Costs depend on scale and requirements. This article discusses PoC-led development, including cases starting around JPY 1.8 million, and a flexible GCP-based approach to validation and implementation.
System development budgets: a practical look at PoCs and Google Cloud
One of the first questions about system development is cost. For our projects,around JPY 1.8 million is one initial reference point. This refers to an initial phase, particularly a PoC. Production development costs vary significantly with scale.
This article discusses development budgets through the lens of PoCs and Google Cloud.
Why around JPY 1.8 million can be a reference point
System development includes more than coding:
- Discovery and requirements
- Technology selection and architecture
- UI/UX design
- Backend development
- Testing and validation
Clarifying what to build is particularly important early on. Insufficient investment in this stage can cause rework later.
For an illustrative team of one project manager and one or two engineers working for several weeks to a month,approximately JPY 1.5–2 millioncan be a budget reference. The article uses around JPY 1.8 million as an initial investment guide balancing scope, quality and speed.
Why begin with a proof of concept?
Starting immediately with a large development project carries risk, sobeginning with a PoC is a common approach.
A PoC investigates:
- Technical feasibility
- Business viability
- Suitability for actual operations
In AI, video generation and analytics, proceeding without evaluation can reveal unexpected accuracy or processing-cost problems later.
Therefore,investing around JPY 1.8 million in an initial PoC before deciding the production scopeis one approach discussed here.
How to think about Google Cloud costs
Google Cloud is used in many system development projects. Potential benefits include:
Start with a small scope
Usage-based resources can support a limited initial environment, particularly during a PoC.
Plan for scaling
Infrastructure can expand with users and data, reducing the need to rebuild later.
Connections to analytics platforms
Integration with BigQuery and Bigtable can incorporate data use into the wider design.
Google Cloud cost considerations
With usage-based billing, account for:
- API charges for AI, speech, image generation and other services
- Server runtime
- Storage
Some small PoC environments may cost thousands to tens of thousands of yen monthly, while production costs vary substantially with design. This makescost planning during development important.
Illustrative budgets by phase
The article presents the following phase-based guide.
Phase 1: PoC and requirements
- Duration: two weeks to one month
- Budget: approximately JPY 1.5–2 million
Phase 2: Production development
- Duration: one to three months
- Budget: approximately JPY 3–8 million
Phase 3: Operations and improvement
- Monthly: tens to hundreds of thousands of yen
Choosing an approach
Consider these steps to manage development risk:
- Avoid starting with a large, undefined scope
- Validate with a PoC
- Start with a focused Google Cloud environment
- Design for later expansion
