Time to Production: DevSecOps – the deployment pipeline for secure software

Many companies today align their software development with the DevOps model. But saving time alone is not enough, security aspects must be included from the very beginning – keyword: DevSecOps.

The second article in my series “Time to Production” has shown the optimization potential that system operation and administration can achieve through close cooperation with development, QA and product managers as well as consistent use of tools. However, it is too short-sighted to use a deployment pipeline to make new code available to users in real time: the pipeline should also deliver a secure application in a secure and monitored system environment.

Time to Production: DevOps – agility in systems operation

The DevOps model brings developers and administrators closer together and enables agile methods in both areas.

In the first article of my “Time to Production” series, I highlighted best practices for optimizing the time it takes for a new feature from a product owner’s request to the completion of development. With the completion of software development, however, the feature is not yet available to users in the production system. The idea of also speeding up the second part of the supply chain after a change has been handed over to the operator – without any compromise in availability, security or other quality features – is obvious. Here too, the application of agile principles is promising. DevOps – the composition of the terms development and operations – is a model and not a role. It is neither meant that developers take over the task of operators and administrators, nor vice versa. Content of the DevOps model is the interdepartmental cooperation between development, quality assurance and operation as well as the implementation of best practices in software development in the field of service management and system administration.

Time to Production: How much agility is good for software development?

Time to Production: How much agility is good for software development?

Agile methods can help to increase the productivity and quality of processes as well as of the developed software. A consideration of the success criteria.

Productivity is an important key figure in software development. It determines which software volume an organization can create with a certain amount of effort while adhering to certain quality criteria. We have already published several articles about our experiences with its measurement and optimization. However, high productivity in software development alone does not say anything about how quickly a new feature of an application can be used in production by users – the so-called Time to Production. My new series of articles deals with this topic.

Productive insight: Monitoring in software development

Productive Insight: Monitoring in Software Development

In software development, a selective measurement of productivity can be very deceptive. Valid statements require consideration over a longer period of time.

In one of my previous contributions, I described how the management model used at PASS for several years works. In brief: It is based on three key performance indicators (productivity, costs and quality) and the corresponding measurement methods. Continue reading 

Software Development: Every Error Is an Opportunity

Through the cyclical repetition of measurements, evaluations and optimizations a targeted improvement of productivity and quality can be achieved in software development. Thereby error analysis is an essential part of this process.

When processing an error, the focus is naturally on correcting it in order to eliminate the user’s restrictions on the use of the system. In many cases, agreed response or troubleshooting times require a quick focus on a solution, even if it is only a workaround solution that does not prevent the error from occurring in the long term.

Productive software development requires a management model

Productive Software Development Requires a Management Model

How can productivity and quality in software development be managed effectively and sustainably controlled? A KPI-based management model as response.

In my last articleThree levers for higher productivity in software development, I used empirical values to show how industrial methods, such as standardization and automation, affect productivity. Thus, software development by industrial means does not aim at mass production of similar products; on the contrary, it enables a high degree of individualization by a small-scale standardization of business-related and technical components.

Three levers for higher productivity in software development

Three Levers for Higher Productivity in Software Development

Costs down – quality up: productivity in software development is a triad of development standards, automation and reuse.

In my article “Individual Standard: Mass Customization in Software Development” I pointed out how optimization potentials can be exploited by reusing fine-granular business and technical components. Here, the development of a travel management system served as an example with a total of 2,286 man days saved. Considering this impressive figure, the question arises: To what extent can the productivity in the development of individual systems be increased?

New book: Increasing Productivity of Software Development

Increasing Productivity of Software Development – Part 2

Developed from practice to practice: Today I present the second book of my series “Increasing Productivity of Software Development”. Topics are the application, evaluation and optimization of the KPIs productivity, costs and quality.

While the first book figured out experiences with different measuring methods, my second book entitled “Management Model, Cost Estimation and KPI Improvement” describes a management model based on key performance indicators. Continue reading 

Increasing Productivity of Software Development – a book presentation

Increasing Productivity of Software Development – a Book Launch

Complex requirements, ever shorter development periods and increasing cost pressure – productivity is an issue of increasing importance in software development. This is the starting point for my book project “Productivity and Performance Measurement – Measurability and Methods”.

As Head of the Competence Center Project Governance, I am responsible for the process engineering for software development at PASS. For several years we have been using key performance indicators as a major information source of our IT management – in more than ten different application environments with more than 500 customers and approx. 250,000 users. In some areas our regularly measured KPIs show significantly higher delivery productivity. Continue reading 

Individual Standard: Mass Customization in Software Development

Individual Standard: Mass Customization in Software Development

Industrialization vs. individualization = mass vs. individual production – an equation which has largely lost its validity today. In the industrial sector as well as in software development the future belongs to customized mass production (mass customization).

For a long time, mass production allowed an optimum utilization of operating assets and thus higher quantities, shorter delivery times and lower product prices than individual production which is rather characterized by more attractive and usable products. Continue reading 

Java 9 – Evolutionary or Revolutionary Development?

Java 9 – Evolutionary or Revolutionary Development?

In just over six months, it will be ready: The Java release 9 is coming. Today we already take a look at what’s new – what is arriving and what is not.

As we constantly observe market as well as technology trends and how they can benefit the travel industry, this time we wanted to highlight the next Java version, which is just around the corner. This becomes specifically interesting as we are in the process of providing value added travel services completely decoupled from the user interface as a restful interface so that anybody can create an innovative user interface and book travel – be it chatbots, virtual agents, a mobile interface or an Online Booking Tool.

Software Development: Buy or mAKE? Just BAKE!

Software Development: Buy or mAKE? Just BAKE!

A really good end product is often the result of the perfect mix of ingredients – not only when baking a cake, but also in software development.

Software is the central ingredient of digitization. Innovative products and services are no longer conceivable without it. Competitiveness crucially depends on the ability to create software-intensive products and services quickly and with highest quality. In software development, one therefore has to face the make-or-buy decision. Continue reading 

How German Start-ups care about Quality

Software Engineering by start-ups – chaos and bugs instead of structure and quality? This was the title of a conference by the German federal association for the ITC industry BITKOM in mid-April. Its purpose was an exchange between established ITC companies and start-ups.

In particular, the key questions were: how chaotic are the conditions under which start-ups actually develop software – and of which importance is quality management to them. The location was suited to address these issues: the Hasso-Plattner-Institute for software systems engineering (HPI) in Potsdam, which already has supported numerous start-ups in the IT business.
