Software Development Methodology v Reality

Last week my company held its operations summit to review how we deliver solutions to our customers. We presented best practices and discuss tools, models, and approaches to understanding, designing and implementing software solutions.

This discussion made me think back on how the ideals of methodology differ from the reality on the ground. Everyone can agree on the value of having complete, ironclad requirements before development begins, but we all know that this is unrealistic. Among the many ways that requirements fall short is that they are incomplete and inaccurate. Some requirements ultimately are thrown overboard because the cost of implementing them is higher than the business value, and others because they lead to a business process that is too complicated or otherwise unworkable.

More recent methodologies such as Agile and SCRUM are more explicit about dealing with uncertainty. Perhaps we need to be more direct in dealing with inadequate requirements, setting a lower threshold of completeness and accuracy before development begins.

Even if we could make the requirements one hundred percent complete and one hundred percent accurate, change always rears its ugly head. Seldom does the consensus of management remain solid forever, and business rules may change from exogenous factors such as changes in laws and regulations.

On the other hand, perhaps we need to cling to the abstract ideals, even knowing that in our human world we will fall short.

Key Concepts for Microsoft Dynamics 365: Tenant, Instance, App and Solution

Updated 8/15/2022 To understand Microsoft Dynamics 365 (formerly Dynamics CRM) and Power Apps, you need to learn some new terms and concepts that may be a bit different from what you know from databases and solutions that are hosted on premises.  These concepts also apply to Power Apps.  The main difference is that with Power Apps you are not starting with a Microsoft app but more of a blank canvas for your custom apps.  This post introduces some key terms and how these concepts are important for planning your implementation. While Dynamics 365 is still available on premises, it is most commonly deployed on the Microsoft cloud.  This blog post discusses only cloud implementations. Microsoft has multiple clouds such as commercial and government community clouds in several countries. We start with a Microsoft tenant .  A tenant is the account you create in the Microsoft Online Services environment (such as Office 365) when you sign up for a subscription. A tenant contains uni

Understanding Dynamics 365 and Office 365 Admin Roles

Managing Dynamics 365 instances If you run Microsoft Dynamics 365 (formerly Dynamics CRM) in the Microsoft cloud, you need to understand how your Dynamics instances relate to Office 365 and choose which of your administrators receives which roles and permissions to manage Dynamics 365. In on premises deployments, your network administrator would create and delete user accounts.  The Dynamics 365 admin would then assign permissions to users in Dynamics 365. This post explains three administrator roles: Office 365 Global Administrator Dynamics 365 System Administrator Dynamics 365 Service Administrator You may think that the Dynamics 365 system administrator would have power to do all the actions needed to manage Dynamics 365, but this is not the case. What's different in Microsoft cloud deployments is that licenses and user accounts are managed in Office 365 by an Office 365 Global Administrator.  This role is analogous to a network administrator for an on premises
