1. Avoid the disaster Building new Software solutions some tips Marco Molteni - @marcomolteni
2. Where my experience comes from 18 Years in IT consulting Working with the latest technologies in new projects I worked with … CSS Health Insurance, no 1 in CH ZKB, bank no 1 in ZH SBB, biggest transport company in CH HPE, Appian (USA), Raiffeisen (RO), SJP (UK), CIB (HU), Banca Intesa (IT), Norkom - BAE (BE), IBM (IT), Accenture (SK), Crédit Agricole (FR), LCL (FR), Natixis (FR), ... Many roles but a big passion for building SW Marco Molteni - @marcomolteni
3. Recommendations • Define the business vision • Define the business requirements • Split the business requirements in small products units • Give a business value/priority to these units • Choose / build a tech solution according to the business value of the units • Don’t let your IT to define your business (processes / priorities etc.) • Reduce the complexity and of the risks Build the technology around your business / clients requirements, don’t build the business around you IT solution Marco Molteni - @marcomolteni
4. • SW costs a lot to build, usually much more than initially estimated. • Maintaining the SW can cost even MORE • Every component added multiplies the complexity, increase the issues and … the costs • Pre-build frameworks and platforms are hardly configurables / updatables and there is a vendor lock-in • The interaction between different modules / services / providers increase the errors -> time -> costs • In 3-5 year your technology will be obsolete and will require to be renewed Better to Know Marco Molteni - @marcomolteni
5. Maybe it’s already there • Before your money finish in the project check if a similar solution exists … anywhere • Any existing similar SW in the world will be in competition with your solution. Double check that nobody is cheaper / faster / better than you. Marco Molteni - @marcomolteni
6. Building a new software means ... Better to Know - 2 Marco Molteni - @marcomolteni
7. Expect to be disappointed! Every participant understands the goal differently. Better to Know - 3
8. Big Vision … small steps Marco Molteni - @marcomolteni
9. Have a minimum product from Month 1 … improve IT every 2 weeks • Deliver an improved product every 2 weeks. • Verify with the stakeholders that the product is following the requirements • Stop it if the direction is wrong Marco Molteni - @marcomolteni
10. Choose a Product Owner Marco Molteni - @marcomolteni
11. A Product Owner • Defines the product goals • Translates the needs of the clients in requirements • Decides what’s coming in the next product increment • Gives the priorities • Interacts with the stakeholders • Defines the business added value of each feature • He has expertise in the business, not required in IT Marco Molteni - @marcomolteni
12. Example of Product Increment The IT estimates the cost of each feature. The Product Owner decides what to include in the next 2 week product increment according to the business value and the cost of the feature. Marco Molteni - @marcomolteni
13. … if the idea is wrong with small steps Fail as soon as possible Marco Molteni - @marcomolteni
14. Avoid the Last Tech Fashion if not clear • No expertise in the market • No users • High costs • It changes very quickly Marco Molteni - @marcomolteni
15. Avoid the Vendor Lock-IN • Every part of your infrastructure can be moved to a different provider • Your data can be easily migrated to a different system Marco Molteni - @marcomolteni
16. Common Vendor Lock-IN and practices • Drug dealer style : first version of the SW is cheap (promo), the migration to the new version cost much more. • The provider is not interested / cannot develop for you a requirement, it multiples 10x the price to avoid it. Official reasons: complexity, or you didn’t communicate it at the beginning. • Without the code source, every change must be done by the same company. • For the first phase (contract 1) everything is ok. From the 2nd phase everything become more complicated and expensive. • Your data is at a service provider, every access as to be paid because it requires effort from the provider and you didn’t declared explicitly in the contract. • The new features / sw are paid by you, ‘because only you want it’. The feature is re-sold to other clients for a discounted price or maybe you paid something that was already developed for other clients. Stories based on real cases (more details on request). Marco Molteni - @marcomolteni
17. Other Examples of Vendor Lock-IN • Every software has problems. You have to pay to solve it because: you didn’t required that particular feature or combination of features, you are not able to use the software correctly. • A new technology come on the market (mobile, virtual etc.). ‘Sorry 3 years ago you didn’t ask for it the integration is very expensive’. • The license is not expensive, every change / new feature (Professional Service) is paid at very high market rates because done by specialists (usually junior consultants at the company) • Special features of Cloud providers: ◦ Serverless functions ◦ ‘Cheap’ DB and data storage in AWS • Every non standard feature in common software like databases (Oracle etc.) • Every Blockchain (Immutable database) is a lock-in by definition Marco Molteni - @marcomolteni
18. Remember • Technologies change very frequently • People change • Companies change • Relationships change - Adidas and Puma come from a conflicting brothers • SW is very complicated, risks and complexities are exponential. Limit the risks and monitor the process! • If you don’t understand it, probably you don’t need it but possibly you will be billed for. Marco Molteni - @marcomolteni
19. How To reduce the Lock-In Risk • Use standards as much as possible • Be sure that more providers / companies can improve your original infrastructure • Be sure that your software can be improved at least on a 6 month basis - banks have 2 major releases / year, FAANG have daily / weekly releases • Challenge the offer of the providers ◦ Costs, new features, integration of xyz • Be sure that your critical data can be exported and read with Notepad on your PC Marco Molteni - @marcomolteni
