency radios), water (water purifiers), and food (emergency rations) are the 5 pillars, with a minimum of 3 days' supply as a guideline. Details are organized in the Serious Preparation Magazine.
Q9. How should I prepare for business data backups?
A. Redundancy using Cloud + Business NAS is the basic approach. Business NAS for SMEs is explained in detail in articles such as QNAP TS-464 and Synology DS224+.
Q10. What kind of BCP drills should I conduct?
A. Combine two types: "Tabletop exercises" (scenario-based discussions) and "Practical drills" (practicing the actual activation of the BCP). It is realistic to start with one tabletop exercise per year.
Summary | The correct approach for SME BCP is "simple and practical"
BCP is a plan and preparation for SMEs to continue operations without stopping even in emergencies. Rather than aiming for a perfect 100-page BCP, an approach of creating a simple and practical BCP of about 10 A4 pages and growing it into a "living BCP" through 1-2 drills per year is more suited to the reality of SMEs.
