Governance of Agile Delivery

Introduction

The Agile methodology brings in alternate approach to traditional project management, where success was hard to get. Typically used in software development, Agile methodology help businesses respond to unpredictability. By focusing on the repetition of smaller work cycles as well as the deliverables, agile methodology is described as “iterative” and “incremental”. In waterfall, development teams only have one chance to get each aspect of a project right. In an agile paradigm, every aspect of development viz. requirements, design, etc. is continually revisited. When a team stops and re-evaluates the direction of a project every two weeks, there’s time to change course. Because teams can develop software at the same time they’re gathering requirements, “analysis paralysis” is less likely to impede a team from making progress. Agile development preserves a product’s critical market relevance and ensures a team’s work doesn’t wind up on a shelf, never released. Considering the value delivery that the Agile methodology promises, its adoption has been on the rise and today most organizations, including Government are embracing Agile approaches.


Governance of Agile Delivery


Critics say that Agile methodology is all about working in an unstructured way and for that reason, they believe that governing agile practices is always a challenge. While some of the Agile principles appear to support such criticism, there are many cases where organizations have successfully implemented processes and frameworks towards governance of Agile practices. Agile practitioners believe that because the agile methods are designed to be self-assuring, when practiced right, there exists built-in governance and accountability.


More so, the agile practices are more collaborative and operates continuously, requiring the stakeholders to review and test the deliverables on a continuous basis and helps the team to take alternate course of action as may be needed. Collaborative culture helps resolution of problems quicker and makes decisions are made on time. This helps to have a continuous focus on the value forecast with respect to the business case and manage the risks that may potentially impact on the expected value.


Principles of Governance

The following are the key governance principles for a successful governance of Agile Delivery:

Focus on the value delivery - only do a task if it brings value to the business. This principle also recognizes the timely delivery of a task as the value derived is more likely to deteriorate with the delayed delivery. In case of Agile deliveries, the governance is continuous and at a work unit level. It should also focus on what activity is taking place and the value such task delivers.

Embrace Change - This another principle of Agile and the Governance framework should take this into consideration. This would mean that the decisions or work flows should be flexible enough to change course based on the feedback received. Given that all stakeholders collaborate, decisions should be taken across the table, without putting things on hold and for the purpose, all needed specialists should take part in the reviews.

Decide on the performance metrics - Another key principle of Agile methodology is to 'fail fast and learn quiuckly'. Given that the overall objective is to improve the certainty that the team will deliver a usable product or service of good quality, the teams should be able to identify and implement the right metrics that will accurately indicate the quality of the deliverables and the performance of the team. For example they measure tasks completed; rework they had to perform; the backlog list and the value of the product or service to the business at the end of each iteration. Teams display this information visually, updating it frequently. This makes progress transparent to business users and management. If senior managers require performance information to oversee projects, they define what the ‘must have’ data are. Performance reports for senior management become a task in each iteration and an output of the delivery team.

Collaboration - All stakeholders, including senior management, external assessors, business users and the development team should be partners in quality, and this collaborative approach is an essential change in mindset. The business owner and delivery team defines what ‘quality’ tests they will use and what results are acceptable at the outset of each iteration – the definition of ‘done’. Regular user feedback identifies whether the product or service is providing the expected business value at each stage. External assessors are not gatekeepers; rather they are an integral part of the team. The iterative approach ensures continual reviews and feedback on progress, so external assessors are not just involved at critical points as defined in a traditional project life cycle.

Focus on behaviours and not just processes and documentation - More specifically, the external reviews or assessments will be more effective in providing critical challenge if the assessors have high-end skills, including technical and Agile delivery experience. In addition, they provide better value if they continually review how the team is performing, using observation as their main method of evidence collection. The focus of such external review or assessment shall be on the following:

• the skills and experience of the team;
• the team dynamics – frequency and nature of communication inside and outside of the delivery team, and the level of input to the delivery team from the business;
• the organisational culture – the level of commitment and openness;
• the timing and nature of quality control by the delivery team – the testing and release framework;
• the order in which the team tackled the tasks – prioritisation of actions and deliverables, the amount of actions in the backlog list;
• the way the team changes its activity in response to the results achieved in each iteration; and
• the value of outputs to the business.

