Speed up On-Premises Product Delivery

Fast delivery of value to customers is today’s business mantra – especially in the software industry. In this blog I reflect on delivery challenges of companies which offer the same product as SaaS AND on-premises solution. I will also present a case study that shows how a company has dramatically improved its on-premises delivery speed.

Within the past 15 years we have seen several approaches how to foster fast delivery of software products. Two prominent ones are:

  • Agile development
  • Cloud based solutions

The agile approach to software development produces software products incrementally and frequently. This is achieved by close interaction with customers and a set of development principles that are based on the agile manifesto. It is not uncommon that software companies create new versions of their software products on a monthly or even shorter frequency.

How are these product increments delivered to the customer?

Currently there are two major mechanisms in use:

The fastest way for on-premises provisioned products, is to check during launch if there is a newer version of the product available. If so, the newer version will be automatically downloaded and installed. This practice is often used within the software games industry. E.g. games that are provisioned by the steam gaming platform. Traditional ways to deliver a new on-premises version are customer notifications combined with manual on-demand-downloads.

SaaS provisioned products are often under control of the company in charge for the development of the product. Whenever the development organization has produced and tested a new product increment, it will be moved to the SaaS server. Customers that launch the product through their web browser are automatically connected to the latest version of the product. Cloud-based solutions enable software vendors to deliver new software features quite often to their customers. The only thing left to do is to update the software on the runtime environment that is often under their own control. In such environments it is not uncommon that bug fixes and new features are delivered on a weekly or even on a daily basis.

The dual-delivery challenge

Companies which started business after the millennium focus often on cloud based solutions and do not provide on-premises products. In contrast, companies that have been around for more than 15 years are used to on-premises delivery and have established their business around that channel. However, more and more of those companies start to deliver their products as SaaS-based products in addition. Prominent examples are Microsoft with their office suite and HPE with their ALM solution.

Serving two channels with the same product creates new challenges. Customers that utilize on-premises products often have to wait for more than a year to get new features. Features which they can already see within the SaaS version of the same product. This situation creates quite some tension. Therefore, product companies try shortening the delivery cycles for on-premises solutions as well.

The company Jama Software was faced with this challenge and recently came up with a new release model for their on-premises release stream of the requirements product named Jama.

Case study Jama

Jama Software prefers the SaaS delivery channel. However, they accept that some of their customers do not want data managed outside their company’s intranet. Especially, if the data contains sensitive information about upcoming product releases which is usually the case when managing requirements.

As a consequence, Jama Software delivers its product as a hosted solution via SaaS AND as an on-premises solution. Typically, they release two on-premises versions within a year. However, customers using the SaaS version get access to new product features much earlier.

In summer 2016 Jama Software announced a significantly changed new release mechanism: On-premises Express. With the on-premises express channel they aim to deliver new versions on a monthly base. Compared to the half year release schedule so far this represents a stunning acceleration in delivery.

What are the secrets to Jama Software’s cycle time reduction?

First of all: A thorough analysis of the current situation. Finding out the areas of work that need a lot of time for each release. The current server part of the product Jama is delivered on two operating systems: Windows and Linux. All used 3rd party components need to be available on both platforms at the same time. So far Jama Software supports two database systems: MySQL and Oracle. Features and bug-fixes need to be tested on both platforms and DBs. Testing bug fixes and new product features on the various configurations consumes quite some time.

Jama product management made the tough decision to drop support for Microsoft Windows server and Oracle DB. This enabled the QA organization to substantially reduce time for testing. Now Jama Software delivers the same software configuration to their customers that they use on their hosted platform as well.

Second, they analyzed their current architecture in regards to ease of modification. They found out, that they could improve their product significantly by a new way of modularization.

Third, they decided to utilize top-notch technology for isolating the product into distinct independent components, thereby easing software distribution. Jama Software decided to utilize Docker containers. They now encapsulate product dependencies like Java and Tomcat into containers, so that customers don’t need to care about specific Java or Tomcat versions.

