DAR: 5 keys to demystify modernization decisions

Decisions are hard. Every “adulting” meme you see on social media reinforces that core belief. Government leaders charged with making modernization investments live this reality every day.

Federal leaders understand the imperative for modernization—reducing operational costs, increasing speed and agility, and being more responsive to customer and employee demands. In our Voice of our Clients interviews, federal leaders cited modernization as the top business trend impacting their organizations.

Making the decision to modernize? Not difficult. Making the decision on how to modernize? Much more challenging.

In any moment of decision, the best thing you can do is the right thing, the next best thing is the wrong thing, and the worst thing you can do is nothing. ~ Theodore Roosevelt

What are the core aspects of business modernization?

Business modernization can describe a few different approaches, depending on the type of industry as well as the needs and goals of an organization. A modernization consultant will help you determine which type (or types) is right for you.  

5 major types of modernization:

1. Application modernization: Updating or rebuilding legacy systems with microservices to enhance functionality, improve user experience and increase portability. 
2. Legacy modernization: Replacing or redesigning outdated, inflexible systems to align with more modern business needs and expectations.
3. IT modernization: Evolving overall IT infrastructure by automating workflows, consolidating systems and introducing cloud-native technology.
4. Mainframe modernization: Modernizing legacy systems into advanced architectures with APIs or cloud integration to boost agility and maintain critical functions.
5. Cloud modernization: The ongoing process of optimizing and modernizing applications and data to be cloud-friendly, often with DevOps, AI and managed services.

What is DAR, and how does it help with modernization?

Decision Analysis and Resolution, or DAR, refers to a structured and collaborative evaluation process used by modernization consultants to compare potential alternatives for technology, business and system initiatives. The DAR process—part of the Capability Maturity Model Integrated (CMMI) Level 3—supports organizations in identifying architectural options and selecting the best approach. 

A mature DAR process promotes objective, informed decision-making, which reduces risk and promotes success when tackling hard-to-reverse decisions. DAR is also useful for evaluating specific components of the architecture, either iteratively or on an ad hoc basis.

How to modernize your organization with DAR

How do you, as an agency, IT or business leader, make the best decisions regarding how you modernize? You need a structured approach that enables you to make informed choices regarding to-be architectures, based on a thorough analysis of what will work best within your organization. Your decision-making approach must consider not only the latest technology available on the market but, more importantly, your organization’s unique constraints, policies and ways of working.

The DAR process guides the activities necessary to select the optimum frameworks, technologies, platforms or products to meet business needs. Using DAR, architects help organizations analyze possible decisions using a formal evaluation process, comparing the merits of identified alternatives against established criteria. DAR applies to build/buy analysis, options analysis and the feasibility of various approaches to achieving both technical and business objectives at the enterprise level or for a given modernization initiative.

Applying the DAR process with confidence and collaboration

DAR is often considered a technical evaluation process. That is an oversimplification at best. An effective DAR requires collaboration so that all stakeholders have confidence in the decisions made. 

An open, transparent DAR process encourages active participation in decisions while supporting holistic and well-thought-out decision-making based upon objective criteria. When collaborating with clients to establish an effective DAR, look to instill some important principles within the process.

Instill these 5 key DAR principles for your modernization:

1. Define an approach
2. Agree upon evaluation criteria
3. Apply organizational priorities
4. Evaluate based on results
5. Document 

1. Define a consistent approach for use across the organization
You should formally define, document and deploy your DAR structure and process to ensure consistency and institutionalization across your organization. This enables IT and business teams to make effective use of the process without confusion over how to begin. Leadership buy-in to the DAR process is vital to instilling confidence in the decision-making process.

2. Develop evaluation criteria that are traceable and easy to understand
DAR teams must establish traceable evaluation criteria for requirements, scenarios, business case assumptions, business objectives or other documented sources. Spend ample time on establishing your evaluation criteria to ensure a targeted, yet holistic, focus. Typical criteria types include business requirements, technology limitations, environmental impact, risks, initial investment, lifecycle costs and compliance with agency-level or federal-wide standards.

3. Apply organizational priorities to shape evaluation criteria
DAR members should represent the broad stakeholder community, including business, technology, security and compliance. An architect can support the DAR team in arbitrating the importance of each stakeholder’s priorities as they work to establish thorough evaluation criteria. Involve your key decision-makers throughout the DAR process, particularly when establishing evaluation criteria, to avoid late identification of requirements. 

This prevents subsequent debate regarding evaluation outcomes, based upon what some might see as incomplete or inappropriately prioritized criteria. Include security and compliance criteria to avoid selecting an alternative that cannot achieve authority to operate.

4. Evaluate based upon demonstrable results and complete information
Avoid using only vendor product materials when evaluating against criteria. Instead, perform your simulations, modeling, prototypes and pilots as necessary to exercise evaluation criteria, methods and alternative solutions. 

Agencies should apply the most thorough evaluation process possible in selecting a solution. Changing criteria partway through the DAR can affect the measurement work already completed and force re-evaluation of tools against the new criteria. If you must make a decision with incomplete information due to schedule and resource constraints, identify the risks, monitor them closely and re-analyze the alternatives later.

5. Document, document, document
Teams must document the results of the evaluations—fully and carefully. If your team identifies new alternatives during the DAR, document the rationale for the addition of these new alternatives or methods, as well as any changes to the evaluation criteria based upon interim evaluations. 

Document the results and rationale for the recommended solution. As responsibility for a system or technology changes from one resource, team or organization to another, it is important that people joining your project team can readily access data showing how they reached previous decisions.
