1. Schedule

1.1 Project managementThe project assignment is splitted into logical stories and those stories are splitted into individual tasks. Each task has initial time estimation which are added together for story level time estimations.

The time usage is followed at task level and monitored during the project. Project management is designed to be light and flexible. New stories and tasks can be created when needed.

PICTURE: The project task board initial state. (Note: Some tasks and stories are missing)

Totally hour estimation is 364 hours. The hour realization is tracked by story level and compared to initial estimations at the end of the project. Realization is also tracked during the project to keep progress estimations up-to-date.

2. Log

2.1 Daily hour log

The hour log was kept separate from the task and story based time log so there are differences between these two logs. The accuracy of the time logs is estimated to be around 10-20% but they gives a good overall view about time usage of this project.

3. Summary

The project schedule was working as planned over the feature development phase (weeks 2 to 5). Then during the testing and documentation phase (weeks 6 to 8) the available resources were decreased significantly due the time demand of other university courses and projects. This can be seen at the burnout chart picture.

The time estimations of the tasks and stories were estimated 25% over the realization. This is considered to be acceptable and did not cause any problems.

Especially purchase of the components and implementation of the bluetooth connectivity took more time than estimated. The problem with the bluetooth was caused by lack of documentation and problems with the used bluetooth module and Windows 7 operating system bluetooth setup.

The actual feature implementation of the features took about about 25% less time than estimated. Main reason for this might be the good testing environment that made it possible to implement all the features with real hardware before designing the PCB ans schematics.

Here are the top level project phases.