Fourth, accelerating deployment. Jama software now uses Replicated. This technology takes advantage of Docker and deploys containers not only to the SaaS server of the vendor but also behind a customer’s firewall. Using Replicated Jama Software now builds the product just once and deploys the result simultaneously to their own hosted instance and to registered customers.

Develop and Deploy

Encapsulating product services into Docker container and managing deployment with Replicated enables Jama Software to manage deployment of the service-oriented architecture much faster, more flexible and more reliable than before.

Summary

Achieving cycle time reduction in development is just one element to deliver software to customers more frequently. It needs to be matched by fast deployment methods, so that the whole DevOps chain can be covered. On top of that the product managers of Jama Software needed to make some tough decisions what not to support in the future. These decisions took complexity out of the product and significantly reduced testing time. Product managers are responsible for the overall product success. They have a holistic view of the business and need to look at all aspects along the delivery chain of a product in order to come up with solutions that enable sustainable business success. Jama Software has rebuild major elements along that line.

We may expect similar moves by other vendors this year as they all face similar pressures.
Stay tuned.

Overview of VersionOne Updates

VersionOne is one of the leading agile tools that we feature in our list of requirements management tools. In an earlier blog post from 2015, we surveyed its then latest developments. These were: Epic Dependency Visualization, Strategic Themes, Epic Timeline Drilldown and Scorecards.

Now we find it’s time for an update. Since spring 2015, VersionOne has delivered several builds, bundled into 3 major release streams named Summer 2015, Fall 2015, and recently in January the Winter 2016 release.

This blog post highlights and summarizes some of the major capabilities that have been added in the timeframe since our previous blog. Note that feature capabilities depend on the VersionOne edition chosen by an organization. For an overview of the four editions Team, Catalyst, Enterprise and Ultimate look up the VersionOne edition overview.

The Summer release 2015 provided enhanced visibility about commit information. The CommitStream TeamRoom panel provides the stream of commit data relevant to all work items for the entire list of repositories that has been configured. The panel can be configured by users to view only the repository commit information they are interested in.

Project management support has been enhanced by introducing budgeting capabilities. Total capacity may be allocated to the entire organization for a certain timeframe and then split into project based budget segments. The Fall release 2016 added capabilities to set budget for strategic themes. These capabilities are available under the topic of portfolio planning.

The Winter release 2016 added a Timesheet feature which allows team members to enter time spent on work items in an environment they are used to. The Timesheet page displays a team members time tracked against items for an entire week.

Reporting capabilities got enhanced in every release. The Summer release 2015 provided additional scorecards, like TeamRoom Scorecard and Iteration Scorecard.

The Winter 2016 release provided a new dashboard at the enterprise level. This Enterprise Dashboard visualizes organizational metrics in the categories: Throughput, Responsiveness, Quality, and Predictability.

DevOps has become a major theme in recent years. As a strategic response to that VersionOne acquired ClearCode Labs to add continuous delivery and automation functionality into its product offering. In the Summer release 2016 DevOps Center was added to the VersionOne product as a first step.

In the Winter release 2016, VersionOne announced that DevOps release automation is now available as a separate product named: Continuum. Continuum helps with automating, orchestrating and visualizing the flow of releases and their associated changes from inception to delivery.

As a consequence, the company VersionOne now offers two products:

  • VersionOne Lifecyle – Agile project and portfolio planning, tracking and reporting
  • VersionOne Continuum – Continuous delivery automation, orchestration and visualization

Kanban support in team rooms is now available. Teams are no longer required to have an open sprint/iteration. TeamRooms can now be configured as “iterationless”, which allows for true Kanban support.

Summary

VersionOne continuously broadens its capabilities in their already rich featured agile tool. From our point of view, it delivers one of the most complete solutions for agile teams. While they have added impressive support for large scale agile development in recent years, they did not neglect to refactor and streamline their core offerings as triggered by requests from their user base.

Aha

Recently we updated our annotated collection of requirements management tools. In this update we introduced a couple of new tools, which we got notice from. One of them is the product Aha!.

