223 | ### Shared Responsibility | 223 | ### Shared Responsibility |
224 | 224 | ||
225 | -When the government technicians were responsible for deploying the project, the | ||
226 | -developers lost track of what happened after code was delivered. After adopting | ||
227 | -CD, they felt more responsible for what was getting into production. CD | ||
228 | -influenced developers on taking ownership of the project. In the end of the | ||
229 | -project, we noticed that the entire team was working to improve the CD pipeline | ||
230 | -since they want to their new features in production. | ||
231 | - | ||
232 | -Interestingly, the CD pipeline also made the government requirements analysts | ||
233 | -feel more responsible for the project. They were an active part of the pipeline | ||
234 | -and that engaged them on the whole process. In the end, they were even actively | ||
235 | -creating issues and discussing them during the development process. | ||

238 | -[//]: # (TODO - depois deles entrarem de fato no pipeline, ou seja, validar em ambiente de homologação, criando issues e comentando nas issues do repositório é que de nosso processo empírico de desenvolvimento predominou até o fim do processo) | ||

241 | -### CD pipeline protocol between Government and Development | ||
242 | - | ||
243 | -In the beginning of the CD pipeline use, a bottleneck arose at the acceptance | ||
244 | -tests step due to delays in reviewing new features and starting the next step. | ||
245 | -These delays occured because the government analysts, responsible for | ||
246 | -reviewing, were sometimes busy or didn't have schedule this work. Furthermore, | ||
247 | -after the acceptance of the new code, there was a bureaucracy in the government | ||
248 | -IT infrastructure that often made us to wait until 3 days to get the production | ||
249 | -environment access and then to start the deployment step. This problem was | ||
250 | -softened when we clarify our pipeline for these analysts and they organized | ||
251 | -their schedule to speed up reviews and production access requests. | ||
252 | - | ||
253 | -### Work in small batches developed trust in our relation with government analysts | ||
254 | - | ||
255 | -In the first three releases, government requirements analysts were validating | ||
256 | -all features to be released only at the end of a delivery cycle which often | ||
257 | -took almost four months. However their superintendents requested monthly | ||
258 | -reports about the project progress and this brought pressure on them which in | ||
259 | -turn put it on us. When we started to make continuous deliveries, we really delivered | ||
260 | -intermediate and candidate releases. Thus, the analysts could have validate a | ||
261 | -small set of features, making possible more accurate feedbacks and better | ||
262 | -reports for regular meetings with their superintendents. As a result, we | ||
263 | -gained their trust and they also gained trust of their chiefs about the SPB | ||
264 | -project management. | 225 | +Before the adoption of the CD, the developers team could not track what happened to the code |
226 | +after its delivery, since government technicians were the only responsibles | ||
227 | +for deploying the project. The implementation of the referred | ||
228 | +approach influenced developers on taking ownership of the project because it | ||
229 | +made them feel equally responsible for what was getting into production. | ||
230 | + | ||
231 | +Interestingly, the CD pipeline had the same effect on the team of requirements analysts. | ||
232 | +They were an active part of the pipeline and became more engaged on the whole process. | ||
233 | + | ||
234 | +After the incorporation of the pipeline into the work process, analysts | ||
235 | +became more active in opening and discussing issues during the platform evolution. | ||
236 | +Additionally, developers worked to improve the CD pipeline in | ||
237 | +order to speed up the process of making available, in the production environment, | ||
238 | +new features for the platform. | ||
239 | + | ||
240 | + | ||
241 | +### Synchronicity between Government and Development | ||
242 | + | ||
243 | +Despite the positive impacts that the CD pipeline brought to the project, its | ||
244 | +implementation was not easy at first. The good performance of the CD pipeline | ||
245 | +depended on the synchronicity between the teams of developers and government | ||
246 | +analysts, so that the work of one could be initiated immediately after | ||
247 | +the delivery of the work by the other. Initially this concern was not | ||
248 | +contemplated in the agenda of the governmental team, which generated delays in | ||
249 | +the validation of the new features of the release. This situation combined with | ||
250 | +governmental bureaucracy (up to 3 days) to release access to the production | ||
251 | +environment resulted in additional delays for the deployment step to begin. | ||
252 | +This problem was softened when the analysts realized the impact of | ||
253 | +these delays on the final product and decided to allocate the revisions in its | ||
254 | +scale of work and to request the access to production in time. | ||
255 | + | ||
256 | +### Strengthening trust in our work relation with the government | ||
257 | + | ||
258 | +Continuous delivery was also a tool that helped to strengthen trust in the | ||
259 | +relationship between developers and government analysts, as well as between the | ||
260 | +latter group and its superiors.Before using CD, analysts had access to the | ||
261 | +features developed only at the end of the release, usually every 4 months. | ||
262 | +However, this periodicity did not meet the requirements of their directors, who | ||
263 | +demanded monthly reports on the progress of the project. With the | ||
264 | +implementation of the CD, intermediate versions became available, allowing | ||
265 | +analysts to perform small validations over time. The constant monitoring of | ||
266 | +the development work brought greater security to the governmental nucleus and | ||
267 | +improved the interactions of these with the team of developers. | ||