IBM's Disciplined Agile Delivery Methodology


IBM believes Agile delivery allows it to continually issue new capabilities that meet user needs. It usually introduces software as part of a wider business change project so, to keep both in step, it has developed several Agile project methodologies. Disciplined Agile Delivery is a hybrid method that can be applied by a large number of teams working on the same project at the same time. The image below shows the Disciplined Agile Delivery life cycle. It starts with a few short iterations that allow the team and its stakeholders to identify the initial requirements, develop the architecture and agree a release plan. IBM also uses this to determine the system level properties and characteristics – the non-functional requirements. There are iterations after the business owner has decided that the system has sufficient functionality. These additional iterations are necessary for IBM to support the operation and maintenance of the solution once it is in service.



In contrast to the traditional approach of looking at outputs, plans, resourcing and how a project is organised, external assessors should focus on outcomes, prioritisation of work and team dynamics. The most useful indicators of success are how the teams are organising the delivery of an operational service or capability and what Agile behaviours and practices are used. Areas for assessment include whether:
system level issues (security, availability) are addressed within the iterations;

• short- and longer-term planning exists;
• the stakeholders have a shared vision;
• there is continuous integration; and
• the team has the right people

The Principles of Agile Enterprise Architecture Management

Change is happening everywhere and that too at an accelerated rate not only in IT but also in many other functional areas, though the same is very high in the area of IT. Business users are encouraged to innovate in every possible area and that brings in more and more transformation projects, an important category of projects in the enterprise program and portfolio management. Many a times these transformation projects are time critical, which if not implemented on time will use the market advantage. On the same lines, technology adoption is becoming a key aspect for the success of the businesses and the predicting, tracking and embracing the upcoming disruptive technologies has become an important business and strategic risk as it can have wider impact across business strategies, capabilities and processes.

Enterprise Architecture function has equal responsibility in ensuring these changes are embraced with least impact. While running the business as it is an important aspect, enabling transformation of business capabilities and information management capabilities is another key goal for the Enterprise Architects. One of the key elements that Enterprise Architects should consider and address is complexity around business and IT Architecture management so that transformation projects get implemented at desired time schedules and thus reap the intended business benefits. While there are other key objectives like delivering stakeholder value, managing complexity is an objective that comes close to being Agile.

The Agile Enterprise Architecture is all about letting changes happen and thus keep the Architectural Principles continuously evolving. This will also call for having an appropriate lifecycle that facilitates the evolution, development and adaption of the current and the target reference architecture continuously. This will keep the maturity levels of various IT management functions also changing over time. In this blog, let us focus on the key principles that enables an Agile Enterprise Architecture Management:


Value Individuals and Interactions over Tools and Processes

It is a well established and understood fact that it's the people who build success in the enterprise, and the tools and processes are just enablers. With people being the greatest asset, the organizational culture plays an important role in motivating the employees to collaborate, innovate and deliver the results more effectively and efficiently. Build the EA team in such a way that it has representation or interface with the Top Management, Business & IT Owners, Business & IT Operations teams and the Project Teams driving the change within. Choose and deploy the right set of tools, technology and processes that facilitates the collaboration with different business and IT functions.

The EAM team shall aim for sustainable evolution, with a pace as is driven by business and IT users; Help the project teams to avoid panics, and discourage culture clashes; Understand that everyone has their own area of expertise and thus can add value to the project or program.


Focus on demands of top Stakeholders and speak their languages

Typically the top stakeholders need continuous input from the EA team on various business and IT functions, to decide on further strategic alignments or improvements, which in turn would lead to new transformation projects or change of course in case of existing projects. The inputs could be in the form of metrics, visualizations and reports. It is very important that these inputs should be relevant and make sense to the target recipients. The following key considerations are worth considering to ensure that the stakeholders realize the maximum value out of such inputs from EA teams:

• A single number or picture is more helpful than 1000 reports
• Avoid waste - Share information that is relevant and nothing more and nothing less.
• Leverage the existing process to generate and deliver these inputs as against a whole set of EA specific processes.

Promote rapid feedback, by working jointly on models and architecture blue prints with other people and functions. Remember that the best way of conveying information is by a face-to-face conversation, supported by other materials. Shared development of a model, at a whiteboard, will generate excellent feedback and buy-in. Work as closely as possible with all the stakeholders, including your customers and other partners.


Reflect behavior and adapt to changes

The effect of a change in the end reflects on the behavior of individuals, tools, and functions. The EAM function shall atempt to understand the likely directions and behavior of such changes using techniques such as scenario analysis and change cases. This will help the EAM function to determine how best to embrace the change in terms of timing, approach and methodology. This is where a pattern based approach in developing the EAM function would facilitate change adoption with much ease and least impact.