Aha! is a cloud based solution targeted at product managers. It has been created in 2013 and focuses on product planning aspects. The company Aha! positions the product as roadmapping software. Product managers can specify high level goals and visions for products. Continue reading

Agile Requirements Frameworks

by Andreas Birk and Gerald Heller

When agile methods emerged during the 1990s and until quite long into the first decade of the 21st century, agile requirements were widely synonymous with user stories. This was a major contribution and step forward for requirements practices on team level. However, for larger multi-team development efforts, for continuous product development as well as for product- and portfolio-level planning, effective guidance for agile requirements management was still mostly missing. This situation has improved gradually since around 2005 when frameworks for scaling agile appeared on the scene. Most notable examples are: Scaling Software Agility by Dean Leffingwell (2007) and Scaling Lean & Agile Development by Craig Larman and Bas Vodde (2008). Follow-up publications of these authors have provided valuable additional guidance also for requirements management. In particular, Dean Leffingwell published the first comprehensive agile requirements framework in 2010: Agile Software Requirements, the approach is now known as the Scaled Agile Framework (SAFe).

Today, we have quite a variety of agile requirements frameworks. But now it has become difficult to survey the entire scene and find the suitable approaches relevant for one’s own specific software or system development context. For this reason, we want to give an overview here, providing orientation and guidance in the growing field of agile requirements management. You find a survey of those frameworks we find most important along with links for further information. Of course, this selection is subjective, and for sure we have overlooked some important approaches. So we will be grateful, if you can comment on the following list and send us additional hints (feedback link). We will include them into future updates of this list.

Scaled Agile Framework SAFe (Leffingwell)

SAFe has been the first comprehensive framework for agile requirements management, defined by Dean Leffingwell. Published in its initial version in 2010 and partly based on earlier works, we view it still as the most important reference and entry point for agile requirements management. The website provides a very rich collection of valuable information. The book is an excellent introduction and resource on agile requirements. Dean Leffingwell’s earlier book makes a good extension for understanding the large-scale agile development process.

Scaling Lean & Agile Development LeSS (Larman, Vodde)

LeSS does not focus on requirements management in particular, rather it addresses the entire spectrum of agile development activities. However, it includes very many practices and techniques relevant to agile requirements management. A good introduction to LeSS is the May 2013 article in CrossTalk magazine. Additional information provide the homepages and blogs of Craig Larman and Bas Vodde. An interesting experience report is the article on Large Scale Scrum (LeSS) @ J.P. Morgan at InfoQ. The comprehensive resources are the two books on basic concepts (2008) and on practices (2010) of the approach.

Disciplined Agile Delivery DAD (Ambler)

DAD is a “process decision framework” that aims at helping projects and organizations to create their suitable agile development approaches. As such it includes various agile requirements practices along with guidance to design requirements and software delivery processes. The approach is relatively new, dating from 2012. There is an accompanying book available.

Discover to Deliver (Gottesdiener)

Discover to Deliver is an approach to agile product planning and (requirements/business/system) analysis. It extends established product planning and analysis techniques and transforms them into the agile world. A book introduces the approach, and a short 2-minutes video clip explains the essential concepts.

Specification by Example SBE (Adzic, Fowler, and others)

“Specification by example (SBE) is a collaborative approach to defining requirements and business-oriented functional tests for software products based on capturing and illustrating requirements using realistic examples instead of abstract statements.” (Wikipedia) It provides a consistent framework to agile requirements management utilizing high-level tests and test automation. Among the main proponents are Gojko Adzic and Martin Fowler. Gojko Adzic maintains the specificationbyexample.com website and has written a good instructive book on the topic. Martin Fowler has written a concise article that motivates and introduces the approach.

Acceptance Test Driven Development ATDD (Gärtner, Koskela, and others)

ATDD is another consistent approach for accomplishing agile requirements and testing tasks in an integrated fashion. It features several agile requirements practices that can be very useful in the context of other approaches as well (e.g., the Given-When-Then template for specifying system behaviour and tests). A Wikipedia article provides a good introduction. Introductory books are available from Markus Gärtner. Lasse Koskela has written a brief introduction as well as a very instructive book on ATDD.

