The Development Ministry oversees the construction of buildings on your planet. You can monitor your build queue and subsidize the construction of buildings through the use of Essentia to build them faster. The higher the level of the building the more buildings you can have in your queue. The number of projects that can be placed in the queue is the level of the ministry plus 1.
NOTE: The build queue is a queue, which means that the buildings in the queue build in series (one after the other), not in parallel (at the same time). Therefore if you have one building already in the queue which takes 5:00 to build, and you add another building which takes 1:30 to build, then the second building will be completed in 6:30.
5:00 + 1:30 = 6:30
Upgrading the Development Ministry beyond level 4 might not be worth the expense, depending on your play style. Each upgrade puts a drain on your hourly resource income. At level 4 you can have 5 buildings in your queue already. There are no other buildings in game that are dependent on having a Development Ministry.
