The Last Project Scaling up BLUME2000 Prepare BLUME2000 Shop Platform and development process for new cross channel business models: From project to product TIMELINE ▪ October 2020 Three teams started ▪ October 2020 to January 2021 Ramp Up Phase with trainings and workshops ▪ January 2021 Start development ▪ May 2021 Golive MVP with 0,5% traffic ▪ May 2021 to June 2022 Slow, continuous traffic ramp up ▪ October 2021 Scale one more developer per team in ▪ January 2022 Split into four teams in ▪ June 2022 Reached 100% traffic
3. How did we do this?
4. Independence on three levels. 1 Product separation 2 Organization separation 3 Technology separation
5. Level 1 // Product separation with help of DDD // Cross Channel (!) • enter shop or store • login/registration • preferences • information/faq pages • inspiration/content pages • overview on brand • reduce products • product detail page and in store displays • upselling products • shipping options • availability / stock • pricing • use basket • discounts • checkout and cash register • payment • last check • change orders • delivery status • customer care • delivery customer & -preferences productdetails & -relations, stock, price & discount orders, deliveries & finance Tolerance Data KPIs DISCOVER DECIDE FULFILL high middle low bounce rate, visits, visit length, page count, conversion to next page add-to-basket rate, fast visit length & page count conversion rate, fast visit length, low page count
6.

11. Reasons for success Prepare through extensive ramp up phase Force Small Teams, include Stakeholders Deliberately control scaling Mob programming only POCs in one team; rollout to other teams Trunkbased Zero Downtime Deployments Quality over Quantity
12. What didn't go well? Underestimated necessity for a mature product organization Missing methods to develop product organization Agile Working Method has prerequisites in the rest of the organization that first had to be established 1 2 3 - Inappropriate culture & lack of leadership skills made it very tough - Support from Scrum Masters / Agile Coaches would have been helpful - There is no mob-product-management
13. The role of leadership.
14. The Acceleration Correlation 1 2 3 4
15. Everybody is a leader. The elevator is going up and down You are not a Boss, you are a Co-Creator! - Discuss vision with owners & supervisory board - Discuss strategy with other leaders - Help teams on an operational level Be active on all three levels - Guardian of independence - Coach teams to self-organize - Sparring partner for architecture discussions Change Agent for the organization Servant Leader for the teams + + + +
16. The Boss MANAGEMENT- UNDERSTANDING “Assertiveness & determination are among the most important qualities in my job.” EMPLOYEE- EXPECTATION “My employees like manageable tasks that can be solved quickly. It doesn't bother anyone if something repeats itself." "I always have to stay on top of things and know what to do next." "Most of the time I have to make decisions on my own so we can keep up the pace." "My employees look up to me - so they are happy about my praise or small bonus payments when they have done something well." “Ideally, my employees have a clear idea of exactly what to do and what the result should look like.” BOSS
17. The Co-Creator MANAGEMENT- UNDERSTANDING “I mainly act as an enabler here. My curiosity and enthusiasm for innovation have brought me to where I am today.” EMPLOYEE- EXPECTATION “Each employee here brings a special knowledge or talent and is driven to solve problems.” “My job is to enable employees to fully carry out their tasks and to support them in achieving their goals." “We all bring a very high level of technical expertise to the table. I have to be able to combine different perspectives." "Even adversers can and should freely express their opinion here, often this leads to better solutions in the end." "The employees here would like to contribute their skills and are looking for a highly competent manager with whom they can exchange ideas." CO-CREATOR