User Stories Applied (Cohn)

User stories are the nucleous or starting point of all agile requirements management. Mike Cohn’s classical book on the topic provides an excellent introduction and explains the application of use cases in agile development projects.

Use Case 2.0 (Jacobson)

Ivar Jacobson has coined the concept of use cases as early as in the 1980s. With Use Case 2.0 he and his colleagues have refurbished the use cases approach for the agile age. The approach differs partly from other agile requirements frameworks (e.g., stronger emphasize on more or less formal information structure and (only) apparently less emphasis on stakeholder communication procedures). However, this makes it particularly relevant as a source of additional inspiration for agile requirements managers. It also can provide important guidance for environments in which other agile approaches don’t appear suitable (e.g., possibly in development of technical products using model-based approaches). An eBook explains the approach.

Agile Product Canvas (Pichler)

Roman Pichler is the author of the book Agile Product Management with Scrum (2010). Since then he has developed several additional and very useful tools. One of them is the Agile Product Canvas, which collects all important overall product-related requirements information on one easy-to-understand and easy-to-use pane.

Agile Modeling & Agile Documentation (Ambler, Rüping and others)

Quite early during the emergence of agile methods, Scott Ambler and Andreas Rüping had taken attention to aspects beyond coding. First, Scott Ambler wrote a book on agile modeling (2002). He also now maintains a comprehensive website on the topic, which contains a good overview article. Soon later, Andreas Rüping has added another book on agile documentation (2003). In 2012, Andreas Rüping published an updated and extended version of the book (available in German only). These works complement the other frameworks on agile requirements management by providing guidance also for the interfaces of requirements management to adjacent disciplines like graphical modeling (e.g., business process models, UML, SysML), architecture specifications, and user documentation.

At the end of this article, let us emphasize again: We will be very glad, if you share your thoughts on agile requirements management with us. Do you disagree with (parts of) what we have written here? Would you have additional framework suggestions? Do you have agile requirements experiences that you want to share with others?

Survey of Requirements Tools Lists

For the February 2014 update of our list of requirements management (RM) tools, my colleague Gerald Heller and I researched for other lists of requirements tools, in order to extend and complement our collection. In the following you find the results of our investigation. Each list has its specific strengths and focus areas that are outlined in brief comments on each entry.

Requirements Management Tools

INCOSE’s RM Tools List (http://www.incose.org/productspubs/products/rmsurvey.aspx) has been the first large RM tools list we know of that was researched systematically. It is supplied with an extensive collection of (vendor-provided) tool characterizations. Unfortunately, the last update is from 2010 and much information stems even from 2008, so that most of the detailed tool information must be regarded outdated.

Volere’s RM Tools List: http://volere.co.uk/tools.htm. Vendors provide their own brief tool characterizations. Much information is not fully up to date. But the rather extensive list provides an easy to read overview of the RM Tools landscape.

Iain Alexander’s ’s RM Tools List at http://www.scenarioplus.org.uk/vendors.htm includes many tools that are not contained in INCOSE’s and Volere’s collections. A large subsection is on tools for requirements quality analysis.

The Tools Journal’s RM Tools List (http://www.toolsjournal.com/requirements-management-tools) is another list that provides a good overview of tools. But it also most information is not up-to-date.

Capterra’s list of requirements management products (http://www.capterra.com/requirements-management-software) contains about 40 tools and provides filtering support with regard to tool features.

Ludwig Consulting Services provide a fairly up-to-date list (http://www.jiludwig.com/Requirements_Management_Tools.html) that has last been updated in 2012 but also mentions some outdated tools. It includes a brief informative introduction text and contains some tools not provided in the previous lists.

IEEE Software magazine from July/August 2011 includes a tools survey (http://www.computer.org/csdl/mags/so/2011/04/mso2011040086-abs.html) that contains an elaborated overview characterization of 37 tools. The authors have set up a web page with brief characterizations of the tools. A PDF version of the article is also available from Vector’s media portal.

Ideation Tools

Ideation tools list at CreatingMinds.org: http://creatingminds.org/tools/tools_ideation.htm. It contains tools from various different areas, many of which can be relevant in certain requirements elicitation and requirements definition activities.
