What's your suggestions for this WBS approach?

The Best Glide Ratio System (BGRS) will automatically calculate an aircraft's glide ratio, time remaining in the air, and automatically recommend a suitable airfield to the pilot based on these calculations. In turn, this reduces the workload pilots experience during an emergency that requires an emergency descent, such as during a propulsion system failure. The BGRS program is in the concept development and planning stage.

BGRS will use a waterfall or predictive life cycle. The WBS structure for this life cycle contains the project name at the top level, while project phases and major deliverables are on the second level (PMI, 2019). A bottoms-up cost estimation was used to derive the labor hours associated with each WBS. The bottom-up estimates the work at the lowest level of detail and is considered more accurate than other cost estimating methods (PMI, 2024). Labor rates for the various disciplines were then applied to the hours to come up with budget for each WBS.

Below are the WBS for BGRS along with the budget associated with each WBS. In summary, the total budget ask is ~1.6M.
