Software Development Engagement Models
Renvric offers engagement models for different levels of scope certainty, client ownership and delivery continuity. Choose between a dedicated team, staff augmentation, project based development, fixed price or time and materials by deciding who owns priorities, how stable the outcome is, how change will be handled and what commercial predictability is required.
Start your project
Choose from the shape of the work
The model should follow the work, not precede it. A stable deliverable may support fixed price; an uncertain roadmap may need time and materials or a dedicated team. Staff augmentation fits a client-led delivery system, while project based development assigns Renvric responsibility for a bounded outcome. Commercial terms still need to reflect the specific scope and market.
Available models
Stable cross-functional capacity for a continuing roadmap with shared outcome governance.
Selected specialists join a client-led team and use its priorities, methods and controls.
Renvric leads delivery of a defined outcome through an agreed project structure.
An agreed price for defined deliverables under explicit assumptions and acceptance criteria.
Approved time or capacity supports evolving priorities with transparent spend and forecasts.
Five decisions before selecting a model
Outcome ownership
Decide whether the client or Renvric owns day-to-day delivery of the result.
Scope certainty
Separate stable requirements from questions that must be answered during the work.
Priority authority
Name the person who can order work and resolve stakeholder conflict.
Commercial control
Choose how price, capacity, milestones, forecasts and changes will be approved.
Handover
Define how knowledge, repositories, documentation and operational responsibility will transfer.
Terms that every model needs
Each agreement should define scope or capacity, roles, decision rights, client inputs, access, governance, quality, security responsibilities, intellectual property, third-party costs, acceptance, invoicing, change, notice, continuity and exit. The model name does not resolve these matters by itself.
Pricing and market information
Rates, currencies, taxes, working hours and contracting arrangements should be confirmed for the specific engagement. Country pages may explain approved local commercial context, but no page should imply a legal entity, office, local team or standard price without current evidence and owner approval.
How a recommendation is made
Renvric should test the desired outcome, known scope, client delivery maturity, required skills, timing, budget control and procurement constraints before recommending a model. Where those inputs are incomplete, a short discovery step can establish a credible basis. The recommendation should explain why the model fits, which risks it transfers or retains, and which conditions would require it to change.
All engagement models
Common questions
Which model gives the most flexibility?
Time and materials and dedicated teams support regular reprioritisation, but both need clear budget, capacity and decision controls.
Which model gives the most price certainty?
Fixed price can provide certainty for defined deliverables under stated assumptions. Changes and failed dependencies still need contractual treatment.
Can a project use more than one commercial model?
Yes. Discovery may be fixed, implementation may use time and materials, and later support may use retained capacity. Boundaries and transitions must be explicit.
Who owns intellectual property?
Ownership and licensing depend on the contract, including pre-existing materials and third-party components. Confirm the terms for the engagement.
What information is needed for a recommendation?
Share the outcome, current team, scope certainty, desired responsibility, target timing, budget context and procurement constraints.
