Executives & Managers: Must-Read! A Complete Guide to System Development Using the 'Cooking' Analogy

What Exactly Is System Development?

When you hear the term "system development," do you imagine difficult programming or tinkering with machines? Actually, it is not so rigid. If we use the most familiar analogy for us, it is "organizing the kitchen and recipes to create an ideal course meal". It refers to the overall design including not just making the dish (app), but also sourcing ingredients (servers), cooking procedures (business flows), and serving (network).

In business settings, introducing this "system" automates tasks humans used to do manually or consolidates scattered information. For example, think of changing a sales ledger that was manually totaled every month into a mechanism that automatically calculates upon input. This reduces errors and allows you to focus on new sales activities during the freed-up time.

1. Unveiling the True Nature of System Development through a Cooking Analogy

The Difference Between Single Dishes and Full Course Meals

Think of software development as "making a single dish," and system development as "planning and running a full-course banquet." Just making an app alone won't work without servers, and history won't be saved without data storage locations. System development creates the "whole state until it can be eaten," including all of these.

[Before] Managing data in Excel. File locations become unknown when staff changes.
[After] Unified system on the cloud. Anyone can access latest data from anywhere.
In other words, it achieves "eliminating individual dependency and democratization of information." In cooking terms, it's like building a kitchen where anyone can produce the same taste with the same recipe.

2. Why System Development Now? The True Value of Efficiency

Resolving Labor Shortages and Human Errors

Modern business challenges are "labor shortages" and "human errors." Systems do not get tired, so they work accurately 24 hours a day, 365 days a year. For example, if order processing is automated, even if orders come in at night, shipping preparation will be complete by morning.

[Useful in These Situations] Spending one day every week issuing invoices; making 10 phone calls to check inventory.
[Implementation Effect] Invoice issuance takes 1 minute; inventory confirmation is done just by looking at the screen.
In other words, "an 80% reduction in working hours" can be expected. Freed-up time can be allocated to creative work only humans can do, such as customer support or new planning. This is the greatest benefit of system investment.

3. Main Types of Systems (Store, Delivery, Backstage)

Three Vessels Tailored to Purpose

Systems are broadly divided into three types. First is "Web Systems." Like a store viewed via browser, used for customer-facing services. Second is "Mobile Apps." Like delivery personnel with smartphones, utilizing location info and notifications. Third is "Core Systems." Like the backstage of a kitchen, supporting internal business such as accounting and inventory management.

[Specific Examples] EC site construction uses Web Systems. Employee attendance management uses Core Systems.
[How to Choose] If showing to customers, use Web; if for internal use, use Core; if on the go, use App.
In other words, selection depends on "who uses it and where." By combining these, coordination becomes possible, such as customers ordering via smartphone and inventory automatically decreasing internally.

4. Development Flow (From Order to Delivery)

Requirements Definition as the Menu

Development does not start immediately. First, "requirements definition" decides what to build. In cooking terms, this is the stage of deciding the menu and recipes. If this is vague, the result will be "not what was expected." Afterward, design, manufacturing, testing, and operation follow.

[Important Point] Convey "what you really want to do" during the initial hearing.
[Failure Example] "Make it look good" is not understood. Specify concretely like "want to complete orders in 3 clicks."r>In other words, "whether it can be verbalized" is the key to success. Proper communication in the first half of the process is the only way to prevent rework and budget overruns.

5. In-House vs. Outsourcing (Home Cooking vs. Catering)

Trade-off Between Cost and Speed

This is the choice between making it yourself (In-House) or asking a vendor (Outsourcing). In-house is like home cooking; material costs are low, but time and skills are required. Outsourcing is like catering; cost is higher, but quality and speed are guaranteed because professionals make it.

[Suitable for In-House] Frequent small modifications; engineers exist in-house.
[Suitable for Outsourcing] Large-scale new construction; specialized knowledge required.
In other words, decide based on "whether it relates to core competitiveness." Parts that become unique strengths of your own company are made in-house, while routine tasks are outsourced; hybrid types are increasing recently. Accurately estimating your company's resources is important.

6. Tips for Avoiding Failure (Communication)

Choosing a Collaborative Partner

The most common cause of failure in system development is "lack of communication." It is not enough to just build and finish; improvements must be made while operating. Therefore, whether they are easy to ask questions to is very important.

[Check Points] Do they explain without using jargon? Is there after-care?
[Secret to Success] Set up weekly regular meetings.
In other words, "whether you can run together" is important. By choosing partners who try to understand your business, not just technical skills, a truly useful system will be completed.

Frequently Asked Questions Q&A

Q1: How much budget is required?
A: Depending on scale, but small-scale is around 1 million yen, core systems around 10 million yen. We recommend starting small to verify effects first.
Q2: How long does it take to complete?
A: Simple ones take 1 month, complex ones take 6 months to 1 year. Rushing requirements definition leads to delays later, so proceeding according to plan is the fastest way.
Q3: What happens if it fails?
A: You end up with a system that isn't used. To prevent this, creating prototypes early and refining them while listening to field voices is effective.

Where to Start? Concrete First Steps

You don't need to search for vendors immediately. The first thing to do is create a "List of Internal Pain Points". Interview each department about "tedious daily tasks" and "information taking too long to search." These are candidates for systematization. Once the list is ready, prioritize them and start reviewing the ones likely to yield the highest effects. Just this prevents wasteful investment.

Glossary (Concise Explanation of 5-10 Important Terms)

1. Requirements Definition: The stage forming the blueprint to decide what to achieve with the system.
2. UI/UX: Ease of viewing (UI) and ease of use (UX). User experience.
3. Server: High-performance computer to run the system. Data storage location.
4. DB (Database): Electronic shelves organizing and storing information. Good at searching.
5. API: Connection standards linking different systems. Bridge role for coordination.
6. Cloud: Server environment used via the internet. Low maintenance costs.
7. Maintenance & Operations: Maintenance after system completion. Fault response and update work.
8. Waterfall: Traditional development method progressing steps sequentially. Poor at changes.
9. Agile: Method making small iterations repeatedly. Strong against changes.
10. PoC: Proof of Concept. Small-scale experiment to test if an idea is technically feasible.
