When time and budget are tight, it's tempting to follow the "happy path" in testing. But be careful: it may be a path that brings your program great unhappiness. From William E. Novak and  Linda Levine CMU SEI Sept 2010 Success in Acquisition: Using Archetypes to Beat the Odds paper and see webpage

Purpose 1 New Small Business - Cloud Support Model
Purpose-To enable a visual model to acquire new business owners to adopt cloud services.   

Purpose 2 Cloud Service Provider Delivery Model-Service 
2. ​The purpose of this model intends to allow a cloud service provider a way to design offers for generic use across any industry.  

Outcome - Key Control for Segregation of Duties GAAP/GARP
3. The purpose of this model incorporates the variables of different components for completeness and monitoring scope for any master data update or create activity.  

Outcome - Key Controls for SOX 404 Assurances
Monitoring all activities for segregation of duties controls - in a control chart.  The model ensures a completeness criteria for cost structuring of any new offer or acquisition integration.  

GAAP-Non-GAAP Revenue
The primary inputs shown on this diagram trigger the leverage points for many of the dependent processes and management of an offers revenue treatment.  

Completeness - Supplies the various parts of the whole 
Organization or Agency models - simulations 
Stock and Flow models enable simulation of the proposed design with a better view into results of any proposed changes.   

Enterprise Architecture Value 
Predict changes and prepare for complexity based on the risk using the components simulated in stock and flow diagrams.  

Model and simulate the "as is" and "to be" or monitor as the way to ensure your architecture stability and when investments need to be made in a next generation strategy.  

Business Architecture Value
Use the whole and parts (stock and flow child) to better understand the "current state" measuring the transition to the desired state on the journey to a performance model.   

The model applies the rows from Enterprise Architecture as prescribed by Zachman Ontology v3.  Based on the way business requirements need to be applied to technology solutions.  


Row 1 - Executive - Context of the organization

Row 2 - Business Managers - Business Process connectivity

Row 3 - Architects - Systems - The transition from Business to Enterprise Architects.

Ideally-the offer management capability serves as one of 5 capabilities which must be in place to meet both financial and quality certification criteria for the majority of companies.  

Highway Analogy
A 5 capability model enables the audit relationships between different master record management audit log tracking for SOX to be used by quality management to align with corporate policies which intend to guide decision making within any size and any type organization or agency.  

Applied 
The system model would be copied by an organizations resource and inputs applied to a stock and flow diagram as prescribed in associated models.  Herein we must assume the whole and each of the stock and flow simulation models the component parts.

There is a general belief that wind and solar will enable us to get fossil-fuels-use to net-zero. This is, unfortunately, impossible as an examination of only some limitations and constraints associated with solar and wind energy will show. Solar panels and wind turbines have now been used for many years, but until now they represent only a tiny fraction of total energy use (not just electricity but all forms of energy).  In 2020, wind accounted for 3% of the world’s total energy consumption and solar amounted to 1% of total energy. Thus, the combination of wind and solar produced only 4% of world energy in 2020. How long will we have to wait before they can generate enough energy to power the world? The climate emergency will not wait.  Solar panels and wind turbines have average lifespans of around 15 to 30 years, then they need to be replaced. However, the manufacture of the replacements will require fossil fuels since one cannot use wind or solar to build wind and solar. Further, solar panels do not supply enough energy. The net-energy gained from solar panels is only about 3.9:1. This net-energy ratio is known as ‘energy return on energy invested’ (EROI) and is critically important.  Unfortunately, the EROI of solar is far too low to power a modern industrial society, which requires an EROI of about 12:1. There is also the question of space. Renewable energy sources can take up 1000 times more space than fossil fuel – that is bad news for agriculture and food production in a world that is already experiencing food shortages because of global warming. If you take these limitations into consideration, then it becomes clear that solar and wind cannot solve our energy problem – they are a fix that will inevitably fail. 

Simple Bass diffusion modified from Sterman Business Dynamics Ch9. Compare with the SI infectious disease model Insight 584, to which we added churn and duplicated it to model a 2 sided marketplace..

In this 2-sided market model -- take etsy for example --  the adoption rate of end users is also a factor of how many vendors the company has on-boarded.  You can control the impact on end user adoption via the Choice Impact Factor.

Conversely,  the rate at which vendors will be on-boarded is a factor of the perceived opportunity they have to sell their wares.  You can control the rate at which suppliers are on-boarded via the Opportunity Impact Factor.
