Describe the two basic functions of the qualitative risk analysis process and explain why a project manager should perform a qualitative risk analysis prior to quantitative risk analysis.

What type of information does a business risk analysis give?

1. Describe Risk Analysis and its impact on financial considerations for new projects.
2. Discuss how the Risk Analysis process allows organizations to meet their due diligence and fiduciary duty.
3. Discuss the two key times the Risk Analysis output will be used.
4. Discuss the elements of a Risk Analysis, including time and cost variables.

What sort of qualitative behaviour does a stock following a process of the form
$d{S}_t=\alpha (\mu -S_t)dt+S_t\sigma d{W}_t$
exhibit? What qualitative effects do altering $\mu$ and $\alpha$ have? What effects do they have on the price of a call option?
My try:
Assume that $\alpha <0,$. If $S_t<\mu ,$, then $\alpha (\mu -S_t)>0.$. Similarly, if $S_t>\mu ,$, then $\alpha (\mu -S_t)<0.$. This means that if $\alpha <0,$, then $S_t$ is mean-reverting.
Conversely, if $\alpha <0,$, similar analysis above implies that $S_t$ is trend following.
In the derivation of Black-Scholes call option price, mean rate of a geometric Brownian motion does not affect the price as it will be changed into risk-free rate.
As the volatility is the same, $\alpha$ and $\mu$ do not have any effect on the price of a call option.
Am I correct?

Describe the risk analysis approach and the steps in a detailed or formal risk analysis

The set of primitive recursive functions is [...] the smallest set containing the constant 0, the successor function, and projection functions, and closed under composition and primitive recursion.
My question is about the way composition, which does not seem very intuitive to me
If $f$ is a $k$-ary function and $g_0,\dots ,g_{k-1}$ are $l$-ary functions on the natural numbers, the composition of $f$ with $g_0,\dots ,g_{k-1}$ is the $l$-ary function $h$ defined by
$h(x_0,\dots ,x_{l-1})=f(g_0(x_0,\dots ,x_{l-1}),\dots ,g_{k-1}(x_0,\dots ,x_{l-1})).$
Is this just another way of stating composition as one may understand it in real analysis: that if we have
$g:{\mathbb{N}}^l\to {\mathbb{N}}^k\text{and}f:{\mathbb{N}}^k\to \mathbb{N},$
then we can define some composed function
$h:{\mathbb{N}}^l\to \mathbb{N}?$
Or, would there be any "risk" at looking at the definition in this simplistic way?
