52. 3 main risky things
and solving them with
blade

53. #1 Agreement on work
before technical
expertise

55. Solving #1
Client management vs
Company management
- Indicate core value for a POC
- Agree on communication persons
- Describe final expectation from POC
- Discuss business value
- Agreement on technical expectation review

56. Solving #1
Company management
vs
Company team

- Discuss the team
- Make technical expertise
- Prepare questions to client
- Rough estimate

57. Solving #1
Company team and management
vs
Client side

- Create a vocabulary
- Review technical expertise
- Agree on release date
- Approve on starting POC

58. #2 Overengineering

59. Silver bullet they said . . .

60. Solving #2
- Do not experiment to much
- Do not afraid of making things simple
- Do not make things too simple
- Do not think that you know more then client knows
about its business
HOW TO REACH THIS???

61. Solving #2
- Use your stable stack
- Always write tests
- Use BDD and DDD:
* from BDD scenarios
* from DDD fault tolerance
- Сutting corners: only basic features

62. #3 Skill underestimation

63. BEST TEAM EVER

64. Solving #3
- Matrix skill: easy to see what resources you have
- Certification: preparation process is a benefit
- Internal Hackathon: looks like a small POC
- RELAXATION: POC is stressful. Be calm.
