Explanation:
The given letter is from the owner of the Sunny side apartment complex to the manager of the buildings and it is regarding the replacement of the showerheads in the buildings and the statement is made making an assumption that in the future there would be more profit if they make the same changes to more profits.
The owner has stated bis perspective by taking into account a generalized view point and also given the lack of evidentiary values creates a dearth and paucity in the statements made by the owner. The weakness in the statement is purely created due to the general assumption of the owner and not based on the data or substantial evidence of the observation made in the changes in the building.
The Drawbacks have been mentioned by the owner but they have not been considered seriously as negative possibilities that might cause them future expenses. The other important aspect is the lack of the consideration given to the various factors. The owners statement are primarily focused on the profits and they negate all other aspects such as the water pressure and the exact data which he clearly states is unavailable till now.
[Without considering the exact usage of the water based on the number of people who
are using, the exact number of shower heads, the total amount of water consumed.
the average supply of water in the building, the totla profit that they might make, the
overheads cost and the cost of installation of the new shower heads all need to
stipulated and then considered on a serious note before they proceed with the
changes.
The owner needs to conduct a proer study of the data rather than making a hyperbolic
assumption that they would meet profits, given that there is not guarantee for the
same.
It is essential for the statement to also consider the extent of profit that they could
make (brought the proposed change.
To conclude, it is essential for the statement postulated in the letter to consider more
comprehensive aspects before arriving at the conclusion that would only undermine
and weaken the perspective of the given letter.
