System development that contributes to business

What we do?

Sourcemaker specializes in source code creation tailored to our client's business needs. We expand the process typically handled by a general software vendor/IT Consultant to include not only the development phase but also planning and system operation phases.

Service Introduction

Our Services

Business & Product Strategy

Business & Product Strategy

We organize business and operational context, creating "structures" and "maps" for decision-making. We connect competitors, value, operations, and metrics to materialize them into actionable development plans. Generative AI is integrated as an aid to accelerate issue organization and comparative analysis.

  • Positioning analysis with competitive differentiation
  • Value chain visualization to identify bottlenecks
  • Business/system structuring: operations → systems → data → responsibilities
  • Issue structuring (tree/hypothesis organization)
  • KPI planning / KPI tree development (definitions, calculations, accountability)
  • (AI utilization) Brainstorming templates, draft materials, comparison tables, etc.

Deliverable Examples

Positioning analysis (competitive comparison/differentiation/decision materials)Value chain / business-system map (workflow, feature placement, responsibility breakdown)KPI definition documentKPI tree (formulas, measurement methods, accountability)Issue treeHypothesis listDraft roadmapRequirements scope proposal
UX / UI Design

UX / UI Design

We design experiences that are intuitive and easy to use, validated through user context understanding. From information architecture to UI design, we create cohesive deliverables that connect to development (rules and components). Generative AI is used for prototyping and increasing iteration cycles.

  • User research design and executionRecruiting design / Interview design / Insight organization
  • Experience design & Information Architecture (IA)Customer journey / User flow / Wireframe
  • UI design connecting to implementationDesign system creation / Key screen & state design / Component design
  • (AI utilization) Prototyping with Figma Make, copy suggestions, UI variations, etc.

Deliverable Examples

Research plan (target criteria/screener/questionnaire/field plan)Insight organization (implications, hypotheses, priorities)Customer journeyUser flowWireframeUI design (key screens, state design, error/empty states)Design system (design tokens, components, operational rules)Prototype (for validation)Usability test results memo
Development

Development (Web / App / Backend)

We move products forward with architecture designed for continuous change and implementation built with operations in mind. To balance quality and speed, we assume testing and automation, and accelerate implementation, review, and documentation with AI-driven development.

  • Integrated Web / App / Backend development (including API)
  • Enhancement planning from service KPIs → specification → estimation
  • Test design (viewpoints, cases, acceptance criteria)
  • Continuous E2E implementation for quality improvement (regression prevention, release stabilization)
  • AI-driven development (A2A / Cursor / Devin for implementation, review, documentation)

Deliverable Examples

Specifications (user stories/acceptance criteria)EstimatesImplementation planImplementation (Web/App/Backend, API, infrastructure configuration)Test viewpoint table / test cases, E2E test suite (continuous execution)Review records (design/implementation)Operational documentation (procedures/architecture diagrams)AI-driven development operational rules (review procedures, handling of generated content, guardrails)
Operations & Maintenance

Operations & Maintenance (Minimum Flat Rate)

We provide monitoring, updates, and security necessary for stable operation within a defined scope at minimum cost. By running defensive operations "just right," we create a foundation for continuous improvement. Generative AI is integrated for operational knowledge inquiries and inspection assistance.

  • Monitoring operations with Datadog (visualization & metrics)
  • Error monitoring & alert operations with Sentry
  • Dependency update detection & operations with Dependabot
  • Standardization of entry-point measures such as WAF deployment
  • Enhanced traceability through audit log implementation
  • (AI utilization) Inquiry response for system questions (knowledge search & answers), etc.

Growth Support

Growth Support (Continuous Improvement & Development)

We handle continuous development aimed at KPI improvement. We cycle through observation → hypothesis → measure → implementation → verification, accumulating learnings. We separate purpose and contract design from operations & maintenance, flexibly designing effort and team structure based on measure content.

  • KPI observation with GA (including event/conversion design)
  • Analysis & dashboard development with Metabase
  • Behavioral analysis with Clarity (identifying friction points)
  • Continuous agile development through backlog management (priority & release planning)
  • Continuous monitoring & improvement of performance/SEO with Lighthouse
  • (AI utilization) Insight extraction, measure proposals, implementation cycle acceleration, etc.

Insourcing & Team Development

Insourcing & Team Development (Client Team Modernization)

Client engineers join our development team to learn development processes through real projects. From requirements understanding to design, estimation, and review, we establish the judgment needed in the field through "patterns" and "operations." We combine AI review and human review to reduce dependency on individuals.

  • Client engineer team participation (pair/mob & review co-attendance)
  • Requirements understanding & breakdown patterns (issues, assumptions, scope, acceptance criteria)
  • Participation in architecture review (responsibility division, data/permissions, extensibility)
  • Realistic estimation with QCD awareness (breakdown, risk, phased release)
  • AI review + human review operational design (quality improvement & learning promotion)
  • Development process establishment (tickets, DoD, release procedures), etc.