EAM should manage and plan for the changes and shall never resist a change. It may not always be easy in embracing changes, but a well thought out EAM evolution lifecycle would certainly make it simpler. It is always possible that one big change can be broken into various blocks and can be taken one at a time, depending on the time, efforts and business priorities.

Agile in Fixed Price Fixed Scope projects - Hybrid Contracts

It is well known that the traditional methods are not yielding to a better success rate of a project and thus there is a tendency to lean on Agile Methodologies. At the same time, clients feel secure with Fixed Price and Fixed Scope project as their financial outlay is limited and there is no ambiguity. What they miss however in this process is the value delivery. The traditional project management methodologies focus on the Scope, Time and Resources where all three are constraints. Ideally the focus should be on the Value and Quality delivered, given the constraints there by guaranteeing a better success rate of the project.

The software vendors are doing business and they work to earn profits. As such, with Fixed Price projects, the vendors tend to limit their efforts to deliver the agreed scope. With the pace at which changes are happening around any business, freezing scope for a project early on is nearly impossible as software delivered to such scope frozen early on is often less usable. With change is the key driver in optimizing the value delivery, clients and vendors have conflicting views on the change.

Agile methodology has evolved over these years and offers a solution to the problem of optimized value delivery. However, clients still feel that Agile approach does not secure their interests in terms of a definite price and time. Of course, their concern is genuine as they cannot afford to sign a project contract where the cost and time are elastic. While the basic premise of Agile is to embrace the changes, to succeed, it depends on a very high level of trust between the vendors and the clients, where both should work for a common goal and the contract should be profitable to both.

Having said that the Fixed Price (FP) Fixed Scope (FS) contracts offer very limited opportunity for vendors to practice Agile methodology. Making either FP or FS elastic will give some room for practicing Agile methodology. Let us explore how this can be accomplished in the contracts. Both the above contracting models requires a high level of trust between both the vendors and the clients.

Fixed Price Elastic Scope (FPES) contract: In this model, while the price is fixed, the scope can be variable. This model can practice a hybrid Agile approach, the scope is broken down to features and the development happens feature by feature. Depending the time taken to implement a feature, more features are added or removed. For instance, if a feature estimated to take 30 days is implemented in 20 days, one or more new features can be added to fill the time saved. Similarly if the implementation takes 45 days, then one or more features will be removed.

To bring in incentive for both vendors and clients, a discount factor can be agreed upon, which is applied while adding or removing features. For instance, in a case where the vendor has saved 10 days for a feature, the client instead of adding a feature that needs 10 days to fill the gap, will only add a feature with 5 days of effort, where the discount factor would be 50%. The same discount factor is applied on the converse (where implementation exceeds the planned effort).

Elastic Price Fixed Scope (EPFS) contract: In this model, the Scope is fixed, but the pricing is variable. The idea behind this approach to is arrive at a base rate and a profit factor. While the base rate and the profit factor, along with the generic terms and conditions are covered in the Master Services Agreement, the actual project scope can be covered in multiple Statement of Works (SoW). Requirement elicitation and scoping can be the first SoW. This way, the project can be split into smaller working software modules and the work items can be scoped in stages / phases. This approach will help the clients in handling changes with ease.

Here again, an approach like 60:40:20 can be adopted to prioritize the work items. This approach requires the work items to be grouped into Must have features, Good to have features and Fixes. Every SoW can comprise of 60% of Must Haves, 40% of Good to haves and 20% of fixes emerged out of previous deliveries.

The incentives for both vendors and clients can be based on categorization of the work items as New feature, Clarification, Fixes. New features are the scope items as elaborated during elicitation. Clarifications are such items that emerge out of elicited requirements during the design or build phase. Fixes are incorrect implementations by the vendors, basically design and build defects. Costs for each SoW can be computed by applying the profit factor on the base rate. For instance, the New features will be charged at base rate + profit, clarifications will be charged at base rate and fixes will be charged at base rate - profit.

With the above, we are not concluding that Agile cannot be practiced in an FPFS project. There are still ways and means that a hybrid agile approach can be thought of and practiced so that value delivery is the primary focus for all the parties. Do share your thoughts in the form of comments on the subject, and I will cover those in my next blog.
