SYSE.24:3 - Forces
The following eight tensions recur in this decision.
| Force | Tension |
|---|---|
| Fast availability and later change | A ready product or provider arrangement may reduce time to first use while increasing dependence, migration cost, or change latency. |
| Internal capability and immediate delivery | Internal development can grow capability while delaying the result; an arrangement that relies on provider Work can make the result available sooner while displacing learning or making it dependent on continued access. |
| Comparable result and heterogeneous means | Every option must obtain the same result under the same acceptance conditions, while the Agents, Work, Methods, Systems, and relations can differ radically. |
| Low entry price and full burden | A visible price is easy to compare, while integration, assurance, data, support, change, and exit burdens often decide the outcome. |
| Provider freedom and engineering assurance | The Agent performing provider Work needs freedom to choose its Methods, while the receiving engineering team still needs evidence that the accepted result and interfaces satisfy the stated use. |
| Technical choice and specialist authority | The engineering team must connect the arrangement, while specialist practices retain their decisions, Methods, and authorities—for example, for commerce, law, finance, governance, organization, operations, safety, security, and assets. |
| Option generation and option choice | The engineering team must generate materially different complete arrangements before the deciding Agent applies C.11 to the fixed OptionSet; generating and choosing are different Work. |
| Local result and affected Systems | An arrangement may help achieve the project result while transferring work, risk, lock-in, delay, or harm to affected Systems such as users, maintainers, partners, and providers. |
